Ankylosaurus Armor Quiz – Osteoderms and the Tail Club

Ankylosaurus lived in western North America near the end of the Cretaceous, about 68 to 66 million years ago. It was one of the largest armored dinosaurs, with a wide, low body.

Its back was covered with osteoderms, bony plates set in the skin, and its head was armored too. The tail ended in a heavy club of fused bone, held stiff by interlocking vertebrae like a handle.

It ate plants with small leaf-shaped teeth. Barnum Brown named it in 1908, and its name means fused lizard, a nod to its fused bones.
