Late Emsian/Eifelian Loc. 19b of Melo: Picos region, Upper Pimenteira Formation (Devonian to of Brazil)

Where: Piaui, Brazil (7.0° S, 42.0° W: paleocoordinates 80.7° S, 4.6° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Pimenteira Formation, Emsian to Emsian (407.6 - 387.7 Ma)

• "Although the age of the [Pimenteira Fm.] is probably restricted to the Middle Devonian along the eastern outcrop belt [of which this locality is a part] its full range is Emsian through Famennian in the subsurface of central portions of the basin."

• member-level stratigraphic resolution

Environment/lithology: marine; sandstone and siltstone

• See lithology description.
• "The Pimenteira Fm. records the first widespread Devonian transgression over the Parnaiba Basin and conformably overlies the Itaim Mbr. It consists of interlayered sandstones and siltstones/shales mostly deposited as offshore bars or shelf sediments under the influence of storm generated waves and currents ("tempestites"), as indicated by the widespread development of large scale hummocky cross stratification throughout the section."
