Talbragar Fish Beds
The Talbragar Fish Beds were a small lake near Gulgong in NSW. A heavy ash fall from the Garrawilla volcano, in the late Jurassic, buried this lake quickly and so preserved many fish and plant specimens from this period.
The most common small fish were known as Leptolepsis talbragarensis but are now classified as Cavenderichthys talbragarensis. Eight different fossil fish have been identified from these deposits.
The most common plant fossil is agathis jurassica, believed to be the ancestor of the Wollemi Pine.
The vegetation around the lake at that time was dominated by agathis jurassica with some Podocarp Conifers and an understory of Cycadophytes, Seed Ferns and Ferns, in a heath environment.
The main fossil deposit is now protected from further collecting.
