Chrysochampsa is an extinct monospecific genus of alligatorine. Fossils have been found from the Golden Valley Formation of North Dakota and date back to the Wasatchian regional North American faunal stage of the early Eocene.[1] The genus has been proposed to be synonymous with Allognathosuchus at times,[2][3] but it is now generally accepted that Chrysochampsa is distinct from all other alligatoroids and is its own taxon.[4]
