The longest Ankylosaurus Top 10. Dimensions of Ankylosaurus

Length, dimensions, size of ankylosaurus

The Ankylosauria – a group of four-legged, herbivorous dinosaurs, which were characterized by armor made of bone plates. They appeared in the Middle Jura , but peaked in the Cretaceous period where they became widespread worldwide. They have been found on every continent. Most Ankylosaurs reached lengths of four to six meters, the largest representatives like Ankylosaurus became up to 8 meters long, while the smallest representatives like Struthiosaurus and Minmi only reached three meters. All Ankylosaurs had a broad, stocky trunk with four short, strong limbs. They only moved on four legs. The hind legs were longer than the front legs, which brought the head to a position close to the ground.

Many representatives of the Ankylosauridae, but not the Nodosauridae, had a bony club at the tip of the tail. This consisted of osteoderms that were overgrown with the vertebrae and was supported and stiffened by ossified tendons.

Today we present the world’s largest list of ankylosaurs ranked by length. Soon we will present a list of the heaviest Ankylosaurus.
