Bir Abu Ben, section 5/85 (Location 4) (Cretaceous to of Sudan)

Where: Northern, Sudan (17.3° N, 30.9° E: paleocoordinates 0.8° S, 24.6° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Wadi Howar Formation, Coniacian to Coniacian (89.8 - 83.6 Ma)

• "probably equivalent" to this formation. Footprints in "Unit I2"

• bed-level stratigraphic resolution

Environment/lithology: crevasse splay; bioturbated siltstone and fine-grained sandstone

• low-energy deposition, "overbank deposits of a low-sinuosity fluvian environment or associated fluvio-lacustrine sub-environments"
• Unit I2: "fine-grained sandstone, horizontally bedded and ripple cross-laminated. Tetrapod footprints occur on the interface of the intercalating bioturbated siltstone layers (Unit I2)."

Size class: macrofossils

Preservation: trace
