Silurian brachiopod distribution in strata of the Canberra-Yass region, southeastern Australia

Abstract

Brachiopod faunas from Silurian strata in the Yass and Canberra districts of southeastern New South Wales and the Australian Capital Territory have been revised or described by the author in a number of papers between 1982 and 2010. In this paper, the stratigraphic distribution of the species of Rhynchonellata is displayed in a series of charts arranged by Order and level of first appearance. Stratigraphic correlation between the two neighbouring areas is based on detailed mapping by geologists of the former Bureau of Mineral Resources (now Geoscience Australia); biostratigraphy relies on incomplete sequences of conodont and graptolite zones in the Yass succession.
