The large head is slightly flattened towards the rear and bears a large eye, pointed snout and long jaws, with a prognathic lower jaw. In the front of the upper jaw there are several fang-like teeth, then 4-5 sharp teeth which form a single row on the palatine followed by a single row of smaller teeth on premaxilla. The lower jaw has a single large canine-like tooth at its apex followed by a row of smaller sharp teeth along the each side of the jaw.
