Resumen:
Proterochampsia is a monophyletic group of crocodile-like archosauriforms currently
endemic to the late Middle and early Late Triassic of South America considered as one of the
potential successive sister-taxa of the crown group Archosauria. The proterochampsians come
from the Ischigualasto-Villa Unio´n Basin in the west of Argentina and the Parana Basin in the
south of Brazil. The traditional composition of the group includes the genera Cerritosaurus
Price 1946, Proterochampsa Reig 1959 (with two species: P. barrionuevoi in Argentina and
P. nodosa Barberena 1982 in Brazil), Chanaresuchus Romer (with two species from Argentina:
C. bonapartei Romer and C. ischigualastensis Trotteyn et al. 2012), Gualosuchus reigi Romer
1971 and Tropidosuchus romeri Arcucci 1990. After a precladistic history of confusion about
their relationships with crocodilians, in the last 20 years new discoveries of taxa, and more systematic
and phylogenetic studies, have clarified their position as non-archosaurian archosauriforms
and their relationships with other Triassic archosaurs.
