Bou Nemrou echinoderms, Zagora Lc2 (Ordovician of Morocco)

Also known as Locality 2 of Sumrall and Zamora, 2011

Where: Anti Atlas, Morocco (30.6° N, 6.0° W: paleocoordinates 81.9° S, 92.8° E)

• coordinate estimated from map

When: Upper Member (Izegguirene Formation), Dobrotivian (459.0 - 457.9 Ma)

• Izegguirene Formation. Possibly Izegguirene Formation, earliest Caradoc (Dobrotovian), ECR-F4. Echinoderms from this level suggest a probable Dobrotivian age (B. Lefebvre pers. comm.), either latest Darriwilian or earliest Sandbian

Environment/lithology: coastal; concretionary sandstone and siltstone

• fine sandstones intercalated with millimetre-scale drapes of siltstone

Size classes: macrofossils, mesofossils

Preservation: cast, mold/impression
