Tupilakosauridae is an extinct family of dvinosaurian temnospondyls. It contains the genera Slaugenhopia, Thabanchuia, Tupilakosaurus, and possibly Kourerpeton.[1] Tupilakosaurs are known from Texas, Greenland, Russia, and France.[1][2] The earliest tupilakosaur, Slaugenhopia, is Early Permian in age while the latest known tupilakosaurs are Early Triassic in age. Derived tupilakosaurs possess embolomerous centra in their vertebrae, which are diplospondylous.[2] They also have a deep notch in the pterygoid bone of the palate.[1] Tupilakosaurs were aquatic, and used an undulatory mode of swimming much like that of eels.[2]
