Fauna 5, 28.3 km from Calabar, south-east Nigeria (Cretaceous of Nigeria)

Where: Nigeria (5.2° N, 8.3° E: paleocoordinates 10.1° S, 0.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Odukpani Formation, Middle Cenomanian (99.6 - 93.5 Ma)

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, gray shale

• 'The Odukpani Formation and Nkporo Shale are well exposed in road cuttings north-west of Calabar... The exposed parts of the Odukpani Formation consist here mainly of grey shales, pyritic at the base but calcareous and including numerous thin limestones higher up. A well-developed limestone-shale sequence occurs close to the top of the formation and at its base are the remnants after dissolution of another prominent limestone horizon.'

Size class: macrofossils

Preservation: mold/impression

Collection methods: specimens in the Department of Palaeontology, British Museum (Natural History), London, and in the Department of Geology, University of Ilorin, Nigeria; probably own field collection
