32-615: A Massachusetts man died in New Hampshire after sinking into the water during a failed skimming attempt. In July 2010, a 40-year-old man died in Anaktuvuk Pass while attempting to skim across Eleanor Lake. In January 2018, a 48-year-old man died after partially skipping across Sturgeon Lake (Ontario) .

96-591: Is controversial. Some studies, including one by Lü and colleagues in 2008, have found that the thalassodromines are more closely related to the azhdarchids than to the tapejarids , and have placed them in their own family (which has sometimes been referred to as Tupuxuaridae , though Thalassodrominae was named first). Alternately, they have been considered a family within the clade Neoazhdarchia , as Thalassodromidae . Below are three alternate cladograms resulting from studies of azhdarchoid relationships. The first, presented by Felipe Pinheiro and colleagues in 2011, found

However, their remains are fragmentary, so this assignment is only tentative, and a 2021 study further show dissimilarities between them and azhdarchids, with Aerotitan being a true azhdarchid while Alanqa was

160-481: The rider and sled do not complete the course, the rider releases the buoy from the snowmobile so that it floats to the surface and marks the sled for retrieval. Watercross competitions, as with other motor sports competitions, have ambulance and rescue crews nearby in the event of an accident. While it is possible to skim over the water with a stock snowmobile, the practice can be dangerous. For example, in February 2006,

On September 18, 2015, the record is now set at 212  km (131.731 miles) by the Norwegian Morten Blien . Watercross competitions are held during the summer and the participants of official events wear life jackets and helmets, and have a buoy tethered to their sleds. If for some event

208-497: The sled's throttle open, the track keeps the snowmobile on the surface of the water without sinking. If the rider backs out of the throttle or the sled bogs or floods out, the sled will sink. A sunk sled is able to be revived by cleaning water out of the carburetor , exhaust, spark plugs, and replacing the fuel. The front of the sled is pitched upwards as riders commonly do in deep mountain powder snow. The Grantsburg, Wisconsin first annual World Championship Snowmobile Watercross

224-755: The thalassodromines as a subgroup within the Tapejaridae. The second, presented by Lü and colleagues in 2008, found them to be closer to the Azhdarchidae, though they used the name Tupuxuaridae for the group. The third, presented by Brian Andres, James Clark and Xu Xing in 2014, also found thalassodromines closer to azhdarchids, and as the sister group of the dsungaripterids .

The first race was simply held to see who could make it the 300 feet (91 m) from the island on Memory Lake to the shore. Most didn't, but the winner did go about 500 ft (150 m). In the years following, racers became more skilled and machines more powerful. Today, racers compete in drags and ovals, with an eight-lap championship run. Over 100 racers compete in
