Masato Site (Miocene of Colombia)

Where: Huila, Colombia (3.2° N, 75.2° W: paleocoordinates 2.6° N, 72.6° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Villavieja Formation (Honda Group), Laventan (13.8 - 11.8 Ma)

• The Honda Group exposed in La Venta consists of three formations: the Cervatana, Villavieja and Las Mesitas Formations (in ascending order). Most of the primate and other mammalian fossils have been obtained from the Villavieja Formation, which consists of alternating beds of claystone, silt stone and sandstone. The Villavieja Formation is subdivided into four members: the Molina, Los Mangos Red, Las Lajas and Tatacoa Red Members (in ascending order). The “Monkey Unit” of Fields (1959), which is very famous for yielding many primate fossils, corresponds to the lower part of the Molina Member. The present materials were recovered from the Masato Site, which corresponds to the lowest part of the Tatacoa Red Member.
