The Mesozoic strata of Katherine and Fergusson River 1:250 000 sheets

Updated: 2026-05-04

Lower Cretaceous strata of the Katherine and the Fergusson River 1:250,000 Sheets were examined during the 1960 and 1961 field seasons. Field observations on lithology and palaeogeography were summarised in previous Records (Skwarko,1961a,b) and these, together with the identification of the fossils collected and their dating have provided material for conclusions expressed in the present Record. Of the thirteen assemblages of fossils collected on the Katherine-Ferguson River area, nine are marine and four consist of plant remains. They appear to range in age from Neocomian to uppermost Albian. Lower Cretaceous sediments.
