ABSTRACT
Three species of lower Eocene ostreids are reported from the Viento Formation of the La Popa Basin, Nuevo Len, 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.
