Tendaguru quarry M 1 (Jurassic of Tanzania)

Also known as British Expedition, Ditch 3X, Ditch III

Where: Lindi, Tanzania (9.7° S, 39.2° E: paleocoordinates 29.9° S, 17.0° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Upper Dinosaur Member (Tendaguru Formation), Tithonian (152.1 - 145.0 Ma)

• 2 strata with bones; formerly Upper Saurian Bed

• group of beds-level stratigraphic resolution

Environment/lithology: estuary or bay; gray, conglomeratic claystone and sandstone

• "a pool in the bed of a river which flowed only during part of the year"

This stratum was very wet, and rested on a dark grey, nearly black, clay, also full of moisture, and which emitted a very bad smell when opened up after perhaps millions of years' burial." (Migeod 1928). "laminated grey grit on sand" (Migeod 1931)

Size classes: macrofossils, mesofossils

Collected by W. Cutler & F. W. H. Migeod in 1926, 1929; reposited in the BMNH
