Silurian linguliformean brachiopods and conodonts are documented and described from the type section through the Cobra Formation (Taralga Group) in Murruin Creek, near Taralga. The linguliformean brachiopod fauna includes linguloids (six taxa), discinoids (three taxa), acrotretoids (four taxa) and a siphonotretoid. These are the first Late Silurian linguliformean brachiopods to be documented from eastern Australia. New taxa include Acrotretella dizeugosa sp. nov., upon which is based the first detailed description of the ontogeny of Acrotretella Ireland, 1961. Eleven multi-element conodont taxa are recognised, including the temporally significant taxon, Kockelella maenniki Serpagli and Corradini, 1998. Based on these conodont data, and other faunal elements, the Cobra Formation in Murruin Creek appears to range from mid-Wenlock? to mid-Ludlow (early to mid-siluricus Zone) in age.
