Wadi Abu Hashim (Cretaceous to of Sudan)

Where: Sudan (20.0° N, 30.0° E: paleocoordinates 4.4° N, 24.7° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Wadi Abu Hashim Member (Wadi Milk Formation), Campanian to Campanian (84.9 - 66.0 Ma)

• Originally considered as Cenomanian, but now thought to be dated to the Campanian–Maastrichtian (Klein et al., 2016, and references therein)

• bed-level stratigraphic resolution

Environment/lithology: lacustrine - large; lithified siliciclastic sediments

• "..characterized by very fine-grained sandstone, siltstone, and claystone showing such sedimentary features as horizontal- or ripple lamination, calcretes and mottling (Rage and Werner, 1999:86)"

Size classes: macrofossils, mesofossils, microfossils

Collection methods: bulk, surface (float), surface (in situ), sieve,

• Collection derived from surface collection and screen washing of > 11 tons of matrix.
