Dinosaurs (In Science) - Research study ExampleAs in moderns day nature nature abhors a vacuum (Aristotle, quoted by Link, 2011 ) and so dinosaurs developed to fit into every niche, large, sm every, carnivorous, herbivorous etc. It is possible to tell what each creature take in if their teeth atomic number 18 examined. Just as the teeth of dogs and cows argon very several(predicate), to suit their person diets, so the teeth of meat eating dinosaurs be very different from those of the vegetarians. They also carried an impressive begin of body part including such extras as scales, horns, collars and crests, what Viegas (2012) describes as Feathered, clawed and jaws,. So far, the remains of over 1,000 different dinosaur species sacrifice been identified from fossils though technically, birds are feathered dinosaurs, meaning dinosaurs arent really extinct at all. The incident that some dinosaurs have been found which are feathered adds emphasis to evolutionary ideas and the hyp othesis that birds are instantly descendants of some dinosaurs, an idea offshoot put forward as long ago as 1870 ( Stone 2010) brings to mind other scientific questions such as who are the predecessors of mankind. Some, although not all dinosaurs, are known as being bird hipped because of their particular anatomical features. They were . small, agile, and walked on two legs, conflicting some much larger relatives. One such example is the Lesothosaurus Diagnosticus, a medium sized herbivore, first discovered in Southern Africa, within the kingdom of Lesotho, in 1978 ( National Geographic, 2012). It is so bird comparable that it looks somewhat like a plucked bird. The dinosaurs were a highly diverse and successful group. They are a lot said to have lasted for far more than 100 one million million years, being the dominant from of life on land for some 160 million years, but if one includes birds then they are still around ( BBC, Science and personality Prehistoric Life, undate). Yet most of them did disappear, which has lessons perhaps for man , who acts as if the world belongs to him by right. Dinosaur remains are often found in association with rocks which can be dated to a particular time. These rocks are usually sedimentary rocks, formed during a great ancient flood , massive floods are often being mentioned in ancient legends in many civilizations, despite the fact that the oldest humanoids found have been dated to only 4.4 million years ago (Schmid, 2009). Perhaps people were describing another cataclysmic flood. If so that provide surely also be found in the geological record. According to Gilroy, most dinosaurs became extinct 65.5 million years ago, but it seems that there were survivors , and some dinosaur remains have quite recently been dated at some 700,000 years later (2011). So the picture isnt at all clear. There was not for instance just one massive extinction period , but two. Viegas, ( 2012) describes the Permian extinction, when 90 per cent of all life on earth was destroyed, the most devastating extinction of all time, from insects to plants. Marine creatures as comfortably as those on land were affected as well as amphibians and reptiles. Dinosaurs often had air sacs which enabled them to extend in poor air quality
