This vomerine tooth was found by Dr. D. R. Kannemeyer when resident at Burghersdorp. It is the only evidence of the dentition of the animal known, and is interesting as being of much larger size than any Labyrinthodont teeth hitherto found in South Africa, though smaller than the large teeth of Mastodonsaurus giganteus from the Keuper of Würtemburg. Its presumed position on the palate is based upon the anchylosis of the tooth with a bone which shows a flat oblique suture at the base of the crown. This sutural surface is usual on vomerine teeth, and indicates that the tooth was directed downward, outward, and a little backward.
