Scratches on dinosaur teeth could reveal what they really ate. For the first time, dental microwear texture analysis (DMTA) has been used to infer the feeding habits of large theropods, including Allosaurus and T. rex. By taking 3D images of individual teeth and analyzing the pattern of mark
A landmark study has revealed that dinosaurs dominated the world right up until a deadly asteroid hit the earth, leading to their mass extinction, some 66 million years ago.
Pterosaurs, the flying reptiles of the dinosaur era, originated in the Late Triassic (227 million years ago) and became extinct at the end-Cretaceous extinction event (66 million years ago). With wing spans ranging from 1 to 12 meters, they dominated the world's skies for more than 160 milli
University of Manchester research fellow David Legg, in collaboration with a team of international scientists from China, Switzerland, and Sweden, has announced a new fossil that reveals the origin of gills in arthropods.
Jeholornis was a raven-sized bird that lived 120 million years ago, among the earliest examples of dinosaurs evolving into birds, in what's now China. The fossils that have been found are finely preserved but smashed flat, the result of layers of sediment being deposited over the years. That
Washington [US], October 14 (ANI): A process of desiccation and deflation explains why dinosaur 'mummies' aren't as exceptional as we might expect, according to a study.
Washington [US], October 7 (ANI): 66 million years ago, a 10-kilometre asteroid hit Earth, triggering the extinction of the dinosaurs. New evidence suggests that the Chicxulub impact also triggered an earthquake so massive that it shook the planet for weeks to months after the collision. The
Washington [US], October 6 (ANI): A new study of a tiny Triassic fossil reptile first discovered over 100 years ago in the northeast of Scotland has revealed it to be a close relative of the species that would become pterosaurs' iconic flying reptiles of the age of the dinosaurs.
Washington [US], September 24 (ANI): While the vast majority of asteroids and comets are not dangerous, and never will be, it's also true that 66 million years ago, a giant asteroid impact on the Earth likely caused the extinction of the dinosaurs.
Washington [US], September 23 (ANI): Researchers have conducted a new analysis of the origins of 'bird-hipped' dinosaurs -- the group which includes iconic species such as Triceratops -- and found that they likely evolved from a group of animals known as silesaurs, which were first identifie
