Tyrannosaurus rex had teeth like a STEAK KNIFE: Serrated bite of carnivores could crush bones, analysis reveals
If you want to know the secret behind the success of Tyrannosaurus rex and its meat-eating dinosaur cousins, look no further than their teeth.
A carnivorous group called theropods had serrated teeth like a steak knife that let them chomp efficiently through the flesh and bones of their prey.
Theropods included the largest land predators in Earth’s history, including the infamous Tyrannosaurus rex.
They first appeared about 200 million years ago and were the dominant terrestrial meat-eaters until the age of dinosaurs ended about 65 million years ago.
The study involving eight theropod species revealed their previously unknown tooth complexity.
Internal dental tissues were arranged in a way that reinforced the strength and prolonged the life of teeth that were serrated like steak knives for easy dismembering of other dinosaurs.
