A novel late Early Miocene assemblage of terrestrial gastropods from Santa Cruz (Patagonia, Argentina)
A remarkable fossil assemblage composed of five gastropod taxa is described from the Early Miocene of Santa Cruz (Patagonia, Argentina) in southernmost South America. The assemblage includes extinct and living genera South America, and on geographic distributions and represent background new informa...

A new taxon, Patagocharopa enigmatica n. gen. n. sp., is tentatively assigned to Charopidae. Gastrocopta patagonica n. sp. (Vertiginidae) represents the oldest record of Gastrocopta in Argentina and the southernmost record for the Americas. Punctum patagonicum n. sp. (Punctidae) represents the first record of Punctum for continental South America, and characterized by a protoconch with traces of axial costulae and a teleoconch with strong radial ribs. Zilchogyra miocenica n. sp. is the first Miocene record of the charopid genus Zilchogyra. Fragments of a possible Scolodonta (Scolodontidae) are recorded. Overall, the assemblage represents an important and useful paleoenvironmental tool. This fauna suggests that a more temperate and humid environment than today-with a more dense vegetation cover-was prevalent at this site during the Early Miocene. © 2016, The Paleontological Society. 2015 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00223360_v89_n5_p748_Miquel http://hdl.handle.net/20.500.12110/paper_00223360_v89_n5_p748_Miquel |
