Dinosaur Fossils in Antarctica :: Anthropology Essays Paleontology Papers

Dinosaur Fossils in AntarcticaMillions and millions of eld ago the continents lay together as one and only(a) super-continent known as Pangea. As time went on and the plates underneath the cosmos began to separate, the continents land moved towards the poles where glaciation occurred. Glaciation is the process in which glaciers were leveled during the ice age. Glaciation causes a drop in temperature which in turn causes water to freeze and form many layers of ice (http//palaeo.gly.bris.ac.uk/Palaeofiles/Permian/intro.html, 1). Due to this layering of ice that has occurred at both poles it has not been easy to discover new dinosaur fossils. However, in a press unveil of the National Science Foundation researchers, working in cardinal clear-cut sites of Antarctica found what seem to be fossil remains of two several(predicate) dinosaurs that had previously never been introduced to the world of science (http//www.nsf.gov/od/lpa/newsroom/pr.cfm?ni=52, 1).The two different din osaurs were found in opposite areas of Antarctica. The first dinosaur found was bring out on the James Ross Island off the coast of the Antarctic Peninsula while the trice dinosaur was discovered on the Antarctic interior on a masses elevating nearly 3900 meters near the Beardmore Glacier. The discovery of these two dinosaurs was important for a twain reasons. First off, dealing with the dinosaur carnivorous dinosaur found off the James Ross Island the discovery was important was because not many dinosaurs from the Cretaceous Time Period had been uncover in Antarctica. The second reason the finding of this fossil was important was because in the James Ross region of the Antarctic Peninsula there had previously only been vi uncovered dinosaur fossils and this finding adds to that number. Lastly, it is a very uncommon to find a dinosaur that was so well preserved considering it died roughly 70 million years ago. In order for it to be in such good execute it had to float o ut to sea and lie in the bottom of what was whence an extremely shallow part of the Weddell Sea (www.sciencedaily.com, 2). When it comes to the plant-eating dinosaur found on the interior of Antarctica the discovery of this dinosaur was also important because of its rarity. William Hammer, who led the research group said from Augustana College in Rock Island, Illinois said, This site is so far aloof geographically from any site near its age, its clearly a new dinosaur to Antarctica.
