The physiology of dinosaurs has historically been a controversial subject, particularly their thermoregulation.Recently, many new lines of evidence have been brought to bear on dinosaur physiology generally, including not only metabolic systems and thermoregulation, but on respiratory and cardiovascular systems as well.
The new Bexhill-on-Sea dinosaurs are represented by teeth alone. The team used several techniques, including machine learning methods, to analyse the fossils.
Tyrannosaurus (/ t ɪ ˌ r æ n ə ˈ s ɔː r ə s, t aɪ-/) [a] is a genus of large theropod dinosaur.The type species Tyrannosaurus rex (rex meaning 'king' in Latin), often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods.
It included a Velociraptor attacking a Protoceratops, [172] providing evidence that dinosaurs did indeed attack each other. [173] Additional evidence for attacking live prey is the partially healed tail of an Edmontosaurus, a hadrosaurid dinosaur; the tail is damaged in such a way that shows the animal was bitten by a tyrannosaur but survived ...
Triceratops (/ t r aɪ ˈ s ɛr ə t ɒ p s / try-SERR-ə-tops; [1] lit. ' three-horned face ') is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago in what is now western North America.
Dinosaurs were initially cold-blooded, but global warming 180 million years ago may have triggered the evolution of warm-blooded species, a new study found.
What they really needed to find was the dinosaur’s “motor,” so to speak, which would show how it could navigate at ease for longer periods of time in water. Most dinosaurs didn’t swim ...
Pachycephalosaurus gives its name to Pachycephalosauria, a clade of herbivorous ornithischian dinosaurs that lived during the Late Cretaceous period in North America and Asia. Pachycephalosaurs were a part of Marginocephalia , thus being likely more closely related to the ceratopsians than the ornithopods .
