Delphinognathus is an extinct genus of Tapinocephalidae. Its fossils have been found in the Karoo Beds in Cape Colony, South Africa.[1] It was first named by Professor Harry G. Seeley in 1892, and contains one species, D. conocephalus. Seeley described the animal on account of a skull specimen, which had been discovered by Cape Colony government geologist Thomas Bain.[2] Although the skull had apparently suffered from poor preservation, he declared it indicative of a new family of fossil reptile.[2] Delphinognathus is the only Tapinocephalid in which the orbit of the skull lies wholly in the posterior half.[3]
