Oiti (= Oitis) (Devonian to of Brazil)

Also known as Late Eifelian/Give. Loc. 22 of Melo: Oitis and Ponta de Serra region

Where: Piaui, Brazil (6.3° S, 41.5° W: paleocoordinates 74.6° S, 8.0° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Pimenteira 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. PJW: Caputo & dos Santos (2020) note that this is now Pimenteira formation.

• 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 fauna...is restricted to its lower section (Passagem Member), as mostly associated to storm beds."

Size class: macrofossils
