摘要

Moderately-preserved Silurian radiolarians have been recovered from the Jenolan Caves region, eastern NSW, Australia. Radiolarians were first reported from this area in the late 19th Century by T.W. Edgeworth David, but were not described in detail, neither were they illustrated. Nearly 120 years later, the first images of these fossils are presented. The radiolarians reported include: ?Futobari cf. solidus Furutani, ?Zadrappolus sp., Haplentactiniid gen. and sp. indet, Borisella sp., ?Palaeoephippium sp., ?Insolitignum vivanima MacDonald and ?Helenifore speciosus (Furutani). The fauna is similar to others described from Upper Silurian strata in Japan.
