The best known of the Asian anklyosaurids, or armored dinosaurs, Pinacosaurus may have been a pack or herd animal at least in the juvenile stage as evidence has been found of several juveniles huddled together, apparently killed during a sandstorm.

The first anklyosaurs appeared in the early Jurassic Period in China and spread across every continent with the exception of Africa. These bulky herbivores reached their peak in the late Cretaceous when their bodies became much wider and some species even had armoured eyelids.
