• inversum Zone

Collected by C.J. Underwood, D. Ward

Collection methods: bulk, mechanical, sieve,

• focus on fish remains; Bulk samples of clay, 30–70 kg in dry weight, were sieved for fish material using a 125 mm or 250 mm mesh. The residues were picked for fish remains at size fractions down to 355 mm where possible, but coarse glauconite in some samples meant that picking size fractions below 500 mm was impractical. All specimens cited here are deposited in Liverpool Museum, National Museums and Galleries on Merseyside (LIVCM).
