The postcranial skeleton of Neoaetosauroides (Archosauria: Aetosauria) from the Upper Triassic of west-central Argentina

The postcranial skeleton of the aetosaur Neoaetosauroides Bonaparte, based on previously studied specimens and additional material, is described herein. The new material consists of proatlas, cervical vertebrae, and appendicular dermal scutes collected in the Los Colorados Formation, Ischigualasto-V...
