Stratigraphy
Local section:Loma del Viento
Regional section:Sucre
Stratigraphic resolution:bed
Stratigraphy comments: No lithostratigraphic nomenclature for these collections. Deposits of late Eocene age, referred to as Zone C. Correlatable on the basis of faunas to the Saman Formation and Chira Shales of Peru (upper Eocene to Oligocene) and upper Jackson Formation of the Gulf Coast, USA (Bartonian). The Eocene in the Sucre region of Columbia reaches 4,500 ft in thickness, of which the collections span the upper portion of Anderson's (1928) unit F (600 ft), near the top of this succession.
