The Ankylosaurus is not one of the most famous dinosaurs, but it might be one of the coolest! While the Ankylosaurus only ate plants, it had a tail that was like a big club, and its body was covered in armor! In fact, the Ankylosaurus is sometimes called the tank of dinosaurs.
Its tail could break bones with a single strike, and it definitely helped keep the Ankylosaurus safe from the other dinosaurs who were looking for dinner.
While the Ankylosaurus was pretty long (about 20 or 30 feet!), it stayed low to the ground and gathered food that was easy to find and easy to chew.
