Late Eifelian/Givetian Loc. 28 of Melo: Erepecuru River (Devonian of Brazil)

Where: Para, Brazil (1.0° S, 57.0° W: paleocoordinates 64.5° S, 32.6° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Erere Formation, Givetian (387.7 - 382.7 Ma)

• Collection not explicitly said to come from Erere Fmn., but this seems rather clear from stratigraphic and geographic context. See lithology description

• formation-level stratigraphic resolution

Environment/lithology: marine; micaceous siltstone and shale

• See lithology description.
• "The Erere Formation consists of micaceous siltstones with interbedded shales and sandstones and conformably overlies the Maecuru Fmn. Devonian invertebrates occur in all lithologic types...They are especially abundant in the lower Erere section and support the dominantly Givetian age indicated by microfossils...Along central and northern portions of the Amazon Basin the upper Erere Formation consists of relatively monotonous, laminated dark siltstones..." [radioactive shales also mentioned]
