El Caucho farm (Cretaceous of Colombia)

Also known as Notoemys zapatocaensis type

Where: Colombia (6.8° N, 73.2° W: paleocoordinates 5.2° N, 42.1° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Synoceras verrucosum ammonoid zone, Rosablanca Formation, Late/Upper Valanginian (140.2 - 136.4 Ma)

• The locality is in a limestone layer belonging to the upper segment of the shallow marine Rosablanca Formation (Guzman 1985). The occurrence of the ammonite Saynoceras verrucosum (F. Etayo 2008, personal communication) indicates that this part of the Rosablanca Formation corresponds to the base of the late Valanginian stage (Early Cretaceous), approximately 138 Ma according to the biochronostratigraphic framework of Ogg et al. (2008).

• bed-level stratigraphic resolution

Environment/lithology: marginal marine; limestone

• shallow marine
• The locality is in a limestone layer

Size class: macrofossils
