From Wikipedia, the free encyclopedia

The Wee Jasper reef, formerly known as the Taemas-Wee Jasper reef, was an Early Devonian (Emsian) mesophotic coral reef ecosystem located in what is now the Wee Jasper-Taemas area, New South Wales, Australia, near the border with the Australian Capital Territory. The Wee Jasper reef is considered to have been both a benthic and nektonic ecosystem, as studies of the fossilized coral reveal that said coral had adapted for low irradiance, indicating the reef developed below well-lit waters. The rocks of this reef belong to the Taemas Limestone Formation.[1]

The Burrinjuck area has immense national and international significance, as from a fossil perspective, the Wee Jasper reef preserves a diverse fauna comparable to those of World Heritage listed sites. This fauna not only includes the dominant placoderms and other fishes, but also corals, bryozoans, stromatoporoids, brachiopods, gastropods, nautiloids and trilobites.[2] However, the majority of vertebrate fossils recovered are fragmentary, in contrast to Lagerstätte deposits like the Gogo Formation in Western Australia. While the Gogo beds lack preserved corals due to anoxic bottom environments outside the reef, they frequently preserve entire animals, including soft tissues and even microscopic radiolarians in complete, three-dimensional detail.[1]
