Late Eifelian/Give. Loc. 23 of Melo: Pedro Segundo Ridge (Devonian to of Brazil)

Where: Piaui, Brazil (4.0° S, 42.0° W: paleocoordinates 72.4° S, 5.6° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Cabecas Formation, Eifelian to Eifelian (393.3 - 382.7 Ma)

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

• formation-level stratigraphic resolution

Environment/lithology: marine; sandstone

• See lithology description.
• "The Cabecas Formation is a thick, progradational sandy unit resembling the Chapada unit no. 3 of the Parana Basin due to its massive appearance and monotonous development of sigmoidal lobes. It often displays synsedimentary slumping structures and is locally cut through by wide, shallow channels. The fairly abundant marine restricted to its lower section (Passagem Member), as mostly associated to storm beds."
