Talbragar fossil site

The Talbragar fossil site is a paleontological site of Jurassic age in the central west of New South Wales, Australia. It lies about 30 kilometres (19 mi) north-east of the town of Gulgong, and 300 kilometres (190 mi) north-west of Sydney. The site has been known for over a century during which it has been extensively excavated to the point of near exhaustion. It is now registered as a Crown Land Reserve for the preservation of fossils; access is by permit, and the collection of rocks and fossil specimens is prohibited.[2] The 4-hectare (9.9-acre) reserve is listed on the (now defunct) Register of the National Estate.

Fossils

The fossil-bearing rocks are fine-grained siltstones and mudstones that are part of the Purlawaugh formation. They occur mainly as loose blocks and weathered shales over an area of about 300 by 80 metres (980 by 260 ft), with a thickness of no more than 60 centimetres (24 in). They are thought to be the remnants of sediments from a small freshwater lake, surrounded by forest, which existed about 175 million years ago when Australia was part of Gondwana. The site is the only Jurassic fish site known in New South Wales.[2]

The fossil material consists principally of the fishes that lived in the lake, as well as plants from the forest, whose remains accumulated in the sediments on the lake bed and were preserved. Among the many species discovered are sixteen kinds of plant, eight kinds of fish, several insects and a spider.[2]

gollark: Yes, and if you have Code Page 437 or whatever stuff then each character represents a byte, so it's fine.
gollark: It's the same amount of data either way.
gollark: Why?
gollark: It's not cheaty. It's representing the bytes in a nicer format.
gollark: (because CPUs are basically pandering to ancient models of computing nobody can shift and GPUs are good-ish but only for very parallel tasks)
