Non-avian dinosaur and bird fossils are frequently found in a characteristic posture consisting of head thrown back, tail extended, and mouth wide open. The cause of this posture—often called a "death pose"—has been a matter of scientific debate.
Pterodactylus (from Ancient Greek: πτεροδάκτυλος, romanized: pterodáktylos ' winged finger ' [2]) is a genus of extinct pterosaurs.It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered.
While very little is known about pterosaur reproduction, it is believed that, similar to all dinosaurs, all pterosaurs reproduced by laying eggs, though such findings are very rare. The first known pterosaur eggs were found in the quarries of Liaoning, the same place that yielded feathered dinosaurs, and in Loma del Pterodaustro ( Lagarcito ...
Pterodactyloids were the last surviving pterosaurs when the order became extinct at the end of the Cretaceous Period, together with the non-avian dinosaurs and most marine reptiles. "Pterodactyl" is also a common term for pterodactyloid pterosaurs, though it can also be used to refer to Pterodactylus specifically.
Dinosaurs were the largest terrestrial animals for much of the Mesozoic Era, and one group of small feathered dinosaurs (Aves, i.e. birds) has survived up to the present day. Pterosaurs were the first flying vertebrates and persisted through the Mesozoic before dying out at the Cretaceous-Paleogene (K-Pg) extinction event.
The researchers said that of all the cosmic bodies they have studied that struck Earth in the last 500 million years, only the one that exterminated the dinosaurs was a water-rich asteroid.
As Texas baked in record-breaking heat this summer and a growing drought pushed water levels down, a group of volunteers uncovered something sort of magnificent: new giant dinosaur tracks that are ...
Pterodaustro has about a thousand bristle-like modified teeth in its lower jaws that might have been used to strain crustaceans, plankton, algae, and other small creatures from the water. [5] These teeth stand for the most part not in separate alveoli but in two long grooves parallel to the edges of the jaw. They have a length of 3 centimeters ...
