Champsosaurus is an extinct genus of crocodile-like reptile, known from the Late Cretaceous and early Paleogene periods of North America and Europe. The morphology of Champsosaurus resembles that of gharials, with a long, elongated snout. It was native to freshwater environments where it likely preyed on fish, similar to living gharials.The skull of Champsosaurus is flattened, while the temporal arches are expanded posteriorly and laterally, giving the skull a heart shaped appearance when viewed from above. The body is flat and streamlined, with heavy gastralia (rib-like bones situated in the belly).Champsosaurus features teeth with striated enamel of the tooth crown with enamel infolding at the base. Anterior teeth are typically sharper and more slender than posterior teeth. The palatal teeth, likely in combination with a fleshy tongue probably aided in gripping and swallowing prey.Skin impressions of Champsosaurus have been reported. They consist of small pustulate and rhomboid scales, with the largest scales being located on the lateral sides of the body, decreasing in size dorsally, no osteoderms were present. AG015
