Abstract
ABSTRACT We describe a new taxon of lepidosauromorph reptile, Vinitasaura lizae, based on a nearly complete dentary and the posterior portion of a second dentary from the Upper Triassic (upper Carnian) Vinita Formation in east-central Virginia. It offers new insights into the morphological diversification and spatiotemporal distribution of lepidosauromorphs during the Triassic. The lepidosauromorph assemblage from the Vinita Formation include at least two other taxa and reveals connections to others in Europe and North America. It currently provides the best record of the early diversification of these reptiles in equatorial Pangaea, highlighting the potential importance of similar assemblages from still poorly sampled regions such as western North America for addressing questions concerning the origin and evolutionary history of this major diapsid clade during the Triassic.
