Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.
The second toe, which was shorter and had fewer phalanges, also had more resistance and would make it easier to hold the claw off the ground and retain prey, a compromise with its predatory function and movement on the run, as occurs with modern seriemas, although to a lesser degree of specialization than dromaeosaurid dinosaurs.

The remains were found by geology students Brian Watkins and Eric Gutiérrez on an expedition led by Andrew McDonald of the Western Science Center, and Douglas Wolfe, the CEO of the Zuni Dinosaur Institute for Geosciences. Subsequent expeditions at the Menefee Formation in 2013 and 2018 did not reveal any additional elements.

The Indian fossil record of dinosaurs is good, with fossils coming from the entire Mesozoic era – starting with the Triassic period (a geological period that started 251.9 million years ago and continued till 201.3 million years ago), to the Jurassic period (201 million years ago to 145 million years ago) and Cretaceous period (from 145 ...
2024 marks 200 years since the first dinosaur, Megalosaurus, was formally identified. Here’s what we’ve learned about the prehistoric creatures over the past two centuries.
The footprints date back to about 166 million years ago and appear to belong to two distinct types of dinosaurs ... Scientists have found the U.K.’s largest dinosaur footprint site ever.
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
