Gour Lazib HGL10 (Eocene to of Algeria)

Also known as Locus 1 of Sudre (1975, 1979)

Where: Bechar region, Algeria (30.0° N, 4.0° W: paleocoordinates 24.4° N, 6.5° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: middle Member (Glib Zegdou Formation), Ypresian to Ypresian (56.0 - 41.3 Ma)

• Late early Eocene to lower Middle Eocene (Ypresian to basal Lutetian). Upper part of the detritic, charophyte-bearing formation as described by Sudre 1975. The exact correpondance between Sudre's original locus 1 and the level HGL10 is impossible to confirm, but the two sampling points are certainly very close if not equal.

• member-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; lenticular, intraclastic, red, yellow sandstone

• lenticular horizon of yellow to red sandstones containing rounded clay intraclasts and very rich in charophytes (oogones).

Size classes: macrofossils, mesofossils
