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 been ...

Division Of Monash
The Division of Monash is an Australian Electoral Division in the state of Victoria, which was contested for the first time at the 2019 federal election. Geography Federal electoral division boundaries in Australia are determined at redistributions by a redistribution committee appointed by the Australian Electoral Commission. Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned. History The division is named in honour of Sir John Monash, an Australian Allied military commander during World War I. The Division of Monash is located in the western part of the Gippsland region, which extends for the length of Victoria's eastern Bass Strait coastline. It replaced the similarly-located Division of McMillan in 2018. Monash includes the towns of Warragul, Moe, Wonthaggi, Leongatha and Foster. The seat gained Phillip ...

South Gippsland
South Gippsland, a region of Gippsland in Victoria, Australia, is a well-watered region consisting of low, rolling hills descending to the coast in the south and the Latrobe Valley in the north. Low granite hills continue into Wilsons Promontory, the southernmost point of Victoria and mainland Australia. Rivers are generally very short and impossible to dam owing to the lack of potential storage sites, but groundwater of good quality is readily available. The major industries are forestry and dairy farming, and the principal towns include Cowes (on Phillip Island), Leongatha, Korumburra, Wonthaggi and Foster. Wilsons Promontory National Park features eucalypt forests and rainforests as well as its famous beaches, and is one of the most popular holiday areas in Victoria. Linked to mainland South Gippsland via a bridge at San Remo, Phillip Island is also a major tourist destination, noted particularly for its surf beaches, nightly Penguin Parade and Grand Prix track. 12,000 y ...

South Gippsland Highway
The South Gippsland Highway is a partially divided highway in Victoria, Australia which connects the city of Melbourne with the South Gippsland region of Victoria, ending in the town of Sale. The highway begins at Lonsdale Street (Princes Highway), Dandenong. At the Greens Road intersection, it adopts Metropolitan Route 12 until Pound Road, then continues until the South Gippsland Freeway / Western Port Highway interchange where it becomes the M420. The M420 continues through and until the Bass Highway turnoff, at which point the road is then designated A440 onwards to Sale. From the Bass Highway junction, the highway is undivided. The South Gippsland Highway is the gateway from Melbourne to many attractions including Wilsons Promontory and Phillip Island as well as being an important road for farmers in Gippsland. Route The highway commences in Dandenong, branching from the Princes Highway, and heads in a general south-east direction at first. It is mostly a dual carriagewa ...

Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horseshoe Crab
Horseshoe crabs are marine and brackish water arthropods of the family Limulidae and the only living members of the order Xiphosura. Despite their name, they are not true crabs or crustaceans: they are chelicerates, most closely related to arachnids, such as spiders and scorpions. Horseshoe crabs live primarily in and around shallow coastal waters on soft, sandy or muddy bottoms. They are generally found in the intertidal zone at spring high tides. They are eaten in some parts of Asia, and used as fishing bait, in fertilizer and in science (especially ''Limulus'' amebocyte lysate). In recent years, population declines have occurred as a consequence of coastal habitat destruction and overharvesting. Tetrodotoxin may be present in one horseshoe crab species, '' Carcinoscorpius rotundicauda''. Fossil records for horseshoe crabs extend back as far as 480 million years ago, with extant forms being living fossils. A 2019 molecular analysis places them as the sister group of Ricinule ...

Gnetophyte
Gnetophyta () is a division of plants (alternatively considered the subclass Gnetidae or order Gnetales), grouped within the gymnosperms (which also includes conifers, cycads, and ginkgos), that consists of some 70 species across the three relict genera: ''Gnetum'' (family Gnetaceae), ''Welwitschia'' (family Welwitschiaceae), and ''Ephedra'' (family Ephedraceae). Fossilized pollen attributed to a close relative of ''Ephedra'' has been dated as far back as the Early Cretaceous. Though diverse in the Early Cretaceous, only three families, each containing a single genus, are still alive today. The primary difference between gnetophytes and other gymnosperms is the presence of vessel elements, a system of conduits that transport water within the plant, similar to those found in flowering plants. Because of this, gnetophytes were once thought to be the closest gymnosperm relatives to flowering plants, but more recent molecular studies have brought this hypothesis into question. Thoug ...

Ginkgo
''Ginkgo'' is a genus of non-flowering seed plants. The scientific name is also used as the English name. The order to which it belongs, Ginkgoales, first appeared in the Permian, 270 million years ago, and is now the only living genus within the order. The rate of evolution within the genus has been slow, and almost all its species had become extinct by the end of the Pliocene. The sole surviving species, ''Ginkgo biloba'' is only found in the wild in China, but is cultivated around the world. The relationships between ginkgos and other groups of plants are not fully resolved. Prehistory The ginkgo (''Ginkgo biloba'') is a living fossil, with fossils similar to the modern plant dating back to the Permian, 270 million years ago. The closest living relatives of the clade are the cycads, which share with the extant ''G. biloba'' the characteristic of motile sperm. The ginkgo and cycad lineages are thought to have an extremely ancient divergence dating to the early Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
