Where: Morocco (33.2° N, 5.6° W: paleocoordinates 50.5° S, 22.3° E)
• coordinate based on political unit
• local area-level geographic resolution
When: Nowakia holynensis other zone, Akrech Formation, Emsian (407.6 - 393.3 Ma)
• PJW: Was Eifelian, but Unitary Analyses makes Anarcestes lateseptatus late Emsian, which is also consistent with the Nowakia holynensis zone noted by Jell & Adrain (2002). Given area, it is probably the Akrech formation.
• formation-level stratigraphic resolution
Environment/lithology: marine; marl
Size class: macrofossils
