Early Cretaceous crustacean microcoprolites from Sierra de la Cara Cura, Neuquén Basin, Argentina: Taphonomy, environmental distribution, and stratigraphic correlation

A new Early Cretaceous association of crustacean microcoprolites from the southern Mendoza sector of the Neuquén Basin, includes Palaxius salataensis Brönnimann, Cros and Zaninetti, 1972; Palaxius caucaensis Blau, Moreno and Senff, 1995; and Favreina cf. F.belandoi Fels, 1997. This microcoprolite as...
