as two large meckelian fenestra (holes visible on the inner surface of the jaw), but it also has a few unique and diagnostic traits. It was approximately 34.2 cm (13.5 in) long, deep towards the rear and tapering and curving upwards towards the front. However, the rear portion of the jaw is not as deep as in the European embolomeres. This is because the surangular bone, which forms the upper portion of the jaw behind the tooth row, was only gently convex along its upper edge, rather than strongly arched with a pronounced crest. The outer surface of the jaw has an pronounced lateral line canal which becomes more indistinct towards the jaw joint. Like the rest of the skull, tooth preservation on the jaw is too poor to conclude much about its dentition. However, it is clear that the first of the coronoids (a series of bones adjacent and inwards of the main tooth row) was toothless, in contrast to Eobaphetes and Eogyrinus, which have denticles on the first coronoid.
