Where: Colombia (11.1° N, 72.7° W: paleocoordinates 8.5° N, 59.3° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Manantial Formation, Selandian (61.6 - 59.2 Ma)
• From a bed 2 cm-thick, near the top of informal "Formation II" of Haught, Colley, and Belding (Tropical Oil Company), which is the Manantial Formation according to Etayo-Serna. Belongs to palynological zone T-02 to T-03a (Ayala et al. 2012), which are correlated with the middle Paleocene according to Jaramillo et al. (2011) on the basis of carbon isotopes.
• bed-level stratigraphic resolution
Environment/lithology: paralic; fine-grained, shelly/skeletal, calcareous sandstone
Size class: macrofossils
Preservation: mold/impression
