Wintonopus is an ichnogenus of dinosaur footprint. Its footprints have been found at Lark Quarry in Australia. The genus is named after the Winton Formation in which the tracks were found. [1] Other tracks were found in the Broome Sandstone of Dampier Peninsula, Western Australia.
Broome, also known as Rubibi by the Yawuru people, is a coastal, pearling and tourist town in the Kimberley region of Western Australia, 1,681 km (1,045 mi) north of Perth. The estimated urban population was 13,984 in August 2016. It is the largest town in the Kimberley region.
The South Polar region of the Cretaceous comprised the continent of East Gondwana–modern day Australia and Antarctica–a product of the break-up of Gondwana. The southern region, during this time, was much warmer than it is today, ranging from perhaps 4–8 °C (39–46 °F) in the latest Cretaceous Maastrichtian in what is now southeastern Australia. This prevented permanent ice sheets from developing and fostered polar forests, which were largely dominated by conifers, cycads, and ferns, and relied on a temperate climate and heavy rainfall. Major fossil-bearing geological formations that record this area are: the Santa Marta and Sobral Formations of Seymour Island off the Antarctic Peninsula; the Snow Hill Island, Lopez de Bertodano, and the Hidden Lake Formations on James Ross Island also off the Antarctic Peninsula; and the Eumeralla and Wonthaggi Formations in Australia.
The Hell Creek Formation is an intensively studied division of mostly Upper Cretaceous and some lower Paleocene rocks in North America, named for exposures studied along Hell Creek, near Jordan, Montana. The formation stretches over portions of Montana, North Dakota, South Dakota, and Wyoming. In Montana, the Hell Creek Formation overlies the Fox Hills Formation. The site of Pompeys Pillar National Monument is a small isolated section of the Hell Creek Formation. In 1966, the Hell Creek Fossil Area was designated as a National Natural Landmark by the National Park Service.
Timimus is a genus of small coelurosaurian theropod dinosaur from the Early Cretaceous of Australia. It was originally identified as an ornithomimosaur, but now it is thought to be a different kind of theropod, possibly a tyrannosauroid.
The Bayan Shireh Formation is a geological formation in Mongolia, that dates to the Late Cretaceous period. It was first described and established by Vasiliev et al. 1959.
Stegosauria is a group of herbivorous ornithischian dinosaurs that lived during the Jurassic and early Cretaceous periods. Stegosaurian fossils have been found mostly in the Northern Hemisphere, predominantly in what is now North America, Europe, Africa, South America and Asia. Their geographical origins are unclear; the earliest unequivocal stegosaurian, Huayangosaurus taibaii, lived in China.
A fossil track or ichnite is a fossilized footprint. This is a type of trace fossil. A fossil trackway is a sequence of fossil tracks left by a single organism. Over the years, many ichnites have been found, around the world, giving important clues about the behaviour of the animals that made them. For instance, multiple ichnites of a single species, close together, suggest 'herd' or 'pack' behaviour of that species.
Dinosaur Stampede National Monument at Lark Quarry Conservation Park in Australia is considered to be the site of the world's only known record of a dinosaur stampede, with fossilised footprints are interpreted as a predator stalking and causing a stampede of around 150 two-legged dinosaurs. This interpretation has been challenged in recent years, with evidence suggesting it may have been a natural river crossing. The fossils date to either the Albian or Turonian periods between 104 to 92 million years ago, and are part of the Winton Formation sandstone. In 2015 Winton Shire Council invited the Australian Age of Dinosaurs Museum of Natural History to take over the operation of public guided tours at Dinosaur Stampede National Monument. This joint initiative, implemented in April 2016, provides visitors with a broader understanding of unique Australian dinosaurs and the world they inhabited. In 2018 Dinosaur Stampede National Monument received 14,180 visitors.
The Laramie Formation is a geologic formation of Late Cretaceous (Maastrichtian) age, named by Clarence King in 1876 for exposures in northeastern Colorado, in the United States. It was deposited on a coastal plain and in coastal swamps that flanked the Western Interior Seaway. It contains coal, clay and uranium deposits, as well as plant and animal fossils, including dinosaur remains.
The Cloverly Formation is a geological formation of Early Cretaceous age that is present in parts of Montana, Wyoming, Colorado and Utah in the western United States. It was named for a post office on the eastern side of the Bighorn Basin in Wyoming by N.H. Darton in 1904. The sedimentary rocks of formation were deposited in floodplain environments and contain vertebrate fossils, including a diverse assemblage of dinosaur remains. In 1973, the Cloverly Formation Site was designated as a National Natural Landmark by the National Park Service.
Mary Julia Wade was an Australian palaeontologist, known for her role as the Deputy Director of the Queensland Museum. Some of her most renowned work was on the Precambrian Ediacaran Biota in South Australia.
The Winton Formation is a Cretaceous geological formation in central-western Queensland, Australia. It is late Albian to early Turonian in age. The formation blankets large areas of central-western Queensland. It consists of sedimentary rocks such as sandstone, siltstone and claystone. The sediments that make up these rocks represent the remnants of the river plains that filled the basin left by the Eromanga Sea - an inland sea that covered large parts of Queensland and central Australia at least four times during the Early Cretaceous. Great meandering rivers, forest pools and swamps, creeks, lakes and coastal estuaries all left behind different types of sediment.
The Griman Creek Formation is a geological formation in northern New South Wales and southern Queensland, Australia whose strata date back to the Albian-Cenomanian of the Early-Late Cretaceous. It is most notable being a major source of opal, found near the town of Lightning Ridge, New South Wales. Alongside the opal opalised fossils are also found, including those of dinosaurs and primitive monotremes.
The Wapiti Formation is a geological formation of the Western Canada Sedimentary Basin in northwestern Alberta, and northeastern British Columbia, Canada. Its deposition spanned the time interval from the lower Campanian through to the upper Maastrichtian, between approximately 80 and 68 Ma. It was named by G.M. Dawson in 1881, presumably for exposures along the lower part of the Wapiti River and downstream along the Smoky River in Alberta.
Amblydactylus is an ichnogenus that has been attributed to dinosaurs. The generic name, derived from the Greek words amblys and dáktylos, means "dull finger". Two species of Amlydactylus have been named: A. gethingi, which references the Gething Formation where it was found; and A. kortmeyeri, which honours Carl Kortmeyer who discovered the holotype.
Australovenator is a genus of megaraptoran theropod dinosaur from Cenomanian -age Winton Formation of Australia. It is known from partial cranial and postcranial remains which were described in 2009 by Scott Hocknull and colleagues, although additional descriptions and analyses continue to be published. It is the most complete predatory dinosaur discovered in Australia.
Wintonotitan is a genus of titanosauriform dinosaur from late Albian -age Winton Formation of Australia. It is known from partial postcranial remains.
The Broome Sandstone is an Early Cretaceous geologic formation found in Western Australia, and formerly considered part of Dampier Group. Fossil sauropod tracks, belonging to an unknown ichnotaxon, and stegosaur tracks belonging to the ichnogenus and species Garbina roeorum have been reported from the formation.
Tyrannosauropus is a dubious ichnogenus of tridactyl dinosaur footprint from the Campanian of the Late Cretaceous of North America. Tyrannosauropus was named for a collection of footprints discovered on the ceiling of a cave in Utah which were suggested to have been made by Tyrannosaurus and informally labelled as "Tyrannosauripus" in 1924. These footprints would later be named by Haubold in 1971 as Tyrannosauropus petersoni, and attributed to Tyrannosaurus rex. However, Tyrannosauropus are Campanian in age, pre-dating the Maastrichtian age for Tyrannosaurus, and the morphology of the footprints more closely resembles those of hadrosaurid dinosaurs than those of theropods. Furthermore, in 1994 another footprint was described as likely belonging to Tyrannosaurus that matched it in both age and morphology and was named Tyrannosauripus. In the same publication, the description of Tyrannosauropus was deemed inadequate, with the holotype damaged and lost, and the ichnotaxon was declared undiagnostic and thus a nomen dubium.
Savannasaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Winton Formation of Queensland, Australia. It contains one species, Savannasaurus elliottorum, named in 2016 by Stephen Poropat and colleagues. The holotype and only known specimen, originally nicknamed "Wade", is the most complete specimen of an Australian sauropod, and is held at the Australian Age of Dinosaurs museum. Dinosaurs known from contemporary rocks include its close relative Diamantinasaurus and the theropod Australovenator; associated teeth suggest that Australovenator may have fed on the holotype specimen.
