Abstract

This paper describes the remains of the alligatorid from levels of the Piquete Formation (Pliocene-early Pleistocene) of Rosario de la Frontera, southern of Salta province, Argentina. The results of a phylogenetic analysis suggest a close relationship with species bearing a prominent rostral ridge of the genus Caiman Spix, being determined from their morphology that belongs to Caiman latirostris (Daudin). The validity of other remains assigned to the species is discussed, constituting this record the most complete and best preserved. Based on their ecological requirements are paleoenvironmental interpretations by analogy with the currently inhabited environment C. latirostris.
