The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 161.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata .
3-708: The Toutunhe Formation is a Late Jurassic geological formation in China, specifically dating to the Oxfordian and Kimmeridgian stages. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The lower portion of the formation consists of grey to reddish mudstone with medium to coarse grained cross bedded sandstone, while the upper portion consists primarily of brown-red-purple mudstone, interbedded with fine to medium grained laminated sandstone.

6-521: A specific stratigraphic formation in the People's Republic of China is a stub . You can help Misplaced Pages by expanding it . Late Jurassic In European lithostratigraphy , the name " Malm " indicates rocks of Late Jurassic age. In the past, Malm was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. The Late Jurassic
9-619: Is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: During the Late Jurassic Epoch, Pangaea broke up into two supercontinents , Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean . However, at this time, the Atlantic Ocean was relatively narrow. This epoch is well known for many famous types of dinosaurs , such as
