Fossil counterpart: Edit
Some 66 million years ago, Ankylosaurus roamed what is now North America. They lived alongside dinosaurs like Tyrannosaurus rex, Triceratops, And Pachycephalosaurus. They had rounder armor than what popular culture depicts. Ankylosaurus is famous for their clubbed tail, which could break the bones of anything stupid enough to take one on. Ankylosaurus went extinct in the KT mass extinction, alongside most other animals it lived with.
In the park: Edit
We currently have three ankylosaurus. They reside in the Hell Creek Exhibit. There, they stay by themselves.
