GI-I, Gara el Itima (Carboniferous of Morocco)

Where: Morocco (31.1° N, 3.7° W: paleocoordinates 21.4° S, 0.1° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Hamou-Rhanem Formation, Brigantian (336.0 - 326.4 Ma)

• basal Hamou-Rhanem Formation; Lusitanoceras - Lyrogoniatites ammonoid Genus-Zones.

•Heidelberger et al: Platygoniatites rhanemensis Assemblage – The co-occurrence of the genera Platygoniatites, Neogoniatites, Hypergoniatites, Dombarites, and Sudeticeras resembles faunas from the so-called Nm1a Zone of the South Urals (Ruzhencev & Bogoslovskaya 1971). This zone is situated below the entry of the genus Cravenoceras, and therefore, a late Brigantian age is most likely (Korn et al. 2007).

• group of beds-level stratigraphic resolution

Environment/lithology: basinal (); lithified shale

• monotonous shales

Size class: macrofossils
