Loc. G - Wadi Barak [Nimra Limestone] (Cambrian of Israel)

Where: Israel (29.8° N, 34.7° E: paleocoordinates 32.7° S, 141.7° E)

• outcrop-level geographic resolution

When: Nimra Formation, Lenian (516.0 - 513.0 Ma)

• The brachiopods occur in a layer 3 meters below the top of the Nimra Formation. The formation commonly wedges out, but has an overall sharp contact with the overlying formation. The international stage name is derived by the following equivalence: Issafenian = Bilbilian (Spanish) = Lenian. In addition, the end of the Bilbilian stage is determind by the beginning of the Eccaparadoxides zone corresponding to the end of the Lenian as interpretted by Dr. D. C. Fernandez Remolar of the Center of Astrobiology, Madrid, Spain. URL: www.cab.inta.es/2_Inv_CAB/23_Documentos/Papers1.html

• bed-level stratigraphic resolution

Environment/lithology: lithified, gray, sandy dolomite

• the nimra formation has a thickness between 0-21.5 meters and consists of well bedded, sandy to gritty, grey, reddish to pink, locally manganiferous and cupriferous dolomite with large salt casts.

Preservation: replaced with silica

Taxonomic list

• COVERAGE: Exhaustive for most brachiopods, with occasional characteristic trilobites. The taxonomic list does not include obloid fossils lost in the dissolving process (most abundant at locations A and B). NOMENCLATURE: Authoritative publication, with fairly modern nomenclature and species-resolution identifications where available.
