Structural
The overwhelming scientific consensus is that dinosaurs lived from 230 million until 65 million years ago and that they are all currently extinct (however [[birds]] are considered by scientists to be descended from early [[therapod]] dinosaurs). They claim the [[fossil]] evidence supports this theory. Many Creationists dispute this, claiming that the dating methods used to judge the age of the fossils are not always precise and that there are gaps within the fossil record itself. Furthermore, because the Earth was created 6000 years ago (according to the word of the Bible) it would be impossible for the fossils to be that old. Ken Ham states the very reasonable theorey that Dinosairs were killed during the great flood, buried in mud and then fossilized. Ken Ham

==Dinosaurs through Science==
What follow are the perspectives on dinosaurs accepted by the vast majority of the scientific community, through use of the [[scientific method]], and taught at the United States' major research universities. Following any of the references in this section will lead to scientific treatment of the issue discussed.
===Dinosaur Speciation===
Dinosaur species were immensely varied, from herbivores to carnivores. Although many have been found in the fossil record, paleontologists expect that they have barely scratched the surface of the vast genus that the dinosaurs encompassed.<ref>National Geographic, http://news.nationalgeographic.com/news/2006/09/060905-dinosaurs_2.html</ref>
===Extinction===
[[Image:800px-KT_boundary_054.jpg|thumb|right|300px|Badlands near [[Drumheller, Alberta]] where erosion has exposed the KT boundary.]]Close to 65 million years ago, at the end of the [[Cretaceous]] period, and the beginning of what we call the [[Tertiary]] period, an event occurred which has come to be known as the [[K-T Event]]. This event obliterated most life on Earth, plunging the world into something that would now be likened to global nuclear winter, through which few extant species could survive. Although scientists dispute the nature of the K-T Event (selecting among any number of catastrophes that could have caused the significant global cooling that resulted), most find, based on strong geological evidence, that the K-T Event was caused by the collision of a massive asteroid with the Earth, the dust and debris from which shrouded the sky for thousands of years, cooling Earth considerably.<ref>Kevin O Pope, "Meteorite impact and the mass extinction of species at the Cretaceous/Tertiary boundary," Proceedings of the National Academy of Science, available at http://www.pnas.org/cgi/content/full/95/19/11028</ref> The dinosaurs did not survive this cataclysm.<ref>National Geographic, http://news.nationalgeographic.com/news/2002/08/0823_020823_asteroid.html</ref> Evidence of the dust that caused this long winter is still visible, though, as a line of metal of extraterrestrial origin is often visible in sediment worldwide, occurring as a result of the vaporization and then fall of dust from the meteorite's impact, and its compression within the subsequent geological record.<ref>''Ibid.''</ref> The crater is also visible.<ref>National Geographic, http://news.nationalgeographic.com/news/2003/03/0307_030307_impactcrater.html</ref>
===Cambrian Life Explosion===
The extinction of the dinosaurs removed a major food competitor, and predator, of smaller animals. As a result of a new "vacancy" in the food chain, following the [[K-T Event]], vast speciation occurred, as the evolutionary pressure of a new cold age propelled animal species to adapt or die out. What we now know as [[mammals]] were some of the main beneficiaries of this explosion: their fur allowed them to adapt to the cold, and their small size allowed them to conserve energy relative to the huge dinosaurs of the previous age.<ref>Bennet, Shostak, Jakotsky, "Life in the Universe," viewable at http://www.amazon.com/Life-Universe-Jeffrey-Bennett/dp/0805385770</ref>
===Dinosaurs and Birds===
As a number of feathered dinosaur fossils have been discovered, and the similarity in the bone structure between birds and dinosaurs, scientists contend that modern birds are a descendant of dinosaurs. This is cited as an example of [[macroevolution]].<ref>National Geographic, "New Dinosaur Discovered: T-Rex Cousin Had Feathers," http://news.nationalgeographic.com/news/2004/10/1006_041006_feathery_dino.html</ref>
==Dinosaurs and Creation==
What follow are religious perspectives on dinosaurs, offered by organizations such as "Answers in Genesis," or "Creation on the Web." Following any of the links associated with this section will lead to a treatment of the issue in line with Biblical literalism.

An alternate theory for the inclusion of dinosaurs within many cultures is the existence of fossils. Ancient people, unaware that the ancient fossils uncovered by erosion were of extinct animals, attributed the bones to living, magical creatures. This would explain the importance of dragons in Chinese culture - there are a large number of dinosaur and dragon fossils to be found in China.
