Abstract

Late Llandovery (Early Silurian) graptolites from several localities in the Merriangaah Siltstone, Quidong Basin, southern NSW, are described as Monograptus priodon (Bronn, 1835), Oktavites falx (Suess, 1851) and Oktavites bodentoeriensis Loydell, 2003. This is the first use of the generic name Oktavites in Australia. The firm age for this fauna to the spiralis graptolite Biozone and new age data from the Quidong Limestone place a maximum age for the unconformity between the Siltstone and the overlying Quidong Limestone, constraining the Quidongan Orogeny between the latest part of the Llandovery and the late or latest Wenlock.
