Where: Morocco (34.0° N, 6.8° W: paleocoordinates 56.4° S, 22.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Pragian (410.8 - 407.6 Ma)

Environment/lithology: shallow subtidal; limestone

• -influenced by sea-level fluctuations.

•-well-preserved mudmounds.

•-the seafloor with numerous, up to 50 meter high mounds apparently created a broad range of habitats at Hamar Laghdad.
