Abstract: Here we establish the stratigraphic and geographic provenance of the "Belodon" buceros Cope. The holotype, originally collected by David Baldwin in 1881, is an incomplete phytosaur skull discovered near "Huerfano Camp" in north-central New Mexico. This skull is the first phytosaur skull described from the American West, and its precise provenance has never been established. Baldwin's use of the term Huerfano Camp may refer to Orphan Mesa, an isolated butte just south of Arroyo Seco. Fossils collected by Baldwin, and our subsequent collections from Orphan Mesa, are from a fossiliferous interval high in the Petrified Formation of the Chinle Group. These strata yield a tetrapod fauna including the aetosaur Typothorax coccinarum and the phytosaur Pseudopalatus, both index taxa of the Revueltian (early-mid Norian) land-vertebrate faunachron. "Belodon" buceros is correctly referred to Pseudopalatus buceros (Cope) and is an index taxon of the Revueltian land-vertebrate faunachron.
