Loc. N4, Río Copoma [Munguidó Fm] (Pliocene of Colombia)

Also known as Cucurrupi beds

Where: Colombia (4.3° N, 76.9° W: paleocoordinates 4.1° N, 76.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Munguidó Formation, Pliocene (5.3 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: From the "Cucurrupi beds", which de Porta (2003) refers to the upper Munguidó Formation, for which lithostratigraphic relationships are not reported. AGE: Miocene in Oinomkado, but referred to Pliocene by de Porta (2003). STRATIGRAPHIC POSITION: From unknown position within upper part of the formation.

• bed-level stratigraphic resolution

Environment/lithology: marine; poorly lithified, gray mudstone

• ENVIRONMENT: Shallow carbonate setting.
• SPECIFIC LITHOLOGY: Rather soft grey shale. LITHIFICATION: Poorly lithified, on the basis of facies description; may be unlithified, but figured specimens aren't available.

Size class: macrofossils

Preservation: original aragonite
