For decades, world scientists have been arguing about what they were. dinosaurs: cold-blooded or warm-blooded. Now experts finally came to a final conclusion and reported that prehistoric reptiles clearly possessed homeothermia, i.e. warm-bloodedness.
>Новое исследование американских палеонтологов представилоa second analysis of a scientific study conducted a year ago. Then experts attributed the ancient dinosaurs to the mesotherms. Right now scientists found that the growth rate and metabolism of dinosaurs and modern mammals are remarkably similar. In other words, dinosaurs were homeothermic, warm-blooded creatures.
The original survey was an analysis of twenty-one species of prehistoric reptiles, including apatosaurus, tyrannosaurus, troodon, tenontosaurus, velociraptor, triceratops and gallimimus. Then the researchers studied the growth of the bones of the dinosaurs and concluded that dinosaurs were neither cold-blooded nor warm-blooded animals, and occupied an intermediate link, being the so-called mesotherms.
Now scientists from the University of New York have proved that The growth rate of reptile bones was not studied correctly by their colleagues. Dinosaurs were unable to change their body temperature under environmental exposure. Consequently, these creatures were warm-blooded and kept constant bodily temperature outside depending on the ambient temperature.
