PRE 06 (Miocene of Peru)

Also known as Ponto Rio Envira 06, Coqueiros

Where: Santa Rosa, Peru (8.3° S, 70.4° W: paleocoordinates 8.6° S, 68.7° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Solimões Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; conglomerate

• Briefly, the sedimentary sequence at sam- pling points A–C (Fig. 5B, C) comprises layers of grayish- green and red argillite, which are in erosive contact with the conglomeratic level very rich in fossil content. The con- glomerate is composed of carbonate concretions and numerous fossil fragments (such as remains of fishes, reptiles, and mammals, currently under study) supported by a silty-sandy matrix. This conglomerate is in direct contact with interca- lated layers of brown clay and very fine to fine yellowish sand (rhythmite).

Size classes: macrofossils, mesofossils, microfossils
