Koonwarra fossil bed
The Koonwarra fossil bed was found by accident in 1961 during roadworks to realign a segment of the South Gippsland Highway. Dating from the early Cretaceous 115 million years ago, they are composed of mudstone sediment thought to have been laid down in a freshwater (possibly cool-climate subalpine) lake.The site is an important element of Australia's fossil record, with plants, insects (including mayflies, dragonflies, cockroaches, beetles, fleas, flies and wasps), spiders, crustaceans and fish recovered. Among them is the unusual finding of a fossil horseshoe crab described as Victalimulus mcqueeni. Small segments of a leafy twig have been recovered that were thought to be one of the oldest angiosperms (flowering plants) discovered; more recent examination reports anatomy more typical of a gnetophyte, a group of organisms for which there is a scant fossil record. A fossil member of the Ginkgo family, Ginkgoites australis, has also been recovered.
Six well-preserved feathers have been recovered, indicating more complete remains of feathered dinosaurs might be found, however the site has been little-excavated, extensive removal of overlying rock has to take place before further excavation.
