 At the anterior end the premaxillae come together in a short triangular projection pointing ventrally and in another pointing dorsally.These would have been connected by a cartilaginous septum separating the two external nares, although this has not been preserved.The premaxilla bears two incisiform teeth and one caniniform tooth; this has led some to place it in the sphagesaurid group of crocodyliforms, since these also had differentiated teeth, although as the cladogram below suggests this is disputed.
