[1] In February of 2001 the Museo Carmen Funes conducted a joint expedition with the Royal Tyrell Museum at the Sierra Barrosa Locality, 30km north-east of Plaza Huincul, Neuquén province.

There the team uncovered the bones of dinosaurs and mammals, bird footprints and notably a nearly complete peirosaurid fossil from the Bajo de la Carpa Formation.

[1] The holotype, MCF-PV 413, was found lying on its ventral side, the skull articulated with the remaining skeleton which consisted of both forelimbs, most of the vertebral column up to the sacrals, one hindlimb and semi-articulate osteoderms that obscured parts of the fossil.

[1] The generic name derives from the Sierra Barrosa locality where the fossils have been found and the Ancient Greek: σοῦχος, romanized: souchos, (soukhos) meaning crocodile.

[1] The skull of Barrosasuchus is nearly complete, articulated with the lower jaw and the cervical vertebrae and measures a total of 315 mm, slightly smaller than the specimens known from Lomasuchus and Gasparinisuchus.

The entire skull is tubular in shape and moderately wide, heavily ornamented with pits and grooves of varying arrangement and density.

It is based on the character-taxon matrix of Pol et al. (2014), incorporating many of its daughter matrices that had been created parallel to one another into a single phylogenetic tree.
