Thanks to popular culture, most of us are familiar with the giant Theropod Tyrannosaurus rex. Colloquially, the animal is known as T.rex or T-Rex, short for its scientific name – Tyrannosaurus rex. At the time, T.rex was one of the most carnivorous dinosaurs.
In fact, a full-grown T-rex would reach over 20 feet long – about as tall as an ape. But the movies don’t explain everything about this magnificent animal, and some facts may have been misrepresented. The latest research allows us to rediscover some details about Tyrannosaurus Rex in a new way.
Contrary to popular belief, T. rex did not survive the Jurassic period. This happened at the end of the Cretaceous period, which was about 85 – 65 million years ago.
Fossil evidence indicates that T.rex had a wide distribution – from Canada in the north to New Mexico in the south. The ecosystems that it occupied at that time included arid plains, tropical coastal areas and inland areas. Global average temperatures were also much warmer than today.
T.rex was one of the best carnivorous dinosaurs to roam the earth. And that was because of his unique teeth. The teeth of the T. rex were serrated, like a steak knife.
Upon closer inspection, scientists saw patterns of tooth tissue that looked like cracks, which they believed were damaged – by heavy use and tear feeding but turned out to be a mass of internal species – the tissues inside each tooth were arranged in different ways.
meant that the teeth were almost intact and very hard. This was very important for the carnivores, and in most cases was one of the reasons for the success of the T.rex.
