Brachiosaurus /ˌbrækiəˈsɔrəs/ is a genus of sauropod dinosaur from the Jurassic Morrison Formation of North America. It was first described by Elmer S. Riggs in 1903 from fossils found in the Grand River Canyon (now Colorado River) of western Colorado, in the United States. Riggs named the dinosaur Brachiosaurus altithorax, declaring it "the largest known dinosaur". Brachiosaurus had a proportionally long neck, small skull, and large overall size, all of which are typical for sauropods. However, the proportions of Brachiosaurus are unlike most sauropods - the forelimbs were longer than the hindlimbs, which resulted in a steeply inclined trunk. Also, while

In 1883, a sauropod skull was found near Garden Park, Colorado, at Felch Quarry 1, and was sent to Othniel Charles Marsh (of "Bone Wars" fame).[5] Marsh incorporated the skull into his skeletal restoration of "Brontosaurus" (now Apatosaurus).[5][20] It eventually became part of the collections of the National Museum of Natural History, as USNM 5730.[5] In the 1970s, when Jack McIntosh and David Berman were working on the issue of the true skull of Apatosaurus, they reevaluated the Garden Park skull as more similar to Camarasaurus.[21] It was described and recognized as a Brachiosaurus skull in 1998 by Kenneth Carpenter and Virginia Tidwell, intermediate in form between Camarasaurus and Giraffatitan brancai (then still considered to be B. brancai).[22] Because there are no overlapping parts between this skull and FMNH P 25107, it cannot be confidently assigned to a species,[5][22] so it is classified as Brachiosaurus

    Following her father’s death, Mary was the primary supporter of her mother Molly and her brother Joseph. Their poverty was dire enough that they were living off of parish relief for several years . So when Mary made her first significant discovery of a marine reptile related to dinosaurs that would be christened Ichthyosaurus, it was nothing more than a financial gain to them, as Mary and her family sold the creature’s bones to a local for 23 pounds . The fossil changed hands several times before eventually being sold to the British Museum where its significance was recognized. The Fossil Hunter by Shelly Emling emphasizes the importance of Mary’s early find. Emling’s book mentions how Sir Everard Home, Britain’s leading anatomist analyzed the fossil. The creature was so strange, he was unable to put it into a specific category. Despite its very fish-like anatomy, it also had bones around the eye socket previously only seen in birds . Home eventually gave an address concerning the fossil, but never gave Mary credit for finding it. And she was not given credit either during the time that the Ichthyosaurus was displayed in the Egyptian Hall in the British Museum…

    This unique species within the horned dinosaur group is given its name by it’s discoverer Wendy Sloboda. Related to Triceratops, it has a body similar to the extant rhinoceros. Wendiceratops pinhornensis was a quadruped. supported by its leaf-shaped teeth and cropping beak it is believed to be a herbivore. It was approximately 6 meters long and weighed over a ton. Wendiceratops dates back 79 million years ago, during the Late Cretaceous period. One of its distinctive features is its skull ornamentation. It has a decorated neck frill with forward protruding hook-like horns along the margin of its frill. This is unusual to early members of the horned dinosaur family. The significance of Wendiceratops lies in its nasal horn. Wendiceratops is the…

    By looking at the title do you know what it is about? The Tyrant Lizard king is actually the nickname of a dinosaur you probably do know which is, Tyrannosaurus Rex. The T. Rex was about Forty feet long, about fifth teen to twenty feet tall. Although the Tyrannosaurus Rex was big it was not the biggest dinosaur, compared to other dinosaurs he was quite small! Unlike what you may think, the T. Rex might not have been green; no one knows what color it was. The Tyrannosaurus Rex had a big head. The Tyrannosaurus Rex had two strong legs and two tiny little arms (Three feet long) each with two fingers. He also had a straight stiff tail that was good for giving it balance and for it to make quick turns. The T. Rex weighed…

    Othniel Charles Marsh then pointed out that Cope had but the skull of the dinosaur or the wrong end of its body, humiliated and embarrassed Cope. The rivalry between the two pushed each other to work harder on their research. There were many times where the two men were competing to describe the most new dinosaurs fossils. Sadly, this led to much rushing of the scientist and meant that there were times when the men would mix up different bones and even use a dinosaurs name one than once. The rivalry between the two men was still extremely positive on the study of paleontology. Before Cope and Marsh had started to research the fossils there were only eighteen dinosaurs known. Between Edward Drinker Cope and Othniel Charles Marsh they had named more than 130 new…

    Obudrodon Dicksoni

    • 29 Pages

    This thesis began as an investigation into evolution of the platypus family (Ornithorhynchidae, Monotremata), now known from both Australia and South America. The thesis broadened its scope with inclusion of non-ornithorhynchid Mesozoic monotremes from Lightning Ridge, NSW. This change in direction brought an unexpected result: a fossil mammal from Lightning Ridge investigated for this thesis (presumed to be monotreme: Flannery et al., 1995) appears to be a new and unique type of mammal. Specimens were procured through Queensland Museum (Riversleigh material); Australian Museum (Lightning Ridge material); and Museum of Victoria and the South Australian Museum (fossil ornithorhynchids). Specimens were examined under a light microscope and scanning electron microscope; specimens were photographed using light photography and a scanning electron microscope; and illustrations and reconstructions were done with a camera lucida microscope attachment and photographic references. Parsimony analysis utilised the computer programs PAUP and MacClade. Major conclusions: 1) analysis and reconstruction of the skull of the Miocene platypus Obdurodon dicksoni suggest this robust, large-billed platypus was a derived northern offshoot off the main line of ornithorhynchid evolution; 2) the well-preserved skull of Obdurodon dicksoni shows aspects of soft anatomy previously unknown for fossil ornithorhynchids; 3) two upper molars from Mammalon Hill (Etadunna Formation, late Oligocene, central Australia) represent a third species of Obdurodon; 4) the South American ornithorhynchid Monotrematum sudamericanum from the Paleocene of Argentina is very close in form to the Oligocene-Miocene Obdurodon species…

    In 1676, a partial femur of a Megalosaurus was discovered in England. This bone was massive and unfortunately, 17th century theologists couldn’t fathom a huge, reptile like animal from a time before theirs (Strauss). A professor from Oxford University identified it as the femur of a human giant but in 1824, William Buckland gave this genus its distinctive name. It took another twenty years for the famous paleontologist, Richard Owen, to convincingly identify the Megalosaurus as a dinosaur (Strauss). In 1820, the Iguanodon, which was first investigated by Gideon Mantell, was identified as the second dinosaur to have a formal genus name. Its numerous fossils stirred up a debate about whether or not these extinct reptiles actually existed (Strauss). Georges Cuvier and William Buckland made a joke out of the situation exclaiming that the bones belonged to a fish or rhinoceros. Richard Owen had another perspective that basically…

    Neanderthal Traumas

    Spearheaded by the Germans discovery of the skullcap and limbs, archaeologists gather information, make inferences, and use their imaginations to construct how things use to be. The conditions of the fossils let us know the kinds of conditions people/animals lived in. This can be problematic because for example, Neanderthal bones and deer bones were mixed together with some of the same marks. An archaeologist could have mixed up the bones and given the Neanderthal a characteristic of life that isn’t accurate to them. This could be the case for any fossil that isn’t easily identifiable and archaeologists have to use their “imaginations.”…

    Evolution is defined as the idea or scientific theory that was proposed by Charles Darwin. Darwin believed that all species changed and evolved by natural selection from the same common ancestors. Evolution simply means that a species undergoes genetic change over time. Over many generations a species can evolve into something different. These changes take place because of changes in DNA, which originated as mutations. Not all species evolve at the same rate. The theory of evolution does not prove that species will constantly evolve or how fast the species will change when it does (Park, 2008).…
