At the {{CensusAU|2011}}, Koonwarra had a population of 385.[1] The town straddles the South Gippsland Highway.[2] 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.[3] Koonwarra fossil bedThe 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.[4] Among them is the unusual finding of a fossil horseshoe crab described as Victalimulus mcqueeni.[5] 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.[6] A fossil member of the Ginkgo family, Ginkgoites australis, has also been recovered.[7] 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.[8] References1. ^1 {{Census 2011 AUS | id = SSC20732| name = Koonwarra (State Suburb) | accessdate = 1 December 2014 | quick = on}} {{Towns in South Gippsland Shire}}2. ^{{cite book|last=Wheeler|first=Donna |title=Discover Melbourne & Victoria|publisher=Lonely Planet|date=2008|pages=278|isbn=9781741048629|url=https://books.google.com/books?id=6cPhKmejxVEC&pg=PA278&dq=koonwarra&hl=en&sa=X&ei=b5FvVPzTCYK_sQS3tYKQBQ&ved=0CCMQ6AEwAQ#v=onepage&q=koonwarra&f=false}} 3. ^{{cite web|url=http://www.visitpromcountry.com.au/towns/koonwarra|title=Koonwarra|last= Prom Country Regional Tourism Inc. |date=2012|work=Visit Prom Country|publisher=South Gippsland Shire Council |accessdate=22 November 2014}} 4. ^{{cite web|url=http://museumvictoria.com.au/treasures/colldetails.aspx?pid=56|title=Koonwarra fossil bed|date=2004|work=Treasures: Museum Victoria Celebrates 150 Years|publisher=Museum Victoria|accessdate=22 November 2014}} 5. ^{{cite journal|author1=Riek, E.F. |author2=Gill, E.D. |year= 1971 |title= A new xiphosuran genus from Lower Cretaceous freshwater sediments at Koonwarra, Victoria, Australia |journal=Palaeontology |volume=14 |issue=2|pages= 206–10 |url=http://www.palass-pubs.org/palaeontology/pdf/Vol14/Pages%20206-210.pdf}} 6. ^{{cite journal|author1=V.A.
