Unit 1 (Slama Stage), Bel Hacel, Algeria - Anderson (1936) (Pliocene of Algeria)

Where: Relizane, Algeria (35.8° N, 0.6° E: paleocoordinates 35.8° N, 0.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Slama Formation, Late/Upper Pliocene (3.6 - 2.6 Ma)

• The collection is from unit 1, a marly sand, 3 m thick, at the base of the 74 m thick section. The Mellah Stage of the Tellian Group is overlain by a thick marine formation composed of mostly dense argillaceous marl. The stage is thought to represent a considerable portion of the lower Pliocene. Its basal member is composed of conglomerate, which is then overlain by marl. The stage reaches up to 600 m in thickness. The Slama Stage is a middle member of the Pliocene strata and overlies an unconformity with the Tarhia Stage

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, yellow, blue, argillaceous sandstone

• No paleoenvironmental data reported.
• Tough, marly sand, grading down imperceptibly into gritty marl, and changing from yellowish to bluish with the downward gradation.

Size class: macrofossils

Collection methods: Unknown collector, probably the author.
