Dinosaurs were immensely varied, and included both herbivores and carnivores.  Although many have been found in the fossil record, paleontologists expect that they have barely scratched the surface of the vast order that the dinosaurs encompassed.<ref>[http://news.nationalgeographic.com/news/2006/09/060905-dinosaurs_2.html Vast Majority of Dinosaurs Still to Be Found, Scientists Say], ''National Geographic''</ref>

Because the term only came into use in the 19th century, the [[Bible]] does not use the word "dinosaur."  However, they are alleged to be mentioned in numerous places throughout the biblical account. For example, the '''behemoth''' in [[Job]]  and the '''leviathan''' in [[Isaiah]] are sometimes said to be references to dinosaurs,<ref>Allan K. Steel, [http://www.creationontheweb.com/content/view/1799 Could Behemoth have been a dinosaur?], ''Journal of Creation'' vol. 15 No. 2 p. 42.</ref>  <ref>[http://www.answersincreation.org/job4041a.htm], ''Answers in Creation''</ref>, although others have claimed that Behemoth and Leviathan are references to a hippopotamus or elephant and a crocodile respectively.  Young-Earth creationists point out that the descriptions don't fit these creatures, including that hippopotamuses and elephants don't have a "tail like a cedar".

====Extinction====

According to most scientists, close to 65 million years ago, at the end of the [[Cretaceous]] period, and the beginning of what is called the [[Tertiary]] period, an event occurred which has come to be known as the [[K-T Event]].  This event would have 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 these 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 that the K-T Event was caused by the collision of a massive asteroid with the Earth, the dust and debris from which would have 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>  According to this view, the dinosaurs did not survive this cataclysm.<ref>[http://news.nationalgeographic.com/news/2002/08/0823_020823_asteroid.html Prehistoric Asteroid "Killed Everything"], ''National Geographic''</ref>  The dust from this impact is supposedly still visible as a line of metal of extraterrestrial origin and 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>[http://news.nationalgeographic.com/news/2003/03/0307_030307_impactcrater.html "Dinosaur-Killer" Asteroid Crater Imaged for First Time], ''National Geographic''</ref>

====An Explosion of new species ====

The mass 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.  According to this view, [[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 better conserve energy than the larger 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>
