pholidosaur features and has a robust tubular and slightly flattened rostrum widening abruptly around the jugals. The nasals are separated from the nares by the premaxilla, which tapers at its posterior end and extends far between the maxilla, and the supratemporal fenestrae are moderately sized, making up 25% of the skull table, differing from

In the early 2000s another locality of the Phu Kradung Formation was discovered near the village of Kham Phok, Mukdahan Province, yielding amongst other remains the anterior tip of a crocodylomorph mandible which was assigned to 538:
The holotype mandible is very robust, and its tip is spoon shaped and wider than the portion of the jaw immediately behind it. The mandible of PRC102-143 is similar in size, though less complete, and preserves the same spatulate appearance. The 3rd and 4th dentary alveoli are raised and contiguous

The referred cranial material suggests a possible skull length of 1.1 m (3 ft 7 in). The complete animal could reach over 10 m (33 ft) in body length, although other estimates suggest 7–8 m (23–26 ft). The specimen shows a combination of goniopholidid and
