MS-3-AM, Rio Maues (Devonian of Brazil)

Where: Brazil (4.0° S, 57.0° W: paleocoordinates 62.9° S, 33.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Protosalvinia zone, Curiri Member (Curua Formation), Early/Lower Famennian (376.1 - 370.6 Ma)

• member-level stratigraphic resolution

Environment/lithology: gray shale and micaceous, gray siltstone

• Niklas (1976, p.8): The sieze and shallow character of environments of deposition by mean of sedimentary structues of the calstic rocks and in terms such as tidal flat, delta, beach, shore and offshore rather than by supratidal, high intertidal, low intertidal and subtidal.
• Niklas (1976, p.7): The Maues core through the Protsalvinia Zone consisted of dark gray to brown or buff shale alternating with light gray to gray micaceous siltstone and fine sandstones heavily bioturbated vertically.

Preservation: adpression

Collection methods: core, mechanical,
