Ozraptor
''Ozraptor'' (meaning "Australian thief") is a genus of possibly abelisauroid theropod dinosaur from the Middle Jurassic (Bajocian) Colalura Sandstone of Australia, known from fragmentary remains. Discovery and naming In 1967 a group of four twelve-year-old Scotch College schoolboys found a fossil at the Bringo Railway Cutting site near Geraldton, which they showed to professor Rex Prider of the University of Western Australia. He had a cast made that he sent to experts of the British Museum of Natural History in London who thought it likely belonged to an extinct turtle. Re-evaluation of the bone in the 1990s after being prepared out of the rock by John Albert Long and Ralph Molnar classified the fossil as the shinbone of a genus of theropods.Long, J.A. (1998). ''Dinosaurs of Australia and New Zealand and other animals of the Mesozoic Era''. Harvard University Press, UNSW Press, pp 94-96. In 1998 Long and Molnar named and described the type (and only) species ''Ozraptor s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abelisauroidea
Abelisauroidea is typically regarded as a Cretaceous group, though the earliest abelisauridae remains are known from the Middle Jurassic of Argentina (classified as the species Eoabelisaurus mefi) and possibly Madagascar (fragmentary remains of an unnamed species) possible abelisauridae remains (an isolated left tibia, right femur, and right tibia) were also discovered in Late Jurassic Tendaguru Beds in Tanzania. Abelisauroids flourished in the Southern hemisphere during the Cretaceous period, but their origins can be traced back to at least the Middle Jurassic, when they had a more global distribution (the earliest known abelisauroid remains come from Australian and South American deposits dated to about 170 million years ago). By the Cretaceous period, abelisauroids had apparently become extinct in Asia and North America, possibly due to competition from tyrannosauroids. However, advanced abelisauroids of the family Abelisauridae persisted in the southern continents until the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colalura Sandstone
The Colalura Sandstone is a Middle Jurassic geologic formation of the Perth Basin of Western Australia. The formation overlies the Moonyoonooka Sandstone. Dinosaur remains have been recovered from the formation. Vertebrate paleofauna Few remains of the sandstone have been assigned to a genus. Unassigned remains include rare reptilian bones such as an isolated plesiosaur vertebra and paddle. Flora Petrified wood is very common in the Colalura Sandstone.

Avetheropoda
Avetheropoda, or "bird theropods", is a clade that includes carnosaurians and coelurosaurs to the exclusion of other dinosaurs. Definition Avetheropoda was named by Gregory S. Paul in 1988, and was first defined as a clade by Currie and Padian in 1997, to include ''Allosaurus'', modern birds, and other animals descended from their most recent ancestor. In 1999, Paul Sereno named another group, Neotetanurae, for the clade containing Allosauroidea and Coelurosauria, and excluding other tetanurans such as megalosauroids, but this definition was published slightly later. A monophyletic Avetheropoda is recovered in many papers, however recent findings suggest a monophyletic Carnosauria model with allosauroids and megalosauroids being each other’s closest relatives instead of Allosaurs and Coelurosaurs. Classification The cladogram A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladog ...

Incertae Sedis
' () or ''problematica'' is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by ' (of uncertain family), ' (of uncertain suborder), ' (of uncertain order) and similar terms. Examples *The fossil plant '' Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Bocage's longbill, ''Motacilla bocagii' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Medial Condyle Of Femur
The medial condyle is one of the two projections on the lower extremity of femur, the other being the lateral condyle. The medial condyle is larger than the lateral (outer) condyle due to more weight bearing caused by the centre of mass being medial to the knee. On the posterior surface of the condyle the linea aspera The linea aspera ( la, rough line) is a ridge of roughened surface on the posterior surface of the shaft of the femur. It is the site of attachments of muscles and the intermuscular septum. Its margins diverge above and below. The linea asper ... (a ridge with two lips: medial and lateral; running down the posterior shaft of the femur) turns into the medial and lateral supracondylar ridges, respectively. The outermost protrusion on the medial surface of the medial condyle is referred to as the "medial epicondyle" and can be palpated by running fingers medially from the patella with the knee in flexion. It is important to take into consideration the differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Talus Bone
The talus (; Latin for ankle or ankle bone), talus bone, astragalus (), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot.Platzer (2004), p 216 The talus has joints with the two bones of the lower leg, the tibia and thinner fibula. These leg bones have two prominences (the lateral and medial malleoli) that articulate with the talus. At the foot end, within the tarsus, the talus articulates with the calcaneus (heel bone) below, and with the curved navicular bone in front; together, these foot articulations form the ball-and-socket-shaped talocalcaneonavicular joint. The talus is the second largest of the tarsal bones; it is also one of the bones in the human body with the highest percentage of its surface area covered by articular cartilage. It is also unusual in that it has a retrograde blood supply, i.e. arterial blood enters the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhoetosaurus
''Rhoetosaurus'' (meaning "Rhoetos lizard"), named after Rhoetus, a titan in Greek Mythology, is a genus of sauropod dinosaur from the Jurassic ( Oxfordian) Walloon Coal Measures of what is now eastern Australia. ''Rhoetosaurus'' is estimated to have been about long, weighing about .Paul, G.S., 2010, ''The Princeton Field Guide to Dinosaurs'', Princeton University Press p. 173 Subsequent authors have sometimes misspelled the name: ''Rhaetosaurus'' (de Lapparent & Laverat, 1955); ''Rheteosaurus'' (Yadagiri, Prasad & Satsangi, 1979). Discovery and species In 1924, Heber Longman, self-trained paleontologist at (and later director of) the Queensland Museum in Brisbane, learned of a large fossil reptile skeleton exposed in the Walloon Coal Measures at Durham Downs near Roma in southern inland Queensland. The station manager, Arthur Browne, forwarded fragments of bone to Longman, and was honoured with the dinosaur's specific name ''brownei''. The initial collection was of 22 tail ...
