La Cabrerita Lower Fossiliferous Horizon (Paleocene of Colombia)

Where: Socha, Colombia (6.0° N, 72.7° W: paleocoordinates 3.5° N, 60.0° W)

When: Arcillolitas de Socha Formation, Thanetian (59.2 - 56.0 Ma)

• We collected two samples of sandstones near the Carbonera Creek UR-03 (3° 22’ 12.71” N; 75° 8’ 56.07” W) and UR-04 (3° 22’ 12.21” N; 75° 8’ 51.89” W), which make part of the areniscas guía following Velandia- Angarita et al. (2023) (

Environment/lithology: lacustrine deltaic; claystone

• The Arcillolitas de Socha Formation is interpreted as a result of sedimentation in lagoonal, marshy, paludal, and deltaic environments

Size class: macrofossils

Collection methods: MAS, Museo de los Andes de Socha, Boyacá, Colombia;
