LATE TRIASSIC AETOSAUR BIOCHRONOLOGY REVISITED
Abstract—Eleven years ago Lucas and Heckert (1996) proposed five biochrons based on aetosaur genus-level occurrences in the Upper Triassic Chinle Group of the southwestern U.S.A., another for Stegomus in the eastern U.S.A., and a Greenlandic-European Aetosaurus biochron. While some have embraced thi...

No fewer than nine genera of aetosaurs provide biostratigraphic correlations within the Chinle Group, and five of these reliably correlate Chinle Group strata to other strata across Pangea.
