Sahil Alma (Lewis collection) (Cretaceous of Lebanon)

Also known as Sahel Alma

Where: Lebanon (34.0° N, 35.7° E: paleocoordinates 15.3° N, 31.0° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Late/Upper Santonian (85.8 - 83.5 Ma)

• The first dating of the section as "Senonian" by Fraas (1878) was refined by Ejel & Dubertret (1966) as Upper Santonian based on planktonic foraminifera.

• bed-level stratigraphic resolution

Environment/lithology: lithified lime mudstone

Size class: macrofossils

Preservation: soft parts

Collected by E.R. Lewis; reposited in the BMNH

• Specimens initially in collection of Prof. E.R. Lewis, Syrian Protestant College, Lebanon. Later transferred to the museum of Mr. Robert Damon at Weymouth, and many specimens later acquired by BMNH. Others at Royal Scottish Museum.
