Sebaa Chioukh Hills Reef, Tlemcen (Miocene of Algeria)

Also known as Reef 1979

Where: Algeria (35.2° N, 1.3° W: paleocoordinates 35.1° N, 1.6° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Messinian (7.2 - 5.3 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified limestone

• Several elliptical reef bodies, each approximately a kilometer in length and encased in argillaceous lime mudstones. Each step of reef building is represented by a tabular fringing reef with poor, but some, internal zonation. The whole sequence is about 50 m thick.

Size class: macrofossils
