Abstract: Fragmentary fossils collected by one of us (NH) from the Upper Triassic Popo Agie Formation
represent the first occurrence of the rhynchosaur Hyperodapedon in the Chinle Group. The Wyoming
record is of Otischalkian (Late Triassic: late Carnian) age. Globally, Hyperodapedon occurrences
define a Hyperodapedon biochron of late to latest Carnian (Otischalkian-Adamanian) age for strata in
North America, Scotland, India, Tanzania, Zimbabwe, Madagascar, Argentina, and Brazil. This resolution is coarser than that achieved using other taxa, principally phytosaurs and aetosaurs, but helps to correlate strata in which these taxa are rare or absent.
