Ankylosaurus
Ankylosaurids were armored dinosaurs. Their bodies were covered with bony plates called scutes (SKOOTS) that protected their bodies (except for the underbelly). They were quadrupeds, animals that walked on four feet. They were herbivores, or plant eaters.
Ankylosaurus (ang-KIE-low-SORE-uss) was the largest of this group. It grew to a length of thirty or more feet and was six feet wide. It may have weighed 13,000 pounds. Its armored body was wide and low to the ground. Ankylosaurus was built like a tank!
Its name means "fused lizard." It was named for the way many of its bones were fused together. At the end of its tail, some bony plates fused to form a bony club. This dinosaur used the club for defense against predators. Rows of spikes ran down its body, and it had small spiky horns on the sides of its head.
