What Did T. rex Do?


Dinosaurs’ lives are a mystery. Fossils can’t tell us exactly how they acted or what their families were like. But scientists can make a good guess by comparing T. rex fossils to animals alive today.


Ostriches make nests with a mound of eggs. No fossils of? T. rex eggs have been found yet, but scientists have found other theropods’ nests with a similar mound.


This bearded vulture eats meat and bones. Pieces of bone have been found in T. rex poop, so these dinosaurs probably snacked on bones, too!


Lions use their noses to find food. T. rex likely did the same, but its sense of smell was not as good as a lion’s.


In the movies, the roar of a T. rex sends animals (and people) running. But T. rex likely didn’t roar like a lion. Instead, it probably hissed like a crocodile.

Do you see any lions?

No. No crocs either.
