Balangi (Esch collection) (Cretaceous of Cameroon)

Where: Cameroon (4.5° N, 9.5° E: paleocoordinates 9.5° S, 1.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Mungo River Formation, Coniacian (89.8 - 86.3 Ma)

• The Esch expedition collected material largely from float blocks, so many localities contain a mixed ammonite fauna. Some specimens also appear to be mislabeled or the locality is questioned by Reyment (1954, 1958).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithology not reported

Size class: macrofossils

Collected by E. Esch in 1897-1898; reposited in the MfN
