Thyreophora includes Stegosauria (like the armored "Stegosaurus") and Ankylosauria (like "Ankylosaurus"). ILM also designed some dinosaurs entirely through CGI, including "Ankylosaurus" and "Brachiosaurus". He transforms into an "Ankylosaurus" and was recolored into Dinobot Slapper. Like other ornithischians, "Ankylosaurus" was herbivorous. The osteoderms of "Ankylosaurus" were generally thin walled and hollowed on the underside. Their phylogeny includes some uncertain phylogenetic relationships, between "Ankylosaurus", "Anodontosaurus", "Scolosaurus", and "Ziapelta". Many genera are included in the clade, such as "Ankylosaurus", "Pinacosaurus", "Euoplocephalus", and "Saichania". One day Heart discovers an egg which houses an "Ankylosaurus". Second Ankylosaurus to appear in the series. The clade was defined to include "Ankylosaurus" and Acanthopholinae. The position of the orbits of "Ankylosaurus" suggest some stereoscopic vision. Ankylosaurines are defined as being closer relatives to "Ankylosaurus" than to "Shamosaurus". Compared to "Euoplocephalus", the osteoderms of "Ankylosaurus" were smoother. One ankylosaurian and two nodosaurians are known, "Ankylosaurus", "Denversaurus" and possibly "Edmontonia". In 2002, a genus of ankylosaurus, "Crichtonsaurus" was named in his honor.
