It is identifiable as a therocephalian by its thin postorbital bar behind the eye socket, its elongated temporal opening behind the bar, and a thin lower jaw with a low coronoid process. Large tooth sockets in the upper jaw indicate that Yikezhaogia had large caniniform teeth. The teeth of the lower jaw are blunt-tipped and cylindrical.[2] Although its exact position among therocephalians is uncertain, Yikezhaogia is probably a basal member of the group Baurioidea.[1] References1. ^1 {{Cite journal | last1 = Abdala | first1 = F. | last2 = Rubidge | first2 = B.
