Deltasuchus ("delta crocodile") is a genus of neosuchian crocodyliform from the Late Cretaceous of Texas, specifically in the Woodbine Formation, which was a part of the Appalachian continent during the Cretaceous. It is known from one species, D. motherali, named in 2017 by Stephanie Drumheller, Thomas Adams and Christopher Noto.[1] It was a large crocodyliform with an estimated total body length of more than 5 metres (16 ft).[1] In 2021, new material was described, allowing Deltasuchus to be placed within the family Paluxysuchidae as the sister taxon to Paluxysuchus,[2] and it was highligted that juveniles possessed a slenderer snout, indicating an ontogenetic broadening of the skull as the animal grew. It possessed a pair of enlarged canine-like teeth on each side of the lower jaw (corresponding to the 3rd and 4th tooth of each dentary).
