| Abstract |
Gastropods mollusck from Punta Maldonado Formation (Pliocene age) were collected and identified. The studied area is located in the Southern Pacific Coast of Mexico precisely in the Panamic Malacological Province. The taxonomy of the malacofauna are revised, the distribution in the Recent Age are analyzed and their precise location over time are recorded. Forty-nine species belonging to thirty-two genera are identified, from them three species: Conasprella armiger (Crosse, 1858), Solenosteira cf. dalli (Brown & Pilsbry, 1911) and Crepidula convexa Say, 1822 are part of the recent Caribbean Malacological Province while Enaeta barnesii (Gray, 1825) has not been previously registered for the Guerrero Coast. The distribution of the gastropods during the Pliocene shows the relics of the fauna before the closure of the Isthmus of Panama. |
