'''''Bathygnathus''''' was a [[pelycosaur]]-grade [[synapsid]], a non-[[dinosaur]]ian amniote which lived during the [[Permian]] Period (about 270 Ma). The only specimen of ''Bathygnathus'' was discovered on [[Prince Edward Island]] during the course of a well excavation, in Spring Brook in the [[New London, Prince Edward Island|New London]] area and its significance recognized by the local naturalist [[Francis Bain]]. It was originally described by Leidy in 1855 as the lower jaw of a dinosaur. The specimen is now known to represent the upper jaw (maxilla) of a [[sphenacodontid]] synapsid.
