DV 631-12 [Chilcatay Fm]DeVries T. J. (2007)ChilcataySTRATIGRAPHIC RELATIONS: From the Chilcatay Fm, which regionally, unconformably overlies the Otuma Fm (Oligocene) and is unconformably overlain by the Pisco Fm (Middle Miocene-Late Pliocene). AGE: latest Oligocene-early Middle Miocene, for which justification is not stated. Overlain by the Prisco Fm, for which K/Ar dates, siliceous microfossil zonation, and molluscan biostratigraphy supports a Middle Miocene age at its oldest. The collection is placed by the authors within the uppermost Oligocensandstone28.4 - 23.03 Ma

DV 631-8 [Paracas Fm]DeVries T. J. (1998)ParacasSTRATIGRAPHIC RELATIONS: From the Paracas Fm, which regionally, unconformably, overlies crystaline bedrock and us unconformably overlain by the Otuma Fm (latest Eocene to Early Oligocene). AGE: Late Eocene in text, on the basis of K/Ar dates, siliceous microfossil zonation, and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From unknown position within formation.sandstone37.2 - 33.9 Ma
