The '''Jurassic''' [[period (geology)|period]] is part of the [[geologic system]] of classifying geologic formations.

{{stub}} According to geologists, who believe in the [[theory of evolution]] and/or an Earth that is billions of years old, the '''Jurassic''' epoch (period of time) dated from 203 million years ago to 146 million years ago. It is claimed by evolutionary scientists that this period was between the [[Triassic]] and before the [[Cretaceous]] Periods.<ref>http://www.talkorigins.org/faqs/faq-age-of-earth.html</ref>

The Jurassic period is part of the [[Mesozoic]] era, and is divided into Lower, Middle, and Upper epochs.  The Jurassic is preceded by Permian era and followed by the Cretaceous era.

[[Sauropods]] such as [[Diplodocus]] were supposedly common during this period.

The Jurassic was named from the [[France|French]] word (Jurassique) for the Jura mountains of [[Switzerland]].<ref>[http://www.etymonline.com/index.php?search=jurassic&searchmode=none Online Etymology Dictionary]</ref><ref>[http://www.geol.ucsb.edu/Outreach/TimeScale/jurassic.html Jurassic Period] (Department of Earth Science, University of California, Santa Barbara).</ref>

 

[[Young earth creationist]] scientists believe that the [[Theory of evolution|evolutionary]] [[Geology|geological]] timescale is in error. <ref>http://www.trueorigin.org/geocolumn.asp</ref><ref>http://www.icr.org/index.php?module=articles&action=view&ID=54</ref><ref>http://www.allaboutcreation.org/geologic-time-scale.htm</ref>  These scientists believe that the earth is young and has multiple lines of evidence from the field of geology showing that the earth is young. <ref>http://www.answersingenesis.org/home/area/faq/geology.asp</ref><ref>http://www.creationism.org/topbar/geology.htm</ref><ref>http://www.grisda.org/georpts/gr11.htm</ref><ref>http://www.nwcreation.net/geologylinks.html</ref><ref>http://globalflood.org/</ref> Also, young earth creationist scientists assert that there is an abundance of scientific arguments in addition to geology showing the earth and universe are both approximately 6,000 years in age.<ref>http://www.answersingenesis.org/home/area/faq/young.asp</ref><ref>http://www.answersingenesis.org/home/area/faq/astronomy.asp</ref><ref>http://www.icr.org/article/1842/</ref>  In addition, these scientists have a number of arguments against the position of an extremely old age for the earth and the universe.<ref>http://www.answersingenesis.org/home/area/faq/dating.asp</ref><ref>http://www.answersingenesis.org/home/area/faq/astronomy.asp</ref><ref>http://www.apologeticspress.org/modules.php?name=Read&cat=1&itemid=22</ref>

Under the uniformitarian dates assigned by secular geologists, it represents approximately the period of Earth's history from 200 million years ago to 145 million years ago.<ref>Gradstein, F.M., and Ogg, J.G.,[http://www.stratigraphy.org/scale04.pdf Geologic Time Scale 2004 – Why, How, and Where Next!]</ref> Young Earth creationists reject these dates (see [[geologic system]]).
