The known fossils of Quetzalcoatlus were discovered in Big Bend National Park, Texas. The genus Quetzalcoatlus is based on fossils discovered in rocks pertaining to the Late Cretaceous Javelina Formation in Big Bend National Park, Texas. Remains of dinosaurs and other prehistoric life had been found in the area since the beginning of the 20th ...
Lawson began his synecological research during his master's degree studying the paleoecology of the Tornillo Formation in Big Bend National Park, Texas.During his study of this Late Cretaceous intermontane basin community, he discovered the fossil remains of the giant pterosaur, Quetzalcoatlus Northropi, which he named in honor of John K. Northrop because of its similarity to Northrop's flying ...
The majority of the fossil remains of Cryodrakon, among them its holotype bones, most likely represented young and subadult individuals. Their dimensions are similar to those of Quetzalcoatlus sp. (now known as the species Q. lawsoni [8]). A wingspan of at least 5 m (16 ft) has been set for Cryodrakon based on these smaller remains.
The outcrop, situated in the middle strata of the formation about 90 meters below the K-Pg boundary and within the local range of Alamosaurus fossils and below two sites that have yielded Quetzalcoatlus fossils, was dated to 69.0 plus or minus 0.9 million years old in 2010. [2] Indeterminate chasmosaurinae fossils have also been as well. [5]
Well-known examples of pterodactyloids include Pterodactylus, Pteranodon, and Quetzalcoatlus. In 2014, fossils from the Shishugou Formation of China were classified as the most basal pterodactyloid yet found, Kryptodrakon. At a minimum age of about 161 my, it is about 5 million years older than the oldest previously known confirmed specimens. [4]
New research shows that Homo sapiens traveled from Africa to East Asia and toward Australia up to 86,000 years ago.
Aloft over the landscape of Bavaria some 147 million years ago was a pterosaur - an ancient flying reptile - with a wing span of about 7 feet (2 meters), a bony crest on front of its snout and a ...
The ghost of both of these is evident from the fossils found in the area," said Adele Pentland, a doctoral student in paleontology at Curtin University in Australia and lead author of the study ...
