Species: T.‭ ‬ruthae‭ (‬type‭)‬.

       Most study about Tarjadia so far has been concerning the osteoderms‭ (‬sometimes called scutes‭)‬,‭ ‬pieces of bone that resided within the skin.‭ ‬The osteoderms of Tarjadia are very distinctive in that they have heavy pitting on their surface.‭ ‬These osteoderms likely afforded Tarjadia a fair amount of protection from other predators of the time such as rauisuchians and other kinds of archosaurs,‭ ‬perhaps even the ancestors of the dinosaurs.
       Identified as a doswelliid,‭ ‬Tarjadia was related to Doswellia and Archeopelta.‭ ‬Like these,‭ ‬Tarjadia is thought to have possibly been predators of smaller animals.
