Scolomastax ("Pointed jaw") is a genus of crocodilian from the Late Cretaceous Arlington Archosaur Site in the Woodbine Formation near Dallas, Texas. It was about three to six feet in length and its right lower jaw had fewer teeth than related crocodilians, with those teeth coming in several different shapes. The shape and number of the teeth of this genus suggest that it may have been omnivorous, as these traits are commonly seen in living animals that crunch on hard food or eat a varied diet. Scolomastax is classified as a paralligatorid, a group best known from Asia, making it the first member of the group ever found in Appalachian deposits. This suggests that animals in Asia and North America intermingled in the early Cretaceous before the Western Interior Seaway split North America in two.
