Three species of lower Eocene ostreids are reported from the Viento Formation of the La Popa Basin, Nuevo León, northeastern Mexico. Two of them are described as new: Ostrea (Turkostrea) ventosa new species, and Ostrea (Turkostrea) ovata new species. Ostrea sp. is also reported associated with the new forms. The large size of these species, in contrast with their small relatives from equivalent depositional environments in the underlying Adjuntas Formation, suggests that paleoclimate played an important role in their size development. These ostreids are the youngest fossils reported from the La Popa Basin, as the Viento Formation has remained undated prior to this contribution. The age suggested for the Viento Formation corresponds to the early Eocene, probably the upper part of the Ypresian.

The Circum-Gulf of Mexico and the Caribbean: Hydrocarbon Habitats, Basin Formation and Plate Tectonics
The Circum-Gulf of Mexico and the Caribbean has long been one of the world's most important petroleum provinces, as well as one of the world's most geologically complex regions. These two characteristics have resulted in an extensive amount of ongoing research by both industry and academia. AAPG Memoir 79, The Circum-Gulf of Mexico and the Caribbean, is the first volume in more than a decade to document such a wide range of research on the geology of this vast area. Of the total 44 papers, roughly two-thirds pertain to the Gulf of Mexico, with an emphasis on the Mexican portion of the basin, and to the petroliferous areas of the southern Caribbean, including Colombia, Venezuela, Cuba, and Trinidad and Tobago. The remaining papers relate to the Antilles and Central America, as well as a series of papers that address region-wide topics such as plate tectonic evolution. A significant number of papers were contributed by authors from national oil companies and universities from within the region.
