Abstract
The first evidence of a crocodyform on the Futalognko quarry (Neuquén, Argentina) is presented. The Portezuelo Formation has given in this site an extraordinary fossil record.  The more impressive materials correspond to Sauropod, theropod and ornithopod dinosaurs.  However; it is also important the evidence of turtles, pterosaurus, crocodiles, fish and plants. In this paper we describe a crocodilyform tooth that is assigned to the Peirosauridae family, probably to Lomasuchus palpebrosus. The tooth comes from the Portezuelo Formation. Two more crocodilyforms are known from the area: Lomasuchus palpebrosus herein referred to the Portezuelo Formation (upper Turonian – lower Coniacian) and Peirosaurus tormini assigned to the Bajo de la Carpa Formation (upper Coniacian).
