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. ==References== * [http://www.dinosauria.com/dml/genera.htm DML Dinosaur Genera List] {{portalpar|Dinosaurs}} [[Category:Sphenacodonts]] [[Category:Permian synapsids]] [[Category:Prehistoric synapsids of North America]] {{paleo-stub}} [[ru:Батигнат]]
