Also known as LACM 5158

Where: Pando, Bolivia (10.8° S, 69.8° W: paleocoordinates 11.1° S, 68.1° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Acre Conglomerates Member (Solimoes Formation), Huayquerian (8.0 - 5.0 Ma)

• The authors redefine both the Solimoes and the Madre de Dios formations indicating that the Acre Conglomerates Mbr. is not the lowermost member of the latter formation but the uppermost one of the Solimoes formation, changing the age of this member from Pleistocene to late Miocene based on the presence of land mammals of this age.

•The fauna is of Huayquerian age (Frailey (1986).

• member-level stratigraphic resolution

Environment/lithology: lacustrine - large; pebbly, muddy conglomerate and siltstone

Size class: mesofossils
