Shale and Limestone at Taggourt-Izzem (Silurian of Morocco)

Where: Morocco (33.3° N, 5.5° W: paleocoordinates 66.9° S, 24.9° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Pridoli (423.0 - 419.2 Ma)

• "The presence of Scyphocrinites elegans suggests a possible Pridoli age for the limestone bearing this assemblage."

• formation-level stratigraphic resolution

Environment/lithology: marine; shale and limestone

• Some 500 km NW of Pridoli shoreline, according to paleogeographic map of ref. 7455.
• "limestone interbed with shale"
