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
