Dinosaurs snapped their jaws like crocodiles
Chewing might not sound like an amazing ability, but it’s actually an animal superpower.
All animals with jaws can move them up and down against each other at least a little bit, and this lets them bite prey, grab plants between their teeth, or groom themselves.
The ancestors of mammals like giraffes, humans, mice and opossums first evolved in the Triassic period, and they brought an amazing new skill to the world.
These new mammals had special bones that let their jaws move
in a different way – they could
move their bottom jaws from side
to side. Give it a try! From mice to mammoths, hyenas to hedgehogs – almost all mammals are able to chew.
Dinosaurs, on the other hand, could only move their jaws up and down. Sure, some dinosaurs, like A Q U I L A R H I N U S , had amazing crazy-looking shovel-mouths for scooping through aquatic plants and some, like
L I M U S A U R U S , grew a beak as they became older, but no dinosaurs could mush up their food by moving their teeth left and right against each other, like you can today.
