Dino LessonThe two main types of Ankylosaur are the ankylosaurids and the nodosaurids. Aletopelta seems to bear resemblance both, suggesting that it is a basal member of one of these two groups. Like all ankylosaurs, Aletopelta was a bulky quadruped covered in armor-like osteoderms. Among these bony adornments, Aletopelta had two large spikes sticking up from the shoulder region of its back. It grew to an estimated 5 m in length, and weighed around 2 t.
