A new species of the Late Triassic aetosaur Desmatosuchus (Archosauria: Pseudosuchia)

Comptes Rendus Palevol, 2005
Reanalysis of known armor of the stagonolepidid (aetosaur) Desmatosuchus has shown distinct differences in the lateral armor among individuals known from Carnian and Norian age rocks in the southwestern United States. Combined with previously reported cranial differences it is apparent that Norian specimens of Desmatosuchus represent a species distinct
