Late Emsian/Eifelian Loc. 15 of Melo: Well 1-CL-1-MA, 856-990 meters (Devonian to of Brazil)

Where: Maranhao, Brazil (7.0° S, 48.0° W: paleocoordinates 78.6° S, 27.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Emsian to Emsian (407.6 - 387.7 Ma)

• Based on stratigraphic charts and discussion in text, this would likely be the equivalent of Pimenteira Fm.

Environment/lithology: marine; siliciclastic sediments

• Reflects deepening relative to underlying Serra Grande Formation (deltaic complex).
• The Late Emsian/Eifelian sequence in the Parnaiba Basin consists of shales, silts, and sands.
