Also known as LACM 4611

Where: Acre, Brazil (10.9° S, 69.9° W: paleocoordinates 11.2° S, 68.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

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

• The outcrop is visible only in the low-water season and consists of an intraformational conglom- erate with clasts of clay and silt. It is part of a large paleochan- nel (Fig. 2). The base of the unit is not visible, and its upper part is covered by vegetation.

• formation-level stratigraphic resolution

Environment/lithology: alluvial fan; conglomerate and sandstone

• Latrubesse et al. (1997) interpreted the Solimoes deposits as being part of a megafan system, with its headwaters in the Peruvian Andes.
• The outcrop is visible only in the low-water season and consists of an intraformational conglom- erate with clasts of clay and silt.
