The holotype is the anterior portion of the left mandible, from the symphysis to the splenial bone and containing portions of the coronoid. Teeth number 9 to 15 are intact, with the eighth being a partial tooth and none of the other remaining past the mandible. The teeth slightly enlarge from anterior to posterior.
