Stratigraphy
| Formation: | Sespe | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: LITHOSTRATIGRAPHIC RELATIONS: From undifferentiated Sespe and Vaqueros Fms, which overlie the Santiago Fm (Eocene) and is overlain by the Topanga Fm (Middle Miocene). AGE: Late Eocene-Early Miocene, on the basis of vertebrate and molluscan biostratigraphy and stratigraphic correlations; most macrofossils come from the uppermost part of this undifferentiated unit and are suggested to be Early Miocene in age. | |||||
