Stratigraphy comments: LITHOSTRATIGRAPHY: From the Culebra Formation, which unconformably overlies the Las Cascadas agglomerate; reassigned to La Boca Fm in subsequent publications of Woodring (e.g., 1973, 1982), but further emended by Kirby et al. (2009) to the lower member of the Culebra Formation. AGE: Early Miocene in text; direct date extrapolated from Kirby et al. (1999), =Aquitanian.
