Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among ...

Atlascopcosaurus Loadsi
''Atlascopcosaurus'' () is a genus of herbivorous basal iguanodont dinosaur from the Early Cretaceous of the present Australia. Classification The type specimen, NMV P166409, was found in 1984 at the Dinosaur Cove East site at the coast of Victoria, in layers of the Eumeralla Formation dating from the early Cretaceous, Aptian-Albian. The holotype consists of a piece of the upper jaw, a partial maxilla with teeth, and referred specimens include teeth, another maxilla, and dentaries. Although the rest of the skeleton is unknown it can be inferred from closely related species that the genus represents a small bipedal herbivore. By extrapolation it has been estimated that it was about two to three metres (6.5–10 ft) long and weighed approximately 125 kg. The type species, ''Atlascopcosaurus loadsi'', was named and described by Tom Rich and Patricia Vickers-Rich in 1989. The generic name refers to the Atlas Copco Company who had provided equipment for the dig that disc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Jurassic
The Early Jurassic Epoch (geology), Epoch (in chronostratigraphy corresponding to the Lower Jurassic series (stratigraphy), Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic-Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.1 Ma. Certain rocks of marine origin of this age in Europe are called "Lias Group, Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an England, English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornwall, Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias limestone from S ...

Hanson Formation
The Hanson Formation (also known as the Shafer Peak Formation) is a geologic formation on Mount Kirkpatrick and north Victoria Land, Antarctica. It is one of the two major dinosaur-bearing rock groups found on Antarctica to date; the other is the Snow Hill Island Formation and related formations from the Late Cretaceous of the Antarctic Peninsula. The formation has yielded some Mesozoic specimens, but most of it is as yet unexcavated. Part of the Victoria Group of the Transantarctic Mountains, it lies below the Prebble Formation and above the Falla Formation. The formation includes material from volcanic activity linked to the Karoo-Ferar eruptions of the Lower Jurassic. The climate of the zone was similar to that of modern southern Chile, humid, with a temperature interval of 17–18 degrees. The Hanson Formation is correlated with the Section Peak Formation of the Eisenhower Range and Deep Freeze Range, as well as volcanic deposits on the Convoy Range and Ricker Hills of south ...

Cryolophosaurus
''Cryolophosaurus'' ( or ; "CRY-oh-loaf-oh-SAWR-us") is a genus of large theropod dinosaur known from only a single species ''Cryolophosaurus ellioti'', from the early Jurassic of Antarctica. It was one of the largest theropods of the Early Jurassic, with the subadult being estimated to have reached long and weighed . ''Cryolophosaurus'' was first excavated from Antarctica's Early Jurassic, Pliensbachian aged Hanson Formation, formerly the upper Falla Formation, by paleontologist Dr. William Hammer in 1991. It was the first carnivorous dinosaur to be discovered in Antarctica and the first non-avian dinosaur from the continent to be officially named. The sediments in which its fossils were found have been dated at ~194 to 188 million years ago, representing the Early Jurassic Period. ''Cryolophosaurus'' is known from a skull, a femur and other material, all of which have caused its classification to vary greatly. The femur possesses many primitive characteristics that have cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austrosaurus LM
''Austrosaurus'' (; ) was an extinct genus of titanosaurian sauropod dinosaur from the Allaru Formation, from the early Cretaceous (112-105 million years ago) of Central-Western Queensland in Australia. Discovery and species The holotype, QM F2361 (consisting of three blocks containing primitive and badly weathered vertebrae and rib fragments, with a further 5 large blocks and at least 10 smaller ones later assigned to the holotype as well), was discovered by Mr. H.B. Wade on Clutha Station near Maxwelton in north Queensland in 1932, who alerted the station manager H. Mackillop, who showed his brother who sent them to the Queensland Museum. ''Austrosaurus'' was described by Heber Longman in 1933. Paleobiology Originally it was thought that sauropods spent time near or in water to relieve weight from their legs. However, this theory is now rejected and it is believed that ''Austrosaurus'' like all sauropods lived on dry land. Fossil finds suggest a height of approximately 3. ...

Australovenator Reconstruction
''Australovenator'' (meaning "southern hunter") is a genus of megaraptoran theropod dinosaur from Cenomanian (Late Cretaceous)-age Winton Formation (dated to 95 million years ago) 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. It has been suggested that ''Australovenator'' is a sister taxon to ''Fukuiraptor'', although some phylogenetic analyses find it to be a more derived member of the Megaraptora, possibly being part of the main Megaraptoridae family itself. History of discovery ''Australovenator'' is based on a theropod specimen ( AODF 604), affectionately nicknamed "Banjo" after Banjo Paterson, which was found intermingled with the remains of the sauropod ''Diamantinasaurus matildae'' at the "Matilda site" ( AODL 85). The parts of the holot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australotitan Cooperensis
''Australotitan'' () is an extinct genus of titanosaurian sauropod that existed during the Cenomanian-Turonian age of the Late Cretaceous in what is now southern-central Queensland, Australia. The genus contains a single species, ''Australotitan cooperensis''. Discovery and naming ''Australotitan'' was discovered in 2005 within the Winton Formation of southwest Queensland, Australia, near the town of Eromanga. Sandy Mackenzie, the discoverer, had already collected other bones on the land of his parents in 2004. 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. It was nicknamed "Cooper" after its discovery being from the Cooper-Eromanga Basin, Cooper Creek system, ‘the Cooper Country”. The holotype, EMF102 (nicknamed "Cooper"), was described in 2021 on the basis of a partial skeleton consisting of a partial left scapula, partial left and complete right hum ...

Turonian
The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.8 Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage. At the beginning of the Turonian an oceanic anoxic event (OAE 2) took place, also referred to as the Cenomanian-Turonian boundary event or the "Bonarelli Event". Stratigraphic definition The Turonian (French: ''Turonien'') was defined by the French paleontologist Alcide d'Orbigny (1802–1857) in 1842. Orbigny named it after the French city of Tours in the region of Touraine (department Indre-et-Loire), which is the original type locality. The base of the Turonian Stage is defined as the place where the ammonite species '' Watinoceras devonense'' first appears in the stratigraphic column. The official reference profile (the GSSP) for the base of the Turonian is located in the Roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
