Stratigraphic resolution:bed
Stratigraphy comments: Stated in text as being from "Miocene moyen et superior". Graham (1990) reports the Las Cahobas Formation as being Late Miocene in age based on floral microfossil biostratigraphy, while other authors (e.g. Van den Bold 1970, 1976) report a middle Miocene-Late Miocene age. The enterer (A. Hendy) assigns the Late Miocene age on the basis of most recent and confined age assessments.
