Coordinates: 11.9° North, 71.3° West (view map)
Paleocoordinates:12.6° North, 66.8° West (Wright 2013)
Basis of coordinate:unpublished field data

Stratigraphy
Formation:Castilletes Member:middle Castilletes
Local section:Yotojoro Local bed:21 m
Local order:bottom to top
Regional section:Cocinetas Regional bed:131 m
Regional order:bottom to top
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware Formation. This area and nearby collections have been previously mapped as Castilletes Formaton (late Pliocene-early Pleistocene). AGE: Langhian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From approximately 131 m in regional section.
