-'''Dinosaurs''' were [[reptile|reptilian]] creatures which are now generally believed to be extinct.
-They were known for their large size, although some species weighed just a few ounces.
-The word ''dinosaur'' was coined in 1841 by [[Richard Owen]]<ref>Grigg, Russell, [http://creationontheweb.com/content/view/1956/ Dinosaurs and dragons: stamping on the legends], ''Creation''
-(3):10–14, June 1992</ref>, from the Greek words for "terrible lizard", and reflected the creatures' large size and fearsome appearance to the early paleontologists.
-==Description==
-Dinosaurs are classified into two orders based upon differences in pelvic structure: ''Saurischia'' ("lizard-hipped"), in which the ''pubis'' is pointed forward and down; and ''Ornithischia'' ("bird-hipped"), in which the ''pubis'' is pointed towards the rear.
-===''Saurischia''===
-Herbivorous species were almost all quadrupedal.  They carried peg-like teeth which cut, rather than chewed, plant material; grinding of food was aided by gastroliths.  Carnivorous species were exclusively bipedal.
-*Sauropoda
-::Species of this infraorder are characterized by long necks and tails, barrel-shaped bodies, and column-like legs.  In three families (notably Diplodocidae, Brachiosauridae, and Titanosauroidea) there are species which are of extreme size, in excess of 125 feet in length and 100 tons, making them the largest animals to have walked the earth.
-:::''[[Apatosaurus]]''
-:::''[[Brachiosaurus]]''
-:::''[[Ultrasaurus]]''
-:::''[[Seismosaurus]]''
-:::''[[Argentinosaurus]]''
-:::''[[Diplodocus]]''
-*Theropoda
-::Exclusively bipedal; forearms meant for grasping or holding.  Fossil evidence for several species indicate pack hunting.
-:::''[[Coelophysis]]''
-:::''[[Ornithomimus]]''
-:::''[[Allosaurus]]''
-:::''[[Tyrannosaurus]]''
-:::''[[Deinonychus]]''
-:::''[[Velociraptor]]''
-:::''[[Giganotosaurus]]''
-===''Ornithischia''===
-Species of this group were all herbivorous; most were quadrupedal.  Front teeth were lacking, while a predentary bone was present in the front of the lower jaw.  Several species (mainly within ''Ceratopsia'') had a distinctive parrot-like beak.
-*Ceratopsia
-::Species of this infraorder carried one or more horns on their heads, as well as a shield-like frill to protect the neck.

-:::''[[Pachyrhinosaurus]]''
-:::''[[Torosaurus]]''
-:::''[[Protoceratops]]''
-:::''[[Styracosaurus]]''

-:::''[[Euoplocephalus]]''
-:::''[[Edmontonia]]''
-*Ornithopods
-::Large, herd-dwelling dinosaurs that could run bipedaly.  Several species had a "boss" of bone on their heads (Pachycephalosaurs) which may have been used for head-butting similar to bighorn sheep; others a crest of bone (hadrosaurs) which may have been sound resonators.

-==Highlights of the history of dinosaur paleontology==
-[[Image:Osborn.jpg‎‎|200px|thumb|right|[[Henry Fairfield Osborn]]]]
-In the United States during the 1900s, the public imagination was caught by the discoveries of [[Henry Fairfield Osborn]] (1857-1935) and the great competitive dinosaur hunters, [[Edward Drinker Cope]] (1847-1897) and [[Othniel Charles Marsh]] (1831-1899). Exploring in Wyoming, Colorado, and New Mexico, they found numerous fossil dinosaurs. Their museums worked out the techniques for mounting and displaying them.
-Osborn was a proponent of ''orthogenesis,'' as were many paleontologists up through the middle of the twentieth century. These paleontologists interpreted the fossil record as showing sustained, continuing, unidirectional trends in [[Theory of evolution|evolution]], which they felt required some kind of driving principle in addition to natural selection. As the author of an encyclopedia article on variation and selection put it in 1911,
-:Selection cannot create the materials on which it is supposed to operate... Both sides concur in the position assumed by Darwin, that the word "chance" in such a phrase as "chance variation" does not mean that the occurrences are independent of natural causation and so far undetermined, but covers in the first place our ignorance of the exact causation.... No doubt a large amount of variation is truly indefinite, so that many meaningless or useless variations arise... But there are several directions in which the field of variation appears to be not only limited but defined in a certain direction.... When beetles, or medusae, or cats vary, the range of possible variation is limited and determined by the beetle, medusa or cat constitution, and any possible further differentiation or specialization must be in a sense at least orthogenetic - that is to say, a continuation of the line along which the ancestors of the individual in question have been forced. Darwin himself showed that different species in a genus, or varieties in a species, tended to show parallel variations.<ref>Mitchell, Peter Chalmers (1911), ''Variation and Selection,'' ''Encyclopædia Britannica, 11th edition,'' volume 27 (TON-VES), p. 906</ref>
-[[Roy Chapman Andrews]] (1884–1960), said to be the prototype for the fictional Indiana Jones, is famous for his discovery of fossil dinosaur eggs in Outer Mongolia.
-In the 1970, Robert Bakker catalyzed a new era of dinosaur paleontology with evidence that dinosaurs were fully warm-blooded ([[endotherms]]) and fast-moving.<ref>Benton, Michael J. (2000), ''Vertebrate Paleontology'' [http://books.google.com/books?vid=ISBN0632056142&id=PQuKO7xqjNQC&pg=PA217&lpg=PA217&dq=%22robert+bakker%22&sig=imoHNyurTTCpztNV0Pp2EU7Fj6c p. 217]</ref>
-==Dinosaur Species==
-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 superorder 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>
-== Different Perspectives ==
-Ever since the discovery of dinosaur fossils, there has been debate about whether and how dinosaurs fit into the history of life on Earth. Young-Earth creationists reject the [[uniformitarian]] time-scale, and therefore believe that humans and dinosaurs co-existed. Creationists also reject the now-popular idea that dinosaurs evolved into birds.
-===Creationary Perspective===
-[[Image:Michelangeloflood.jpg|thumb|250px|left|''The [[Great Flood|Flood]]'', by [[Michaelangelo]], detail from the [[Sistine Chapel]], 1509.]]
-[[Young earth creationists]] believe, from the biblical account, that dinosaurs were created on day 6 of the [[creation week]]<ref>''Genesis'' 1:25</ref> approximately 6,000 years ago, along with other land animals, and therefore co-existed with humans.
-As such, they reject the [[Theory of Evolution]] and the beliefs of evolutionary scientists about the age of the earth.
-They believe that dinosaurs lived in harmony with other animals, (probably including in the [[Garden of Eden]]) eating only plants<ref>''Genesis'' 1:29-30</ref>; that pairs of each dinosaur [[kind]] were taken onto [[Noah's Ark]] during the [[Great Flood]] and were preserved from drowning<ref>[http://www.creationontheweb.com/content/view/3967/ Were dinosaurs on Noah’s Ark?], ''Creation Ministries International''</ref>; that many of the fossilized dinosaur bones originated during the mass killing of the Flood<ref>Carl Wieland, [http://www.creationontheweb.com/content/view/219/ Dinosaur bones—just how old are they really?], ''Creation'', vol. 21 No. 1 p. 54</ref>; and that possibly some descendants of those dinosaurs taken aboard the Ark are still around today.<ref Name="Today">Robert Doolan, [http://www.creationontheweb.com/content/view/833/ Are dinosaurs alive today?], ''Creation'', vol. 15 No. 4 p. 12.</ref>
-They use [[archaeological]], [[fossil]], and documentary evidence to argue that dinosaurs co-existed with mankind until at least relatively recent times.
-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 ====
-Creationists reject the "Great Impact Theory", pointing out multiple problems with this theory. <ref>Jonathan Sarfati, [http://www.creationontheweb.com/content/view/2426 Did a meteor wipe out the dinosaurs?].</ref>
-Creationists assert that evolutionists are frequently coming out with  a "New Theory of Dinosaur Extinction" and that their theories are laden with false assumptions. <ref>Michael Matthews, [http://www.answersingenesis.org/docs2002/1115dinosaur.asp Dinosaur demise theory, version #451], ''Answers in Genesis''</ref> It is worth noting, however, that more and more of these theories are being harmonized with one another.<ref>[http://www.spaceref.com/news/viewpr.html?pid=21082 More Than a Meteor Likely Killed Dinosaurs 65 Million Years Ago], ''SpaceRef.com''</ref>
-====Dinosaur-like creatures in history and modern sightings====
-Creationists cite a number of reasons to believe that dinosaurs have existed until relatively recent times, and perhaps still survive.
-[[Image:AZ_RockArtDino1a.jpg‎|right|150|thumb|right|Charles W. Gilmore, Curator of Vertebrate Paleontology with the United States National Museum, examined an ancient pictograph which he claimed portrays dinosaurs and man coexisting]]
-* There have been a number of claimed sightings of dinosaur-like creatures.
-** A thousand people reported seeing a dinosaur-like monster in two sightings around Sayram Lake in Xinjiang according to the Chinese publication, China Today.<ref name="Today" />
-** Locals in the Congo have reported a creature they name ''Mokele-mbembe''<ref name="Today" /><ref>[http://www.mokelembembe.com/ Mokele-mbembe The Living Dinosaur!]</ref>, and from its description it appears to be a small plant-eating dinosaur.  The reports have been taken seriously enough that a biologist from the [[University of Chicago]] has made several expeditions to find the creature.  Another biologist has reported seeing the creature.<ref name="Today" />
-** Dinosaur-like creatures have been seen by several people in two different parts of [[Papua New Guinea]] since 1990.<ref>Anon., [http://creationontheweb.com/content/view/381 A living dinosaur?], ''Creation'' 23(1):56, December 2000.<br />Irwin, Brian, [http://creationontheweb.com/content/view/5847 Theropod and sauropod dinosaurs sighted in PNG?] 1st July, 2008 (Creation Ministries International).</ref>
-* There are drawings of creatures resembling dinosaurs.
-** An expedition which included Charles W. Gilmore, Curator of Vertebrate Paleontology with the United States National Museum, examined an ancient pictograph which he claimed portrays dinosaurs and man coexisting.<ref>[http://www.creationism.org/swift/DohenyExpedition/Doheny01Main.htm Doheny Scientific Expedition, Hava Supai Canyon, Arizona], ''Creationism.org''</ref><ref>[http://www.christiancourier.com/articles/read/the_hava_supai_dinosaur_carving The Hava Supai Dinosaur Carving], ''ChristianCourier.com''</ref>.
-** The [[Nile Mosaic of Palestrina]], a second century piece of art, is said to appear to be a piece of artwork that shows a dinosaur and man coexisting. <ref>[http://www.s8int.com/dinolit2.html Dinosaurs in Literature, Art & History-- Page 2], ''s8int.com''</ref>
-** Engravings in the floor of [[Carlisle Cathedral]] appear to be of dinosaurs.  They are on the tomb of bishop Richard Bell, who died in 1496.<ref>See picture on page 241 of Batten, Don, et. al., 2007, ''The Creation Answers Book''.</ref>
-* Creatures matching dinosaurs and similar creatures have been described by various people groups.
-** The description of the "[[Thunder bird]]" of [[American Indian]]s matches the descriptions of [[pterosaur]]s.<ref name="Today" />
-* Descriptions of [[dragon]]s are widespread and match descriptions of dinosaurs, suggesting that dragons were real creatures and were actually dinosaurs.
-** The World Book Encyclopedia states that: "The [[dragon]]s of legend are strangely like actual creatures that have lived in the past. They are much like the great reptiles [dinosaurs] which inhabited the earth long before man is supposed to have appeared on earth." <ref>Quoted in [http://www.creationscience.com/onlinebook/FAQ25.html What about the Dinosaurs?], ''CreationScience.com''</ref>.  Dragons exist in the folklore of many European and Asian cultures.<ref name="WB2000">''Dragon'' entry in World Book Millennium 2000 CD ROM</ref>  World Book Encyclopedia says, "In Europe, dragons are traditionally portrayed as ferocious beasts that represent the evils fought by human beings.  But in Asia, especially in China and Japan, the animals are generally considered friendly creatures that ensure good luck and wealth."<ref Name="WB2000" />
-** Dragons appear in the flag of [[Wales]], in traditional [[China|Chinese]] [[New Years' Day]] celebrations, and in the Chinese [[calendar]].  Every other creature on the calendar is a real creature.
-[[Image:Palestrina1.jpg|right|thumb|A portion of the artwork the [[Nile Mosaic of Palestrina]]]]
-* That dinosaurs are not known from the fossil record above the [[Cretaceous]] strata is not reason to believe that they have not survived until more recent times.
-** Living specimens of orders of animals that were believed to have been extinct for millions of years have been found before, such as the Diatomyidae Squirrel <ref>[[Diatomyidae]] Squirrel [http://news.softpedia.com/news/They-Thought-It-Went-Extinct-11-Million-Years-Ago-19557.shtml]</ref>, the [[Wollemi Pine]] <ref>Wollemi Pine ''Biotechnology Australia'' [http://www.biotechnologyonline.gov.au/enviro/wollemi.cfm]</ref> and the [[Coelacanth]] <ref>Sulawesi Coelacanth. ''University Of California, Berkeley''[http://www.ucmp.berkeley.edu/vertebrates/coelacanth/coelacanths.html]</ref> <ref>More on the Coelacanth ''marinebio.org''[http://marinebio.org/species.asp?id=54]</ref>.
-* The recent dinosaur tissue find is a strong rebuttal of the claim that dinosaurs lived millions of years ago. <ref>Carl Wieland, [http://www.creationontheweb.com/content/view/3042 Still soft and stretchy], ''Creation Ministries International''</ref>
-<!-- The Coelacanth are from a group that had previously been thought to have rudimentary limbs and so be the ancestor of land creatures, but this idea was dropped when living Coelacanths were discovered.<ref>[http://www.users.bigpond.com/rdoolan/coelacanth.html Coelacanth: the world’s oldest fish?]</ref>  Biologists see this as merely a minor adjustment to the story of evolution. -->
-==== Dinosaurs and birds ====
-Creationists contend that the idea that birds are descendants of dinosaurs is not demonstrated by the evidence <ref>[http://www.creationontheweb.com/content/view/3833/106/ Bird evolution?], ''Creation Ministries International''</ref> <ref>Andy McIntosh, [http://www.creationontheweb.com/content/view/540/ 100 years of airplanes—but these weren’t the first flying machines!], ''Creation'' vol. 26 No. 1 p. 44</ref>, and that the dinosaur-bird connection is even disputed by some evolutionists.
-In his article, "Fifteen ways to refute materialistic bigotry", Dr. [[Jonathan Sarfati]] wrote regarding dinosaurs being descendants of birds:
-{{cquote|“The same logic applies to the dinosaur-[[bird]] debate. It is perfectly in order for creationists to cite [[Alan Feduccia|Feduccia]]’s devastating criticism against the idea that birds evolved ‘ground up’ from running dinosaurs (the cursorial theory). But the dino-to-bird advocates counter with equally powerful arguments against Feduccia’s ‘trees-down’ (arboreal) theory. The evidence indicates that the critics are ''both'' right — birds did not evolve either from running dinos or from tree-living mini-crocodiles. In fact, birds did not evolve from non-birds at all!<ref>Jonathan Sarfati, [http://www.creationontheweb.com/content/view/2610 15 ways to refute materialistic bigotry], ''Creation Ministries International''</ref>}}
-Creationists also cite the evolutionist and [[atheism|atheist]] [[Ernst Mayr]]<ref>Matthews, Michael, [http://www.answersingenesis.org/docs2003/1208mayr.asp 99 and still fighting God], 8th December, 2003 (Answers in Genesis).</ref> who stated the following:
-{{cquote|“It must be admitted, however, that it is a considerable strain on one’s credulity to assume that finely balanced systems such as certain sense organs (the eye of vertebrates, or the bird’s feather) could be improved by random mutations." <ref>[http://www.creationscience.com/onlinebook/ReferencesandNotes10.html In the Beginning: Compelling Evidence for Creation and the Flood], ''Center for Scientific Creation''</ref>}}
-The March 2003 issue of ''Scientific American'' is also cited by creationists:
-{{cquote|Of all the body coverings nature has designed, feathers are the most various and the most mysterious...The origin of feathers is a specific instance of the much more general question of the origin of evolutionary novelties--structures that have no clear antecedents in ancestral animals and no clear related structures (homologues) in contemporary relatives. Although evolutionary theory provides a robust explanation for the appearance of minor variations in the size and shape of creatures and their component parts, it does not yet give as much guidance for understanding the emergence of entirely new structures, including digits, limbs, eyes and feathers...." <ref>Michael Matthews, [http://www.answersingenesis.org/docs2003/0313sciam.asp Scientific American admits creationists hit a sore spot], ''Answers in Genesis''</ref> <ref>[http://www.sciam.com/article.cfm?articleID=000CD7F6-B16F-1E41-89E0809EC588EEDF Which Came First, the Feather or the Bird?], ''Scientific American''</ref>}}
-Creationists also assert that the comparative anatomy analysis done by evolutionists comparing bird bones and dinosaur bones is flawed. <ref>Dr. David N. Menton, [http://www.answersingenesis.org/docs2005/0328discovery.asp "Ostrich-osaurus" Discovery?], ''Answers in Genesis''</ref>
-===Evolutionary/Old Earth Perspective===
-The view of [[Theory of evolution|evolutionists]] and others who accept the uniformitarian timescale is that dinosaurs existed on earth from 230 million years ago to 65 million years ago. In this view, the entire population of dinosaurs were wiped out by a mass extinction event (usually thought to be an asteroid) about 65 million years ago.
-This precludes humans and dinosaurs co-existing.
-====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 claimed 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>  A layer of rock containing high concentrations<!-- "High", or just "higher than normal"? --> of [[Iridium]], a metal that is extremely rare on earth but common in asteroids, is said to be due to the vaporization and then fall of dust from the meteorite's impact, and its compression within the subsequent geological record.<ref>''Ibid''</ref>The evidence of a large impact crater can be found in rocks of the [[Yucatán]] Peninsula of the supposed age of this layer.<ref>[http://news.nationalgeographic.com/news/2003/03/0307_030307_impactcrater.html "Dinosaur-Killer" Asteroid Crater Imaged for First Time], ''National Geographic''</ref> <ref>http://www.ucmp.berkeley.edu/education/events/cowen1b.html</ref>
-Creationists assert that the assumptions underpinning the methods used by modern geologists are incorrect, and even though the validity of a large impact is accepted, this does not consitute proof that the impact caused the extinction of the dinosaurs&mdash;although the abundance of dinosaur fossils in rocks found higher in the rock layers than the impact is drastically less than their abundance in rocks lower down.{{fact}}
-====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 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 fossils (claimed to be dinosaurs) have been discovered, and evolutionary scientists claim the similarity in the bone structure between birds and dinosaurs show that modern birds are a descendants of dinosaurs.  This is often cited as an example of [[macroevolution]].<ref>[http://news.nationalgeographic.com/news/2004/10/1006_041006_feathery_dino.html New Dinosaur Discovered: T. Rex Cousin Had Feathers], ''National Geographic''</ref> Cladists place modern birds within the clade dinosauria, meaning that they consider all bird species today as, technically, dinosaurs.<ref>[http://tolweb.org/Dinosauria/14883/1999.01.01 Tree of Life Web Project.] 1999. Dinosauria. Version 01 January 1999 (temporary). Accessed 30 May 2007.</ref>
-==Dinosaur fossils and Human Fossils and Geological Strata ==
-Some evolutionary scientists assert that if human bones aren’t found with dinosaur bones, then dinosaurs and man didn’t live together.<ref name="HaD">Hodge, Bodie, [http://www.answersingenesis.org/articles/am/v1/n1/humans-and-dinosaurs If humans and dinosaurs lived together, why don’t we find human fossils with dinosaur fossils?] ''Answers'' 1(1):52, May 2006.</ref><ref>[http://www.talkorigins.org/indexcc/CH/CH710.html Claim CH710] (The TalkOrigins Archive)</ref>
-Creation scientists point out that this is a false assumption; if human bones aren’t found buried with dinosaur bones, it simply means they weren't buried together.<ref name="HaD" />
-Evolutionists point out that [[radiometric dating]] of rocks containing dinosaur bones shows them to have formed between 65 million years ago and 250 million years ago, whereas rocks with human bones in them are dated as being much newer (less than 5 million years old). Young Earth Creationists believe that these methods of dating rocks provide false results, and therefore reject this argument.
-Creationists note that the fossil record contains mainly marine organisms and that a small sliver of the fossil record contains vertebrates and thus assert that we shouldn't expect to find many human fossils at all.<ref name="HaD" />
-Moreover, as the biblical [[Great Flood|Flood]] would be a marine catastrophe, it would be expected that marine fossils would dominate the fossil record.  This is in fact what we find.<ref name="NAB">Hodge, Bodie, [http://www.answersingenesis.org/PublicStore/pdfs/SampleChapter/10-2-267.pdf Why Don’t We Find Human & Dinosaur Fossils Together?] (chapter 13 of the New Answers Book), 2006.</ref>
-Approximately 70% of the Earth is covered in salt water which would also explain the dominance of marine fossils. In addition, creation scientists assert there may have been a small pre-flood human population and that massive amounts of flood sediment are why we haven’t found human fossils in pre-biblical flood sediments.<ref name="NAB" />
-Also, creation scientists point out that we don't find human bones buried with [[coelacanth]]s yet humans and coelacanths coexist today.<ref name="HaD" />
