Queensland: Australotitan cooperensis, the largest dinosaur found in Australia
Queensland is home to some of the world's best-preserved fossils, including those of Australotitan cooperensis, the largest dinosaur found in Australia. This dinosaur was an extinct genus of possibly titanosaurian somphospondylan dinosaurs from the Late Cretaceous Winton Formation of southern-central Queensland. The specific name, "cooperensis", refers to the Cooper Creek system near the initial location of the holotype and the nickname given to it when it was first discovered.
The generic name, "Australotitan", combines the Latin word "australis", meaning "southern" as it was found in Australia, with the Greek word "Tιτάν", meaning "titan", in reference to the Greek mythological Titans and the dinosaur's gigantic size. Australotitan was discovered in 2005 in layers of the Winton Formation in southwest Queensland, near the town of Eromanga. Parts of its skeleton was found by Sandy Mackenzie at Plevna Downs, and the fossil material was then prepared and excavated in conjunction with the Queensland Museum and the Eromanga Natural History Museum between November 2005 and April 2010.
The Australotitan cooperensis is estimated to have lived in the mid-Cretaceous period, with an estimated maximum depositional age of between 93-96 million years ago. It is considered a new giant sauropod, reaching a size similar to that of the giant titanosaurians from South America based on limb-size comparisons. This discovery represents the first record of dinosaurs from the southern-central Winton Formation of the Eromanga Basin, Australia.
The holotype of Australotitan was found to be closely related to Diamantinasaurus, a contemporary relative. In fact, Beeston et al. (2024) proposed that Australotitan may not have sufficient distinct features to distinguish it from Diamantinasaurus, suggesting that it could be considered an indeterminate member of the clade Diamantinasauria. This proposal highlights the ongoing revisions and advancements in our understanding of Australia's dinosaur history.

Lightning Ridge, NSW: Weewarrasaurus and Fostoria, two new dinosaur species
Dinosaur fossils have been found across Australia, with some of the world's best-preserved fossils discovered in Outback Queensland. The towns of Hughenden, Richmond, and Winton are home to these fossils, which include evidence of a dinosaur stampede, ancient marine reptile fossils, and the largest Australian fossil collection.
Lightning Ridge in New South Wales (NSW) is one notable site where two new dinosaur species have been discovered: Weewarrasaurus and Fostoria. The former was identified following the chance discovery of a jawbone fragment in a bucket of opal rubble from the Wee Warra opal field near Lightning Ridge. Weewarrasaurus pobeni, named in honour of Mike Poben, who donated the specimen for research, is the first new dinosaur to be named in NSW in almost a century. It is believed to have been a small, plant-eating, ornithopod dinosaur that lived during the Cretaceous Period about 100 million years ago when the region was covered by ancient floodplains.
Fostoria dhimbangunmal, on the other hand, was an Iguanodon-like dinosaur, similar to the famous Muttaburrasaurus from central Queensland. It lived during the mid-Cretaceous period, about 100 million years ago, when the area was a broad floodplain with lakes and rivers flowing into the inland Eromanga Sea. Fostoria was a large dinosaur, about the length of an elephant, and walked primarily on its hind limbs, although it may have occasionally used all four for movement. The species name "dhimbangunmal" means "sheep yard" in the local Yuwaalaraay and Yuwaalayaay Aboriginal languages, recognising the Sheepyard opal field near Lightning Ridge where its fossils were discovered by opal miner Robert Foster in the 1980s.
The discoveries of Weewarrasaurus and Fostoria at Lightning Ridge, NSW, are significant contributions to the understanding of Australia's prehistoric past and the dinosaur species that inhabited the region during the Cretaceous Period.

Western Australia: Ozraptor, a partial theropod shinbone
Dinosaur bones have been found in various locations across Australia, with some of the most notable discoveries made in Queensland and Western Australia. One of the significant finds in Western Australia is the Ozraptor, a partial theropod shinbone discovered in 1966.
The Ozraptor, or "Australian thief" in Greek, is a genus of abelisauroid theropod dinosaurs from the Middle Jurassic era in Australia. The discovery of the Ozraptor is credited to a group of four Year 12 Scotch College geology students who, in 1966, found a fossil during a field exercise at the Bringo Railway Cutting site near Geraldton. The students showed their find to Professor Rex Prider of the University of Western Australia, who had a cast made and sent it to experts at the British Museum of Natural History in London. Initially, the experts believed the fossil likely belonged to an extinct turtle.
It wasn't until the 1990s that the true nature of the fossil was revealed. John Albert Long and Ralph Molnar re-evaluated the bone after it had been prepared out of the rock, and they classified it as the shinbone of a theropod. The partial leg bone, measuring 8 centimetres long and 4 centimetres wide at the lower end, provided crucial insights into the distinct species. Based on these measurements, the entire shinbone was estimated to be about 17 to 20 centimetres long, indicating that the animal as a whole was approximately 2 metres long.
The Ozraptor was officially named and described as Ozraptor subotaii in 1998 by Long and Molnar. The generic name combines "Ozzies," a nickname for Australians, with the Latin "raptor," meaning "seizer." Despite the initial discovery in 1966, it took several decades and further studies for scientists to fully recognise the significance of the find and classify the Ozraptor as a distinct species of dinosaur.

Victoria: Atlascopcosaurus, a small, 2-legged ornithopod dinosaur
Dinosaur fossils have been found in various locations across Australia, including Queensland, New South Wales, and Victoria.
The Atlascopcosaurus loadsi was a small, herbivorous ornithopod dinosaur discovered on the coast of Victoria in 1984. The name Atlascopcosaurus was given to the species in honour of the company Atlas Copco, which provided assistance and equipment during the excavation process.
The discovery of Atlascopcosaurus was based on a fragment of the upper jaw with teeth, as well as several other jawbones. Unfortunately, no other bones have been associated with these jaws, making it challenging to assign non-jaw specimens to this species. Atlascopcosaurus is estimated to have been around 2-4 meters in length and weighed about 125 kilograms. It had an unusual five-fingered hand, with the three middle fingers ending in hoof-like claws.
The excavations at Dinosaur Cove, an area on the southeast coast of Australia near Victoria, yielded important findings. Dr Thomas H Rich from the Museum of Victoria and Patricia Vickers-Rich from Monash University led research projects in this area for over a decade. During his first visit in 1980, Dr Rich and his colleagues discovered fragments of rock-embedded bone. Four years later, a large group of volunteers, paleontology scientists, and miners began excavations, with Atlas Copco among those contributing equipment and assistance.
The fossils discovered at Dinosaur Cove were embedded in layers of sand, mud, and clay, which, over millions of years, had been pressed together into hard rock. The fossils found at this site have provided valuable insights into the early Cretaceous Period, approximately 100-120 million years ago.

Richmond and Winton: Home to some of the world's best-preserved fossils
Australia has produced some spectacular dinosaur fossils in recent years, with new species being discovered and described. The Australian Age of Dinosaurs Museum of Natural History in Winton, Queensland, is home to the world's largest collection of Australian dinosaur fossils. Winton is a small outback town, and the museum is located on a sheep station 24km southwest of the town. The museum includes a Fossil Preparation Laboratory, a Reception Centre, and the March of the Titanosaurs exhibition at Dinosaur Canyon.
The museum was established as a non-profit organisation in 2002 by David and Judy Elliott and was originally based at Belmont. In 2006, the Britton family donated a rugged mesa known as "The Jump-Up", located 24km south-west of Winton, and the museum relocated there in 2009.
The Australian Age of Dinosaurs Museum is not the only place in Australia with dinosaur fossils. In Lightning Ridge, New South Wales, dinosaur bones have been found in opal deposits, with the bones being replaced by opal over time. Two new species, the ornithopods Weewarrasaurus and Fostoria, have been described from these deposits.
In addition to bones, trackways (preserved footprints) have been discovered in Queensland, providing evidence of theropods from the Late Triassic to Middle Jurassic periods. These trackways are significant in filling in the gaps in the fossil record when body fossils are scarce.
Outside of Australia, in the state of Virginia in the United States, dinosaur fossils have also been discovered. Virginia is considered relatively rich in dinosaur fossils, with 280 records, placing it in the top 10 states with known fossils. Fossilized tracks of species such as Grallator and Eubrontes have been found in the Richmond, Danville, and Culpeper basins, providing evidence of dinosaurs walking in the area around 220 million years ago.
