Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Aymamón Limestone (=Quebradillas Limestone of older works), which regionally overlie the Ponce chalky beds [subsequently referred to as Ponce Fm], and is laterally related to the Oak Grove Sands (Florida). AGE: Early-Middle Miocene based on macro- and microfaunal biostratigraphy in text. Here assigned to Middle Miocene based on more recent dating.
