Gour Iduka type sect., Ouan Kasa Fmn., Samples RB311 & OB857 (Devonian of Libya)

Where: Libya (27.0° N, 10.0° E: paleocoordinates 58.9° S, 46.5° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Ouan Kasa Formation, Emsian (407.6 - 393.3 Ma)

• Formation spans much of Lower Devonian. Samples interpreted as Emsian on basis of Styliolina uralica in a close level (sample UB331).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; sandstone and shale

• Interpreted as BA2-3 nearshore with moderate currents.
• Formation as a whole: "sandstones and shales". Shells in coquinites or on bedding planes.

Collection methods: Emphasis of monograph is brachiopods and bivalves. Other elements sometimes mentioned as well.
