Anaspidesidae
Anaspidesidae is a family of freshwater crustacean that is endemic to Tasmania, Australia. The family contains 3 living genera. This group of crustaceans are considered living fossils. They are commonly and collectively known as the Tasmanian anaspid crustaceans. This family is originally called as Anaspididae. However, genus name ''Anaspis'' was preoccupied by the insect genus, ''Anaspis'' Geoffroy, 1762, and therefore, in 2017, the family was renamed to Anaspidesidae by Shane Ahyong and Miguel A. Alonso-Zarazaga. Anaspiesids have stalked eyes, long antennae and antennules, and a slender body with no carapace. The two species of ''Allanaspides'' and the single species of ''Paranaspides'' are all listed as vulnerable on the IUCN Red List. Taxonomy After Höpel ''et al.''

Anaspides Eberhardi
''Anaspides'' is a genus of freshwater crustaceans in the family Anaspidesidae. The genus was first described in 1894 by George Malcolm Thomson.

Koonwarra, Victoria
Koonwarra is a town in the South Gippsland region of Victoria, Australia. At the , Koonwarra had a population of 404. The town straddles the South Gippsland Highway. Located around 128 km southeast of Melbourne, the town was served by rail from the 1890s until 1991 with the closing of the rail line to Barry Beach. 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, it is 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 b ...
