Where: Tolima, Colombia (4.3° N, 75.1° W: paleocoordinates 1.1° N, 44.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Late/Upper Aptian (122.5 - 113.0 Ma)

• On the basis of the presence of the genus Cheloniceras, it is believed that this outcrop is of upper Aptian age. This age is broadly corroborated by the finding of the ammonite Douvilleiceras about 2 kilometers downstream (higher stratigraphically).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified shale

Size class: macrofossils

Preservation: cast

Reposited in the UCMP
