Basic Ankylosaurid
Info
Ankylosaurus
Ankylosaurus was an
armor-plated ornithopod from the Cretaceous of North America. With an
approximate lenth of 20 feet, Ankylosaurus was a dinosaurian battle
tank. The fused plates on its body offered protection from attacks while
its tail club may have been used as a bone-breaking defensive
weapon.
Edmontonia
A
member of infraorder Ankylosauris, family Nodosauridae, Edmontonia also
lived in Cretaceous North America. It was about the same size as
Ankylosaurus and also had body armor. Though it lacked a tail club,
its body was lined with large spikes. The spikes could have been used for
mating purposes, defense, or could have been a result of sexual
selection.
