Physiology of dinosaurs. 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.
Gigantothermy (sometimes called ectothermic homeothermy or inertial homeothermy) is a phenomenon with significance in biology and paleontology, whereby large, bulky ectothermic animals are more easily able to maintain a constant, relatively high body temperature than smaller animals by virtue of their smaller surface-area-to-volume ratio.

The dinosaur renaissance[ 1 ] was a highly specified scientific revolution that began in the late 1960s and led to renewed academic and popular interest in dinosaurs. It was initially spurred on by research indicating that dinosaurs may have been active warm-blooded animals, rather than sluggish cold-blooded lizard-like reptilians as had been ...
Mounted skeletons of different age groups, Los Angeles Natural History Museum. The feeding behaviour of Tyrannosaurus rex has been studied extensively. The well known attributes of T. rex (its jaws, legs and overall body design) are often interpreted to be indicative of either a predatory or scavenging lifestyle, and as such the biomechanics, feeding strategies and diet of Tyrannosaurus have ...
A new species of dinosaur has been identified more than a decade after a large number of ancient skeletons were found in Spain -- and researchers expect more species to be discovered. The ...
Julia Musto. September 5, 2024 at 3:15 PM. Paleontologists have discovered a new species of dinosaur that lived in Spain some 75 million years ago. The sauropod — dinosaurs that are ...
While the dinosaurs met their end around 66 million years ago in a catastrophic way, their extinction may have been crucial to the development of the human race.
Dinosaurs are a diverse group of reptiles [ note 1 ] of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is a subject of active research.
