Abstract [en]

Here is reported fauna from a Middle Miocene limestone deposit of the Cojímar Formation near the town of Aguacate in the Province of Mayabeque, western Cuba. The fossils are preserved only as internal or external molds, but we identified members of at least eight bivalves and six gastropod families and one solitary coral. The most common taxon is a lucinid bivalve probably belonging to the genus Anodontia, which may likely represent a new taxon. This species in particular, and the fauna and facies in general, suggest that the Aguacate limestone may represent an ancient seagrass meadow environment. The fauna of the Aguacate quarry shows biogeographic relationships mainly to the Miocene of Panama and Florida, but also some links to the subtropical Atlantic coast of North America, and the Miocene of northern Ecuador.

Abstract [es]

Aquí se registra la fauna presente en un depósito de calizas del Mioceno Medio de la Formación Cojímar que aflorancerca del pueblo de Aguacate, en la provincia de Mayabeque, occidente de Cuba. Los fósilesse conservan solo como moldes internos o externos, peroidentificamosmiembros de al menos ocho familias debivalvos y seis de gasterópodos, y un coral solitario. El taxón más común es un bivalvo lucínido que probablemente pertenezca al género Anodontia, y que pudiera representar un nuevo taxón para la ciencia. Estaespecie en particular, y la fauna en general, sugieren que la caliza Aguacate puede representar un antiguoambiente de pradera de pastos marinos. La fauna de la cantera de Aguacate muestra relaciones biogeográficas principalmente con el Mioceno de Panamá y Florida, pero también algunos vínculos con la costa atlántica subtropical de América del Norte y con el Mioceno del norte de Ecuador.
