Abstract

Fossil vertebrates from the Otis Chalk area of Howard County, Texas represent a diverse fauna of fishes, amphibians and reptiles. These fossils are from the Iatan Member of the Upper Triassic Dockum Formation. The presence of the phytosaur Paleorhinus indicates a late Carnian (early Tuvalian) age for the vertebrate fauna.
