Cerrejón Formation 0712 (Paleocene to of Colombia)

Also known as 0712

Where: Colombia (11.1° N, 72.6° W: paleocoordinates 8.5° N, 59.5° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Foveotricolpites perforatus pollen zone, Cerrejón Formation, Middle Paleocene to Middle Paleocene (61.7 - 55.8 Ma)

• bed-level stratigraphic resolution

Environment/lithology: "channel"; lithified, silty, sandy siliciclastic sediments

• We collected fossil leaves and fruits from six lens-shaped, siltstone/sandstone bodies with inclined heterolithic strata that suggest deposition in low-energy channels. Ten other localities preserve leaves in thin but tabular beds of flat- laminated siltstone that indicate deposition in small lakes. The megafloral local- ities occur from 100 –750 m above the base of the formation

Size classes: macrofossils, mesofossils, microfossils

Preservation: adpression

Collection methods: bulk, quarrying, mechanical,
