A major discovery.
This Friday, an international team of paleontologists published the results of a stunning study in the journal Science. In fact, these scientists were able to examine the contents of the stomach of a tyrannosaurus, as reported by our colleagues at 324.
This fossilized dinosaur was discovered in 2009, Alberta (Canada). In such impeccable condition that following several years of work, experts were able to determine what he had eaten in his last two meals. And learn lessons that change the perception of these large predators.
Hind limbs only
Ce Gorgosaurus libratus was between 5 and 7 years old. He weighed 350 kg and was just under 4 meters tall. The remains of two small herbivores (Citipes) “bird-like” were found in his stomach. A first lesson for researchers: the young tyrannosaurus hunted all alone and did not feed on the remains of adults, as the international scientific community previously thought.
“Tyrannosaurus actually only ate the hind limbs of each of these prey”, even specifies the co-author of the study, Darla Zelenitsky. Quite the opposite of adults who ate any part of their prey. A behavior that changes from the age of 11, according to Quebecer François Therrien.
