Mymoorapelta ("Shield of Mygatt-Moore") is an ankylosaur from the Late Jurassic (Kimmeridgian-Tithonian) Morrison Formation (Brushy Basin Member) of western Colorado. The taxon is known from portions of a disarticulated skull, parts of three different skeletons and other postcranial remains. There is presently some controversy as to this ankylosaur's position within the Ankylosauria. Vickaryous et. al. (2004) considered it Ankylosauria incertae sedis, while Kirkland et Carpenter (1994) placed it within the Family Polacanthidae. To date, only a single species has been named for this taxon, M. maysi. Along with Gargoyleosaurus pankinorum, Mymoorapelta is one of the earliest known ankylosaurs, providing a look at the early evolution and diversification of this group of dinosaurs.
