In New South Wales, at Tallong, the Upper Ordovician Graptolites are well represented by such forms as Dicellograptus elegans, Dicranograptus nicholsoni, Diplograptus carnei, D. foliaceus, Cryptograptus tricornis and Glossograptus quadrimucronatus, etc. Other localities in New South Wales for this Graptolite fauna are Stockyard Creek, Currowang, Tingaringi, Lawson, and Mandurama.
Tasmania.—
From Tasmania a Diplograptus has been recorded, but the particular horizon and locality are uncertain.
Silurian Graptolites, Victoria.—
In the Silurian shales at Keilor, in Victoria, Monograptus is a common genus, and Cyrtograptus and Retiolites australis ([Fig. 75 F]) also occur. Several species of Monograptus have also been found at South Yarra and Studley Park. At the latter place and Walhalla Monograptus dubius, which is a Wenlock and Ludlow fossil in Britain, has been found in some abundance ([Fig. 75 G]).
