Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American professor of Paleontology in Yale College and President of the National Academy of Sciences . He was one of the preeminent scientists in the field of paleontology. Among his legacies are the discovery or description of dozens of new species and theories on the origins of birds.

85-460: Compsognathus ( / k ɒ m p ˈ s ɒ ɡ n ə θ ə s / ; Greek kompsos /κομψός; "elegant", "refined" or "dainty", and gnathos /γνάθος; "jaw") is a genus of small, bipedal , carnivorous theropod dinosaur . Members of its single species Compsognathus longipes could grow to around the size of a chicken . They lived about 150  million years ago , during the Tithonian age of

170-695: A natural history museum at Yale . While studying at the University of Berlin in late 1863, the 32-year-old Marsh first met 25-year-old Edward Drinker Cope , who was also on a scientific tour of Europe. Cope had much less formal schooling than Marsh, but had already published thirty-seven papers. The two Americans spent a few days together and would become friends. After a salmon fishing excursion with Peabody in Ireland, Marsh returned to America in July or August 1865. Marsh had expected Peabody's gift would have resulted in

255-537: A pitch accent . In Modern Greek, all vowels and consonants are short. Many vowels and diphthongs once pronounced distinctly are pronounced as /i/ ( iotacism ). Some of the stops and glides in diphthongs have become fricatives , and the pitch accent has changed to a stress accent . Many of the changes took place in the Koine Greek period. The writing system of Modern Greek, however, does not reflect all pronunciation changes. The examples below represent Attic Greek in

340-417: A century, Compsognathus longipes was the only well-known small theropod species. This led to comparisons with Archaeopteryx and to suggestions of an especially close relationship with birds. In fact, Compsognathus , rather than Archaeopteryx , piqued Huxley's interest in the origin of birds. The two animals share similarities in shape and proportions, so many in fact that two specimens of Archaeopteryx ,

425-509: A hundred new species of vertebrate fossils. After 1876, Marsh employed bone hunters who shipped specimens back to him; he did not return west himself until 1879. When Cope began prospecting for fossils in the Bridger Basin, which Marsh considered "his" territory, their relationship deteriorated into hostility. Marsh served as Vertebrate Paleontologist of the U.S. Geological Survey from 1882 to 1892. Thanks to John Wesley Powell , head of

510-472: A lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period. They have the same general outline but differ in some of the detail. The only attested dialect from this period is Mycenaean Greek , but its relationship to the historical dialects and

595-419: A lesser degree. Pamphylian Greek , spoken in a small area on the southwestern coast of Anatolia and little preserved in inscriptions, may be either a fifth major dialect group, or it is Mycenaean Greek overlaid by Doric, with a non-Greek native influence. Regarding the speech of the ancient Macedonians diverse theories have been put forward, but the epigraphic activity and the archaeological discoveries in

680-471: A meeting of the American Association, Marsh elected to join other members to Omaha on a "geological excursion"; it was Marsh's first trip to the far western United States, and it inspired him to return to prospect. Marsh organized a series of private expeditions starting in 1870 to 1874, with the prospecting groups composed of Yale students or recent graduates. The first of these uncovered more than

765-615: A new clade of dinosaurs, the Symphypoda, which also contained Ornithotarsus (today classified as Hadrosaurus ). Later, both genera were found to belong to other groups of Cope's classification of dinosaurs: Compsognathus to the Gonipoda (equivalent to Theropoda , in which it is now classified), and Ornithotarsus to the Orthopoda (equivalent to Ornithischia ). Huxley, in 1870, rejected Cope's dinosaur classification scheme, and instead proposed

850-562: A patch of fossilized skin from the tail and hindlimb of the possible relative Juravenator starki shows mainly scales, though there is some indication that simple feathers were also present in the preserved areas. This may mean that a feather covering was not ubiquitous in this group of dinosaurs, or maybe that some species had fewer feathers than others. Originally classified as a lizard, the dinosaurian affinities of Compsognathus were first noted by Gegenbaur, Cope, and Huxley between 1863 and 1868. Cope, in 1870, classified Compsognathus within

935-440: A position at Yale, but it took until 1866 when Yale established a chair of paleontology at the university. Marsh was given the position, but no salary was attached; biographer George Grinnell suggested that this suited Marsh just fine, as he was more interested in research than teaching. Marsh's interests shifted entirely to paleontology, and after 1869 his other scientific contributions mostly ceased. While teaching, Marsh toured

1020-543: A prefix /e-/, called the augment . This was probably originally a separate word, meaning something like "then", added because tenses in PIE had primarily aspectual meaning. The augment is added to the indicative of the aorist, imperfect, and pluperfect, but not to any of the other forms of the aorist (no other forms of the imperfect and pluperfect exist). The two kinds of augment in Greek are syllabic and quantitative. The syllabic augment

1105-419: A professor of science. While in graduate school, Marsh published his first scientific papers on minerals and vertebrate fossils from his Nova Scotia trips, which possibly inspired Marsh's interest in vertebrate paleontology. He obtained his masters degree in 1862. Following school, Marsh declined a professorship at Yale and instead took a tour of Europe; it is possible the trip was to avoid being drafted into

1190-992: A record 1400 scientific papers. Marsh named the following dinosaur genera : He named the suborders Ceratopsia (1890), Ceratosauria (1884), Ornithopoda (1881), Stegosauria (1877), and Theropoda (1881). He also named the families Allosauridae (1878), Anchisauridae (1885), Camptosauridae (1885), Ceratopsidae (1890), Ceratosauridae , Coeluridae , Diplodocidae (1884), Dryptosauridae (1890), Nodosauridae (1890), Ornithomimidae (1890), Plateosauridae (1895), and Stegosauridae (1880). Marsh dubbed many additional species of dinosaur as well, notable taxa including Allosaurus fragilis , Triceratops horridus , Stegosaurus stenops , Ornithomimus velox , and Brontosaurus excelsus . Dinosaurs named by others in honour of Marsh include Hoplitosaurus marshi (Lucas, 1901), Iaceornis marshi (Clarke, 2004), Marshosaurus (Madsen, 1976), Othnielia (Galton, 1977), and Othnielosaurus (Galton, 2007). Marsh's finds formed

1275-671: A separate historical stage, though its earliest form closely resembles Attic Greek , and its latest form approaches Medieval Greek , and Koine may be classified as Ancient Greek in a wider sense. There were several regional dialects of Ancient Greek; Attic Greek developed into Koine. Ancient Greek was a pluricentric language , divided into many dialects. The main dialect groups are Attic and Ionic , Aeolic , Arcadocypriot , and Doric , many of them with several subdivisions. Some dialects are found in standardized literary forms in literature , while others are attested only in inscriptions. There are also several historical forms. Homeric Greek

1360-609: A standard subject of study in educational institutions of the Western world since the Renaissance . This article primarily contains information about the Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period ( c.  300 BC ), Ancient Greek was followed by Koine Greek , which is regarded as

1445-510: A vowel or /n s r/ ; final stops were lost, as in γάλα "milk", compared with γάλακτος "of milk" (genitive). Ancient Greek of the classical period also differed in both the inventory and distribution of original PIE phonemes due to numerous sound changes, notably the following: The pronunciation of Ancient Greek was very different from that of Modern Greek . Ancient Greek had long and short vowels ; many diphthongs ; double and single consonants; voiced, voiceless, and aspirated stops ; and

1530-556: Is a literary form of Archaic Greek (derived primarily from Ionic and Aeolic) used in the epic poems , the Iliad and the Odyssey , and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic and other Classical-era dialects. The origins, early form and development of the Hellenic language family are not well understood because of

1615-418: Is added to stems beginning with consonants, and simply prefixes e (stems beginning with r , however, add er ). The quantitative augment is added to stems beginning with vowels, and involves lengthening the vowel: Some verbs augment irregularly; the most common variation is e → ei . The irregularity can be explained diachronically by the loss of s between vowels, or that of the letter w , which affected

1700-705: Is an alternative phylogeny, published by Cau in 2024, with both specimens in bold. Siamraptor Siamotyrannus Streptospondylus Xuanhanosaurus Poekilopleuron Piveteausaurus Piatnitzkysaurus Marshosaurus Leshansaurus Eustreptospondylus Condorraptor Asfaltovenator Sciurumimus Nedcolbertia Magnosaurus Duriavenator Afrovenator Compsognathus longipes Compsognathus corallestris Torvosaurus tanneri Torvosaurus gurneyi Megalosaurus Scipionyx Wiehenvenator Ancient Greek Ancient Greek ( Ἑλληνῐκή , Hellēnikḗ ; [hellɛːnikɛ́ː] ) includes

1785-644: Is called 'East Greek'. Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian Greek had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect, as exemplified in the poems of the Boeotian poet Pindar who wrote in Doric with a small Aeolic admixture. Thessalian likewise had come under Northwest Greek influence, though to

1870-448: Is considered by some linguists to have been closely related to Greek . Among Indo-European branches with living descendants, Greek is often argued to have the closest genetic ties with Armenian (see also Graeco-Armenian ) and Indo-Iranian languages (see Graeco-Aryan ). Ancient Greek differs from Proto-Indo-European (PIE) and other Indo-European languages in certain ways. In phonotactics , ancient Greek words could end only in

1955-459: Is the first theropod dinosaur known from a reasonably complete fossil skeleton. Until the 1990s, it was the smallest-known non- avialan dinosaur, with the preceding centuries incorrectly labelling them as the closest relative of Archaeopteryx . Compsognathus is known from two almost complete skeletons. The German specimen (specimen number BSP AS I 563) stems from limestone deposits in Bavaria and

2040-481: The American Civil War , although he might have also been disqualified from service on account of his eyesight. Marsh traveled through England, France, Germany, and Switzerland, studying with or making the acquaintance of prominent scientists such as Heinrich Ernst Beyrich , Wilhelm Peters , Christian Gottfried Ehrenberg and Henry Woodward . In discussions with his uncle, Marsh convinced the businessman to fund

2125-572: The Compsognathus specimen, was acquired by the paleontological state collection in Munich . Both the year of discovery and the exact locality of the German specimen are unknown, possibly because Oberndorfer did not reveal details of the discovery to prevent other collectors from exploiting the locality; later authors have suggested that the German specimen was probably discovered during the 1850s. Weathering of

2210-745: The Greek region of Macedonia during the last decades has brought to light documents, among which the first texts written in Macedonian , such as the Pella curse tablet , as Hatzopoulos and other scholars note. Based on the conclusions drawn by several studies and findings such as Pella curse tablet , Emilio Crespo and other scholars suggest that ancient Macedonian was a Northwest Doric dialect , which shares isoglosses with its neighboring Thessalian dialects spoken in northeastern Thessaly . Some have also suggested an Aeolic Greek classification. The Lesbian dialect

2295-501: The present , future , and imperfect are imperfective in aspect; the aorist , present perfect , pluperfect and future perfect are perfective in aspect. Most tenses display all four moods and three voices, although there is no future subjunctive or imperative. Also, there is no imperfect subjunctive, optative or imperative. The infinitives and participles correspond to the finite combinations of tense, aspect, and voice. The indicative of past tenses adds (conceptually, at least)

2380-507: The "Eichstätt" and the "Solnhofen", were for a time misidentified as those of Compsognathus . Many other types of theropod dinosaurs, such as maniraptorans , are now known to have been more closely related to birds. Below is a simplified cladogram placing Compsognathus in Compsognathidae by Senter et al. in 2012. Sinocalliopteryx Huaxiagnathus Sinosauropteryx Compsognathus Juravenator Scipionyx Here

2465-462: The 1630s. Mary died shortly after the birth of her fourth child in 1834. Caleb remarried in 1836 and Othniel moved with the family to Bradford, Massachusetts . Soon after, Caleb's business fortunes soured, and Othniel's early years were marked by financial struggles. Caleb purchased a farm in Lockport when Marsh was twelve. As the eldest son, Othniel was expected to assist his father on the farm, and

2550-1031: The 5th century BC. Ancient pronunciation cannot be reconstructed with certainty, but Greek from the period is well documented, and there is little disagreement among linguists as to the general nature of the sounds that the letters represent. /oː/ raised to [uː] , probably by the 4th century BC. Greek, like all of the older Indo-European languages , is highly inflected. It is highly archaic in its preservation of Proto-Indo-European forms. In ancient Greek, nouns (including proper nouns) have five cases ( nominative , genitive , dative , accusative , and vocative ), three genders ( masculine , feminine , and neuter ), and three numbers (singular, dual , and plural ). Verbs have four moods ( indicative , imperative , subjunctive , and optative ) and three voices (active, middle, and passive ), as well as three persons (first, second, and third) and various other forms. Verbs are conjugated through seven combinations of tenses and aspect (generally simply called "tenses"):

2635-490: The Archaic period of ancient Greek (see Homeric Greek for more details): Μῆνιν ἄειδε, θεά, Πηληϊάδεω Ἀχιλῆος οὐλομένην, ἣ μυρί' Ἀχαιοῖς ἄλγε' ἔθηκε, πολλὰς δ' ἰφθίμους ψυχὰς Ἄϊδι προΐαψεν ἡρώων, αὐτοὺς δὲ ἑλώρια τεῦχε κύνεσσιν οἰωνοῖσί τε πᾶσι· Διὸς δ' ἐτελείετο βουλή· ἐξ οὗ δὴ τὰ πρῶτα διαστήτην ἐρίσαντε Ἀτρεΐδης τε ἄναξ ἀνδρῶν καὶ δῖος Ἀχιλλεύς.

This evolutionary law remains being used due to its explanatory, and to a certain extent, predictive potential Prior to Marsh's efforts, the entirety of fossil remains known in North America was quite small. As a result of the generosity of George Peabody , Marsh

2890-856: The Peabody fossil hall. He donated his home in New Haven, Connecticut, to Yale University in 1899. The Othniel C. Marsh House , now known as Marsh Hall, is designated a National Historic Landmark . Marsh Hall serves as the home of the Yale School of Forestry at the Yale School of the Environment . The grounds are now known as the Marsh Botanical Garden . Marsh was elected a member of the American Antiquarian Society in 1877. Marsh formulated

2975-639: The USGS, and Marsh's contacts in Washington, Marsh was placed at the head of the consolidated government survey in the late 1880s. In 1880, Marsh caught the attention of the scientific world with the publication of Odontornithes: a Monograph on Extinct Birds of North America, which included his discoveries of birds with teeth. These skeletons helped bridge the gap between dinosaurs and birds, and provided invaluable support for Darwin's theory of evolution. Darwin wrote to Marsh saying, "Your work on these old birds & on

3060-550: The aorist. Following Homer 's practice, the augment is sometimes not made in poetry , especially epic poetry. The augment sometimes substitutes for reduplication; see below. Almost all forms of the perfect, pluperfect, and future perfect reduplicate the initial syllable of the verb stem. (A few irregular forms of perfect do not reduplicate, whereas a handful of irregular aorists reduplicate.) The three types of reduplication are: Irregular duplication can be understood diachronically. For example, lambanō (root lab ) has

Marsh's criticism wrankled Cope, and threatened his nascent career; he responded by critiquing errors in Marsh's work, and moving in on areas Marsh was prospecting in. Their relationship began to sour. Marsh was looking further afield than New Jersey for fossils. After visiting Chicago for

3230-419: The augment when it was word-initial. In verbs with a preposition as a prefix, the augment is placed not at the start of the word, but between the preposition and the original verb. For example, προσ(-)βάλλω (I attack) goes to προσ έ βαλoν in the aorist. However compound verbs consisting of a prefix that is not a preposition retain the augment at the start of the word: αὐτο(-)μολῶ goes to ηὐ τομόλησα in

3315-575: The backbone of the collections of Yale's Peabody Museum of Natural History and the Smithsonian Institution . Marsh has been called "both a superb paleontologist and the greatest proponent of Darwinism in nineteenth-century America." Othniel Charles Marsh was born on October 29, 1831, near Lockport, New York. He was the third of four children born to Mary Gaines Peabody (1807–1834) and Caleb Marsh (1800–1865). The Marsh (nee Marshe) family and Peabody families immigrated to America from England in

3400-438: The center of Greek scholarship, this division of people and language is quite similar to the results of modern archaeological-linguistic investigation. One standard formulation for the dialects is: West vs. non-West Greek is the strongest-marked and earliest division, with non-West in subsets of Ionic-Attic (or Attic-Ionic) and Aeolic vs. Arcadocypriot, or Aeolic and Arcado-Cypriot vs. Ionic-Attic. Often non-West

3485-460: The compsognathids to be an example of convergent evolution . The position of Compsognathus and its relatives within the coelurosaur group is uncertain. Some, such as theropod expert Thomas Holtz Jr. and co-authors Ralph Molnar and Phil Currie in the landmark 2004 text Dinosauria , hold the family as the most basal of the coelurosaurs, while others as part of the Maniraptora .

3570-587: The country, visiting museums to inform the planning of the Yale Museum. In 1868, he visited Cope; since their meeting, they had expressed warm wishes in letters to each other and even named species after each other. Cope took Marsh on a tour of the marl pits in New Jersey where he was finding fossils; unbeknownst to Cope, Marsh would later pay the pit operators to divert their finds to him instead of Cope. Marsh later noted that Cope's reconstruction of his newest find,

3655-611: The dialect of Sparta ), and Northern Peloponnesus Doric (including Corinthian ). All the groups were represented by colonies beyond Greece proper as well, and these colonies generally developed local characteristics, often under the influence of settlers or neighbors speaking different Greek dialects. After the conquests of Alexander the Great in the late 4th century BC, a new international dialect known as Koine or Common Greek developed, largely based on Attic Greek , but with influence from other dialects. This dialect slowly replaced most of

3740-562: The first two digits, leading to the suggestion that Compsognathus bore only two functional digits, with the third metacarpal being extremely slender and reduced. Study of the French specimen indicated that the third digit bore at least one or two small phalanges. However, there remains no evidence for an ungual phalanx on the third digit, so the digit may have been reduced and non-functional. Some relatives of Compsognathus , namely Sinosauropteryx and Sinocalliopteryx , have been preserved with

3825-466: The foot did probably not belong to Compsognathus itself but to a closely related genus. Ostrom, in his 1978 monography, questioned the attribution of this fossil to Compsognathus once more. Jens Zinke, in 1998, assigned forty-nine isolated teeth from the Guimarota coal mine of Portugal to the genus. Zinke found that these teeth are not identical to those of Compsognathus longipes , having serrations on

3910-663: The forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek ( c.  1400–1200 BC ), Dark Ages ( c.  1200–800 BC ), the Archaic or Epic period ( c.  800–500 BC ), and the Classical period ( c.  500–300 BC ). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers . It has contributed many words to English vocabulary and has been

3995-410: The front edge, and thus labeled the teeth as Compsognathus sp. (of unknown species). For decades, Compsognathus was known as the smallest known non-avian dinosaur , although some dinosaurs discovered later, such as Mahakala and Microraptor , were even smaller. The German specimen was estimated to be 70–75 cm (28–30 in) and 89 cm (35 in) in length by separate authors, while

4080-401: The frontmost teeth of the upper and lower jaws were unserrated , while those further back had fine serrations on their rear edges. In the German specimen, the crowns were around two times higher than wide in the front of the jaws but diminished in height further back, with the last tooth about as high as wide. The German specimen also shows a diastema (tooth gap) behind the first three teeth of

4165-556: The historical Dorians . The invasion is known to have displaced population to the later Attic-Ionic regions, who regarded themselves as descendants of the population displaced by or contending with the Dorians. The Greeks of this period believed there were three major divisions of all Greek people – Dorians, Aeolians, and Ionians (including Athenians), each with their own defining and distinctive dialects. Allowing for their oversight of Arcadian, an obscure mountain dialect, and Cypriot, far from

4250-472: The historical circumstances of the times imply that the overall groups already existed in some form. Scholars assume that major Ancient Greek period dialect groups developed not later than 1120 BC, at the time of the Dorian invasions —and that their first appearances as precise alphabetic writing began in the 8th century BC. The invasion would not be "Dorian" unless the invaders had some cultural relationship to

4335-499: The larger French specimen was estimated at 1.25 m (4 ft 1 in) and 1.4 m (4 ft 7 in) in length. The height at the hip has been estimated at 20 cm (7.9 in) for the German specimen and at 29 cm (11 in) for the French specimen. The German specimen was estimated to have weighed 0.32 kg (0.71 lb) and 0.58 kg (1.3 lb), and the French specimen 2.5 kg (5.5 lb) and 3.5 kg (7.7 lb). Compared to other compsognathids,

4420-555: The larger French specimen would have been similar in size to larger Sinosauropteryx specimens, but smaller than Huaxiagnathus and Mirischia . Compsognathus were small, bipedal animals with long hind legs and longer tails, which they used for balance during locomotion. The forelimbs were smaller than the hindlimbs. The hand bore two large, clawed digits and a third, smaller digit that may have been non-functional. Their delicate skulls were narrow and long, with tapered snouts. The skull had five pairs of fenestrae (skull openings),

4505-449: The largest of which was for the orbit (eye socket), with the eyes being larger in proportion to the rest of the skull. The lower jaw was slender and had no mandibular fenestra, a hole in the side of the lower jawbone commonly seen in archosaurs . The teeth were small and pointed, suited for its diet of small vertebrates and possibly other small animals, such as insects. The German specimen had three teeth in each premaxilla (front bone of

4590-627: The late Jurassic period , in what is now Europe . Paleontologists have found two well-preserved fossils , one in Germany in the 1850s and the second in France more than a century later. Today, C. longipes is the only recognized species, although the larger specimen discovered in France in the 1970s was once thought to belong to a separate species and named C. corallestris . Many presentations still describe Compsognathus as "chicken-sized" dinosaurs because of

4675-427: The lower jaw), 15 or 16 teeth in each maxilla, and 18 teeth in the lower jaw. The French specimen had more teeth, including four in each premaxilla, 17 or 18 in the maxilla, and at least 21 teeth in the dentary. Compsognathids were unique among theropods in having tooth crowns that curved backwards at two thirds of their height, while their mid-parts were straight; also, the crowns had expanded bases. In Compsognathus ,

America has afforded the best support to the theory of evolution, which has appeared within the last 20 years" (since Darwin's publication of Origin of Species). Between 1883 and 1895, Marsh was President of the National Academy of Sciences . The pinnacle of Marsh's work with dinosaurs came in 1896 with the publication of his two quartos, Dinosaurs of North America and Vertebrate Fossils, which demonstrated his unsurpassed knowledge of

4845-582: The new clade Ornithoscelida , in which he included the Dinosauria (comprising several forms now considered as ornithischians) and another new clade, the Compsognatha, which contained Compsognathus as the only member. Later, these groups fell into disuse, although a resurrection of the Ornithoscelida was proposed in 2017. The group Compsognatha was used for the last time by Marsh in a 1896 publication, where it

4930-418: The new find under a separate species, Compsognathus corallestris . A more comprehensive description followed in the same year. According to these authors, the new species differed from the German species in its larger size and modified, flipper-like hand. Ostrom, Jean-Guy Michard and others have since relabeled it as another example of Compsognathus longipes . In 1984, George Callison and Helen Quimby identified

5015-499: The newly discovered French specimen in 1978, making Compsognathus one of the best-known small theropods at that time. He also concluded that the German specimen likely belongs to an immature individual. The larger French specimen (Y85R M4M) was discovered in around 1971 in the Portlandian lithographic limestone of Canjuers near Nice . It dates to the lower Tithonian, as indicated by ammonite index fossils . As Solnhofen, Canjures

The museum's Great Hall is dominated by the first fossil skeleton of Brontosaurus that he discovered, which was reclassified as Apatosaurus for a time. However, an extensive study published in 2015 concluded that Brontosaurus was a valid genus of sauropod distinct from Apatosaurus .

He was initially an unremarkable student, devoting much of his time to leisure and games, but the next year decided to focus on his studies. "I changed my mind," he later told a biographer, "during an afternoon spent on Dracut Heights [Lowell]. I resolved that I would return to Andover, take hold, and really study." Marsh applied himself to his studies and graduated valedictorian of his class in 1856. In

Reduplication is also visible in the present tense stems of certain verbs. These stems add a syllable consisting of the root's initial consonant followed by i . A nasal stop appears after the reduplication in some verbs. The earliest extant examples of ancient Greek writing ( c.  1450 BC ) are in

5440-417: The premaxilla. As such a gap was not present in the French specimen, Peyer suggested that additional teeth were possibly present in this region the German specimen. The number of digits on the hand of Compsognathus has been a source of debate. For much of its history, Compsognathus was typically depicted with three digits, as is typical for theropods. However, the type specimen only preserved phalanges from

The limestone of the area, the Solnhofen limestone , had been quarried for centuries, and yielded such well-preserved fossils as Archaeopteryx with feather impressions and pterosaurs with imprints of their wing membranes. In two publications in 1868 and 1870, Thomas Huxley , a major proponent of Charles Darwin 's theory of evolution, compared Compsognathus with Archaeopteryx , which

5610-406: The remains of simple feathers covering the body like fur, prompting some scientists to suggest that Compsognathus might have been feathered in a similar way. Consequently, many depictions of Compsognathus show them with coverings of downy proto-feathers. However, no feathers or feather-like covering have been preserved with Compsognathus fossils, in contrast to Archaeopteryx , which are found in

5695-402: The right ankle from the slab for illustration and study; this removed part got lost since. Although Baur published a detailed study of the ankle in 1882, which is now the only available source of information of this part of the skeleton, his reconstruction was later found to be inconsistent with corresponding impressions on the slab. John Ostrom thoroughly described the German specimen as well as

5780-672: The same sediments. Karin Peyer, in 2006, reported skin impressions preserved on the side of the tail starting at the 13th tail vertebra. The impressions showed small bumpy tubercles, similar to the scales found on the tail and hind legs of Juravenator . Additional scales had in 1901 been reported by Von Huene, in the abdominal region of the German Compsognathus , but Ostrom subsequently disproved this interpretation; in 2012 they were by Achim Reisdorf seen as plaques of adipocere , corpse wax. Like Compsognathus , and unlike Sinosauropteryx ,

5865-455: The size of the German specimen, which is now believed to be a juvenile. Compsognathus longipes is one of the few dinosaur species whose diet is known with certainty: the remains of small, agile lizards are preserved in the bellies of both specimens. Teeth discovered in Portugal may be further fossil remains of the genus. Although not recognized as such at the time of its discovery, Compsognathus

5950-514: The slab on which the fossil is preserved indicates that it was collected from a pile of waste rock left behind by quarrying. The specimen either stems from Jachenhausen or the region Riedenburg–Kehlheim. All possible localities are part of lagoonal deposits of the Painten Formation , and date to the latest part of the late Kimmeridgian or the earlier part of the early Tithonian . In the Jurassic,

6035-412: The smaller German specimen as a juvenile of the same species. Collector Heinrich Fischer had originally labeled a partial foot consisting of three metatarsals and a phalanx, from the Solnhofen area, as belonging to Compsognathus longipes . This identification was rejected by Wilhelm Dames, when he described the specimen for the first time in 1884. Friedrich von Huene , in 1925 and 1932, also found that

6120-589: The subject. On December 13, 1897, Marsh received the Cuvier Prize of 1,500 francs from the French Academy of Science . According to Peter Dodson , Cope and Marsh "[have] left a legacy, and each was a distinguished researcher. But really it seems impossible to say one name without the other. Cope and Marsh." Marsh's names for three dinosaur groups, and nineteen genera, have survived, and though only three of Cope's named genera are still in use, he published

6205-587: The summers off of school, he prospected for minerals in New York, Massachusetts, and Nova Scotia. Upon gradation, Marsh decided to attend Yale, rather than Harvard, where many of his relatives had attended. He ran his letter to George Peabody asking for the funds by Aunt Judith first, who disapprovingly noted it contained two spelling errors. Peabody agreed to cover Marsh's expenses and give him an allowance for spending money, and Marsh moved to New Haven in September. Marsh

6290-517: The syllabic script Linear B . Beginning in the 8th century BC, however, the Greek alphabet became standard, albeit with some variation among dialects. Early texts are written in boustrophedon style, but left-to-right became standard during the classic period. Modern editions of ancient Greek texts are usually written with accents and breathing marks , interword spacing , modern punctuation , and sometimes mixed case , but these were all introduced later. The beginning of Homer 's Iliad exemplifies

6375-485: The two had a contentious relationship. Othniel much preferred excursions in the woods to his chores. Among his childhood influences was Ezekiel Jewett, a former military officer and amateur scientist who influenced Othniel's interest in the sciences. Jewett had been drawn to the area by the fossils unearthed by the enlargement of the Erie Canal , and the two would hunt and prospect for specimens together. By 1847, Othniel

6460-466: The world, studying anatomy , mineralogy and geology . He obtained a teaching position at Yale upon his return. From the 1870s to 1890s, he competed with rival paleontologist Edward Drinker Cope in a period of frenzied Western American expeditions known as the Bone Wars . Marsh's greatest legacy is the collection of Mesozoic reptiles, Cretaceous birds, and Mesozoic and Tertiary mammals that now constitute

6545-475: Was Aeolic. For example, fragments of the works of the poet Sappho from the island of Lesbos are in Aeolian. Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, or to an island. Doric notably had several intermediate divisions as well, into Island Doric (including Cretan Doric ), Southern Peloponnesus Doric (including Laconian ,

6630-463: Was a good student, but not a thrifty one; Aunt Judith, who was in charge of monitoring Marsh while Peabody was in Europe, regularly upbraided her nephew for his lax accounting habits and large expenses. Marsh graduated eighth in his class, using a scholarship he won for the best examination in Greek to finance a masters degree from Yale's Sheffield Scientific School , as he developed an interest in becoming

6715-489: Was able to keep discovery teams in the field almost continuously from 1870 until his death. The material recovered in his 30 years of collection was simply astonishing to the scientific community. At the Peabody Museum, Marsh was the first to create skeletal displays of dinosaurs, which are now common in countless museums of natural history. Marsh biographer Mark J. McCarren summed it up this way, Marsh's "contributions to

6800-632: Was attending school at the Wilson Collegiate Institute , and later attended the Lockport Union School. Othniel was undecided as to what he would do for a living, but the course of his future was dramatically changed due to the intervention of his uncle George Peabody , who was a successful banker. With Peabody's financial assistance (spurred by Marsh's aunt, Judith), Marsh enrolled in Phillips Academy in 1851. Older than most of

6885-607: Was considered the earliest known bird. Following earlier suggestions by Carl Gegenbaur and Edward Drinker Cope , Huxley found that Archaeopteryx was closely similar to Compsognathus , and referred to the latter as a "bird-like reptile". He concluded that birds must have evolved from dinosaurs, an assessment that established Compsognathus as one of the most widely known dinosaurs. The specimen has since been studied by many prominent paleontologists, including Othniel Charles Marsh , who visited Munich in 1881. The German paleontologist J.G. Baur, who worked as an assistant of Marsh, removed

6970-629: Was famous for its limestone plates, which were quarried and sold under the name "dalles de Provence". The specimen was originally part of a large private fossil collection of Louis Ghirardi, the owner of the Canjures quarries. The collection, including the Compsognathus specimen, was sold to the National Museum of Natural History in Paris in 1983. Alain Bidar and Gérard Thomel, in a brief 1972 description, announced

7055-477: Was part of the collection of the physician and fossil collector Joseph Oberndorfer. Oberndorfer lent the specimen to paleontologist Johann A. Wagner , who published a brief discussion in 1859, where he coined the name Compsognathus longipes . Wagner did not recognise Compsognathus as a dinosaur, but instead described it as one of the "most curious forms among the lizards". He published a more detailed description in 1861. In 1866, Oberndorfer's collection, including

7140-430: Was the only member known, but in recent decades paleontologists have discovered several related genera. The clade includes Aristosuchus , Huaxiagnathus , Mirischia , Sinosauropteryx , and perhaps Juravenator and Scipionyx . At one time, Mononykus was proposed as a member of the family, but this was rejected by Chen and coauthors in a 1998 paper; they considered the similarities between Mononykus and

7225-490: Was treated as a suborder of Theropoda. In the same publication, Marsh erected the new family Compsognathidae . Friedrich von Huene, in 1914, erected the new infraorder Coelurosauria , which includes the Compsognathidae amongst other families of small theropods; this classification remained in use since. The Compsognathidae are a group of mostly small dinosaurs from the late Jurassic and early Cretaceous periods of China, Europe and South America. For many years, Compsognathus
