Amphiumidae indet.3 Gray 1825 salamander UALVP 14316 (incomplete left dentary). Originally reported by Naylor (1978), who believed the specimen came from the Bug Creek Anthills and referred it to Proamphiuma cretacea, but subsequent examination of the original accession record indicates it came from a Roche Percée locality (Gardner 2003)
Piceoerpeton willwoodense7 Meszoely 1967 salamander "Roche Perceé sites"; atlantes UALVP 11766-11772 and trunk vertebrae UALVP 11757-11765 (originally reported as “UA 14809-14815” and “UA 14800-14808”, respectively)
