Abstract

Proterochampsidae are a group of predatory, putatively semi-aquatic, archosauriforms endemic to the Middle and Upper Triassic strata of Argentina and Brazil (Ischigualasto Formation and Santa Maria Supersequence). Here, the Brazilian species Proterochampsa nodosa from the Candelária Sequence (Santa Maria Supersequence of the Paraná Basin) is revisited with a detailed description, phylogenetic analysis and taxonomic revaluation. Through the application of computed tomographic scans, we were able to reveal part of the previously hidden morphology of its mandible and palate. We also discuss further differences between P. nodosa and P. barrionuevoi. The new phylogenetic analysis bolsters the monophyly of Proterochampsidae, the genus Proterochampsa and its position as the basalmost proterochampsid taxon in the clade.
