Fun Facts: 

A healthy adult Ankylosaurus probably had few predators, if any, despite living alongside the
biggest predator in North America – Tyrannosaurus rex.

Their defensive strategy likely consisted of staying as close to the ground as possible to
avoid being flipped over, and wielding a formidable tail club.

Its leaf or spade-shaped teeth were probably useful for stripping leaves from plants, but not
for chewing.

Brain Size

How big was Ankylosaurus' brain? 

The name Ankylosaurus, meaning "fused," or :stiffened lizard," refers to the many fused bones in the skull and tail of this dinosaur. These fused bones strengthened the skeleton, presumably to protect it from the predators. 

All of this thickened, fused skull material left little room for a brain. Anklyosaurs may have been almost as long as a bus (and maybe heavier!) but its brain was only slightly bigger than a walnut. Ankylosaurs probably weren't the rocket scientists of the dinosaur world!
