Sphodrosaurus[1][2] is an extinct genus of basal Eosuchian reptiles from the Late Triassic-aged New Oxford Formation (not the Brunswick Formation as initially suggested) of Pennsylvania. The type species is S. pennsylvanicus, described by Edwin Colbert in 1960.[3] The holotype (NMN 2321; the cast is listed under AMNH 7601) consists of a partial skeleton including the back of the skull, the spinal column, all of the ribs, all of the hindlimbs and part of the upper forelimbs; Sphodrosaurus was originally believed to have been a member of the Procolophonidae and then a dinosaur,[3] while now Sphodrosaurus is believed to be a basal member of the Eosuchia, by most authors starting with Sues et al. (1993),[4], or a member of the Rhynchosauria (Baird, 1986[5]), although Rice et al. (2016) suggested it could have been a possible early stem-turtle (assumption based upon Sclerosaurus).[6]
