Fossil Decapod Crustaceans from the Jagüel and Roca Formations (Maastrichtian–Danian) of the Neuquén Basin, Argentina
Ten species of macruran, anomuran, and brachyuran decapod crustaceans, arrayed in eight families, were collected from seven localities in the Jagüel and Roca Formations, west-central Argentina. All of the decapods were collected from the Maastrichtian Jaqüel Formation and a part of the Roca Formatio...
