The Scoop

Bony Plates, Spiked Tail

The Ankylosaurus inhabited the woodlands of North America during the late Cretaceous Period which existed between 70 and 65 million years ago.  During this time, the Western United States had a warm, humid, near-tropical climate. This dinosaur can be compared to an armored car as it was low-slung, slow-moving, and covered with thick, nearly impenetrable armor. For protection from its enemies, these dinosaurs developed tough, scaly body armor, as well as spikes and bony plates. Some had dangerous clubs on the ends of their long tails that they swung at approaching carnivores.

The name Ankylosaurus is Greek for "fused lizards”. These dinosaurs were huge- around 30 feet in length, which is as long as or a little longer than a bus. They weighed around 5 tons or more. In spite of their impressive size, they were plant eaters.  They spent their days grazing on low-lying vegetation. The Ankylosaurus had a beak and small teeth, which it used to browse on large quantities of plants.  Though these dinosaurs had very few animals preying on them, the Ankylosaurus populations slowly but surely died out 65 million years ago.
