Nuevo registro fósil de aturia cubaensis (lea, 1841) [cephalopoda, nautilidae] para el mioceno inferior - medio de Costa Rica

[摘要] A new specimen of Aturia fossil was collected from sublitoral or shallow marine sedimentary sequences of the Lower- Middle Miocene Roca Carballo Formation at the Central Pacific coast, in the Puntarenas province, Costa Rica. As result of the taxonomic study of the fossil, it is confirmed that this specimen corresponds to Aturia cubaensis (Lea, 1841), based on the shell shape and in major features of its sculpture. This is the second time that this species is recorded for the Miocene of South Central America and some stratigraphic inferences about the first found at the Río Banano Formation are made.
