"called out to the Geological Institute and then met first Dr. Burellarat, then Aguilera and Dr. Rize. The two younger men told me into the exhibition room of fossils and explained to me the collections. Dr. Benellarat showed me through marine Triassic fauna or far modeled out or maybe discovered. It consists entirely of Paldeoneilo, a new genus of pelecypod Cassianella and an ammonite (see the Bulletin de presented to me). The Cassianella in general form and especially in preserva- tion look like Cretay fossils. If it were not for the ammonite one would have called this fauna Devonian. The locality is Jacateros which we will visit on our southern excursion. Then Dras showed the upper Jurassic faunas. These go with out break into the Cretaceous. Nearly all the correlations with Europe are based on Ammonites and both Burellarat and Rize said that unless these fossils are present no reliable correlation can be made. Then both gentlemen let loose on Stanton's
