Diagnosis
ReferenceDiagnosis
D. A. Campos et al. 2011Diagnosis: Peirosaurid crocodyliform with the following combination of characters that distinguishes it from other members of this clade (autapomorphies are marked with an asterisk): posterolateral process of the squamosal thin and smooth*; postorbital with a comparatively acute anteromedial process*; anterior end of the frontal tapering between the prefrontals; dorsoventral extension of the lacrimal short (approximately 40% that of the orbit)*; anterior teeth thinner and more elongated than in other peirosaurids*; crowns that lack serrations; anterior teeth of the lower jaw inclined anteriorly; suture between the palatine and the maxilla V-shaped; presence of two alveoli couplets (6th–7th and 8th–9th pairs) in the mandible*
