Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Jurassic shopping experience:

1. Compare - without doubt the biggest advantage that the Jurassic offers shoppers today is the ability to compare thousands of Jurassic at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Jurassic? Wrong! If the Jurassic is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Jurassic then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Jurassic? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Jurassic and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Jurassic wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Jurassic then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Jurassic site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Jurassic, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Jurassic, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

The Jurassic Period (geology) is a major unit of the geologic timescale that extends from about 199.6 ± 0.6 annum (million years ago) to 145.4 ± 4.0 Ma, the end of the Triassic to the beginning of the Cretaceous. As with other geologic periods, the rock beds that define the start and end of the period are well identified but the exact dates are uncertain by 5 - 10 million years. The Jurassic constitutes the middle period of the Mesozoic era, also known as the "Age of Dinosaurs". The start of the period is marked by the major Triassic-Jurassic extinction event extinction event.

The Jurassic was named by Alexandre Brogniart for the extensive marine limestone exposures of the Jura Mountains, in the region where Germany, France and Switzerland meet.

Divisions The Jurassic period of time is usually broken into Early Jurassic, Middle Jurassic, and Late Jurassic subdivisions, also known as Lias, Dogger and Malm. The corresponding terms for the rocks are Lower, Middle, and Upper Jurassic. The faunal stages from youngest to oldest are:

{]||-|  Tithonian)|-|  [Kimmeridgian| (161.2 ± 4.0 – 155.7 ± 4.0 Ma)|-| [Middle Jurassic]| (164.7 ± 4.0 – 161.2 ± 4.0 Ma)|-|  [Bathonian| (171.6 ± 3.0 – 167.7 ± 3.5 Ma)|-|  [Aalenian||-|  [Toarcian| (189.6 ± 1.5 – 183.0 ± 1.5 Ma)|-|  [Sinemurian| (199.6 ± 0.6 – 196.5 ± 1.0 Ma)|}

Paleogeography .During the early Jurassic, the supercontinent Pangaea broke up into the northern supercontinent Laurasia and the southern supercontinent Gondwana; the Gulf of Mexico opened in the new rift between North America and what is now Mexico's Yucatan Peninsula. The Jurassic North Atlantic Ocean Ocean was relatively narrow, while the South Atlantic did not open until the following Cretaceous Period, when Gondwana itself rifted apart.http://www.scotese.com/late1.htm The Tethys Ocean closed, and the Mediterranean Basin basin appeared. Climates were warm, with no evidence of glacier. As in the Triassic, there was apparently no land near either pole, and no extensive ice caps existed.

The Jurassic geological record is good in western Europe, where extensive marine sequences indicate a time when much of the continent was submerged under shallow tropical seas; famous locales include the Jurassic Coast World Heritage Site and the renowned late Jurassic lagerstätten of Holzmaden and Solnhofen limestone.http://www.urweltmuseum.de/Englisch/museum_eng/Geologie_eng/Tektonik_eng.htm In contrast, the North American Jurassic record is the poorest of the Mesozoic, with few outcrops at the surface.http://www.nationalatlas.gov/articles/geology/legend/ages/jurassic.html|map] Though the Epeiric Sea Sundance Sea left marine deposits in parts of the northern plains of the United States and Canada during the late Jurassic, most exposed sediments from this period are continental, such as the alluvium deposits of the Morrison Formation.

The first of several massive batholiths were emplaced in the northern American cordillera beginning in the mid-Jurassic, marking the Nevadan orogeny.Monroe and Wicander, 607. Important Jurassic exposures are also found in Russia, India, South America, Japan, Australasia, and the United Kingdom.

Fauna Aquatic and marine and attached mytilid bivalves on a Jurassic limestone bedding plane in southern Israel.During the Jurassic, the primary vertebrates living in the seas were fish and marine reptiles. The latter include ichthyosaurs, plesiosauria and marine crocodilia, of the families Teleosauridae and Metriorhynchidae.

In the invertebrate world, several new groups appeared, including rudists (a reef-forming variety of bivalvia) and belemnites. The Jurassic also had diverse encrusting and boring (sclerobiont) communities (see Taylor & Wilson, 2003), and it saw a significant rise in the bioerosion of carbonate shells and hardgrounds. Especially common is the ichnotaxa (trace fossil) Gastrochaenolites.

Terrestrial , Diplodocus, Brachiosaurus and some little pterosaurs.On land, large archosaurian reptiles remained dominant. The Jurassic was the golden age of the great sauropods—Camarasaurus, Diplodocus, Brachiosaurus, and many others—that roamed the land late in the period; their mainstays were either the prairies of ferns, palm-like cycads and bennettitales, or the higher coniferous growth, according to their adaptations. They were preyed upon by large theropods (Ceratosaurus, Megalosaurus, and Allosaurus). All these belong to the 'lizard hipped' or saurischian branch of the dinosaurs.

During the Late Jurassic, the first Aves Evolution from small coelurosaur dinosaurs. Ornithischian dinosaurs were less predominant than saurischian dinosaurs, although some like stegosaurs and small ornithopods played important roles as small and medium-to-large (but not sauropod-sized) herbivores. In the air, pterosaurs were common; they ruled the skies, filling many ecological roles now taken by birds.

Flora The arid, continental conditions characteristic of the Triassic steadily eased during the Jurassic period, especially at higher latitudes; the warm, humid climate allowed lush jungles to cover much of the landscape.Haines, 2000. Conifers dominated the flora, as during the Triassic; they were the most diverse group and constituted the majority of large trees. Extant conifer families that flourished during the Jurassic included the Araucariaceae, Cephalotaxaceae, Pinaceae, Podocarpaceae, Taxaceae and Taxodiaceae.Behrensmeyer et al, 1992, 349. The extinct Mesozoic conifer family Cheirolepidiaceae dominated low latitude vegetation, as did the shrubby Bennettitales.Behrensmeyer et al., 1992, 352 Cycads were also common, as were ginkgos and tree ferns in the forest. Smaller ferns were probably the dominant undergrowth. Caytoniacea were another group of important plants during this time and are thought to have been shrub to small-tree sized.Behrensmeyer et al., 1992, 353 Ginkgo-like plants were particularly common in the mid- to high northern latitudes. In the Southern Hemisphere, podocarps were especially successful, while Ginkgos and Czekanowskiales were rare.Haines, 2000.,Behrensmeyer et al., 1992, 352
