PANGEA is was just a big land mass and a lot of water arond it. I am sure there wasnt a lot of living creatures cause them dang dinosaurs done ate everything but themselves and than i am not even sure about that

How were the tracks formed\n\nThe Johnson farms dinosaur tracks lie within the Moenave formation which includes layers of sandstone, mudstone, and shale. The tracks were found at the bottom of a three-foot thick layer of sandstone overlaying mudstone. The fossil evidence indicates that the Johnson farm was located along the margins of a shallow saline lake 200 million years ago. As the water receded, dinosaurs walking through the leftover clay left impressions of their feet including scales of their skin and prints of their toes. As the mud hardened, cracks around the tracks formed. Eventually the lake level rose and buried the tracks with sand and silt. Over time the sand hardened and became sandstone thus preserving the dinosaur tracks. Within the three-foot sandstone blocks are several track-forming layers.

It is a huge question, but in general you would want to check paleoclimatology (for example, glaciation of Antarctica after opening of Drake and Tasmania passages), paleontology/biogeography (distribution of fossils and ancient migration of various animal groups).\n\nThere is a page with lecture notes which is very shorthand but touches on most things you may want to check:\nhttp://jersey.uoregon.edu/~mstrick/RogueComCollege/RCC_Lectures/ConDrift_PlateTec.html\n\nAnother link that touches on the subject:\nhttp://pgap.uchicago.edu/PGAP2000-1.html

This is a great way to begin understanding the different forces that shape the land.  It is important to remember how the rocks came to be found, Metamorphic rocks from Michigan that may have been dug up from a deep quarry or found on the surface exposed by glacial action.  In N Carolina they could be sedimentary rocks exposed by water erosion.  In Florida they could very likely be calcium carbonate deposited by ancient coral reefs.  A simple understanding of these and other rock forming processes would make a prize winning 4th grade report.  Good Luck!

Dinosaurs are archosaurs, a group that includes crocodiles, birds, and all the descendants of their most recent common ancestor. The closest relatives of dinosaurs, which evolved with them in the Middle and Late Triassic (about 225 million years ago), include the flying pterosaurs and agile, rabbit-sized forms such as Lagosuchus and Lagerpeton. The common ancestor of all these forms was small, lightly built, bipedal, and probably an active carnivore or omnivore. Somewhat larger, with skulls ranging 15–30 cm (6–12 in.) in length, were Eoraptor and Herrerasaurus from the Late Triassic of Argentina, and Staurikosaurus from the early Late Triassic of Brazil. They were thought to be primitive saurischian dinosaurs, but it was later determined that they were outside the group formed by Saurischia plus Ornithischia, a view generally followed. In reconsidering these genera plus the more recently discovered Eoraptor, it has been argued that all three are both saurischians and theropods. However, they lack some features of both groups, so their position remains controversial. This testifies to a burst of evolutionary change at this very interesting time in vertebrate history, and it shows that there are a variety of taxa that are very close to the origin of dinosaurs. The first definite ornithischians and saurischians appear at almost the same time as these taxa, though dinosaurs remained generally rare and not very diverse components of terrestrial faunas until the beginning of the Jurassic Period (about 200 million years ago).

This is only a theory, no amount of evidence has proven it fact. The only way scientists verify it is through fossil records which show the existence of marine creatures and plants existing at one point in the middle of the dry land continents that we see today. Also, scientists believe that the continents were once one huge land mass that came into existence similar to the way Hawaii did (aka. with a lot of volcanic activity).

Neanderthal period if this is spelled right. Just about the time that the Jurassic period was about to end. This is the best guess I can give you.

In the Carboniferous Period, approximately 300 million years ago, what is today Saudi Arabia and vicinity was part of Pangea, and sort of adjacent to the Appalachian Mountains which is today part of America.  That's when vast swamps were formed, which originally provided the biomass for underground oil, draining into the Paleo-Tethys Sea.  Alas, beginning around the Jurassic Period, Pangea began to break up, forming the new Atlantic Ocean.  So, all that oil that originally belonged to America moved away, and by the time dinsosaurs became extinct, the mideast was being formed, and after a while Arabs were living on it, claiming the oil for themselves.  It's just not fair. \n\nCheck out the website about paleogeography.

"My short answer for the questions that need a lot of spaces for arguments. \n\n1) Good geological conditions that need oil accumulation. \n2) Good source rock preservation due to geographic and rich orgainism thriving conditions. Both fine once in the present Middle East during many million years ago. \n\nSome details are as follows \n\nIn order to reach to a satisfying answer of your question, it is important to appreciate the science of Plate Tectonics. \n\nIn geologic terms,a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root "to build." Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. \n\nThese blocks or plates have different properties and behave differently in response to its gliding surface and at the time of dynamic movements. The Earth what we observe now believed to be not the same throughout the geological time. It had changed its shapes and continents and had been mobilized geographically as well. Many scientific explanations have been presented to prove the theory. Presence of fossils of similar kind of plants and animals in diversified continents, thousands of miles apart, once fused, showed the evidence of plate movements. \n\nVarious continents of the Earth floated around the globe in the geologic past, such as, Africa and South America, India and Europe and Asia. Geological past could be as ancient as 2500 million years old to few thousand years ago. It implies that a continent at the equator now, must had been near the poles once in the past, may be several millions years before the past. Every climatic zones have their internal biologic and climatic activity. \n\nWhile studying Petroleum accumulation or deposits of hydrocarbon, keep in mind, the most important factors controlling the oil accumulation are, source rock, reservoir and trap. \n\nSource rock is closely and directly related to the biological activity of the given zone which will help to concentrate the organic matter at one place and afterward it becomes preserved if met appropriate conditions. Most of the areas now comprised of Arabian Peninsula including North Africa, Saudi Arabia, Iran and Iraq, were remained near the tropical areas between latitude 20 degree south to 20 degree north during Jurassic (135 million years) late Tertiary (10 million years). Biologic activity and productivity is the highest in these tropical and equatorial zones compare to the area lying near the poles. The rocks of the Jurassic and Cretaceous have been found good source and reservoir rocks throughout the Saudi Arabai, Yemen, Sudan Iraq and Iran. On the other hand reservoir rock particularly in the Paleozoic age are either deposited in the continental environments which have less prominent cement between the grains. Such rock are very porous and capable to store huge volume of oil and gas. Middle Eastern areas remained tectonically less active or passive and consequently much less breaking and destruction activity prevailed in that part of the Earth. \n\nIn summary, middle east has been encountered all the favourable conditions for the generation, preservation and accumulation of hydrocarbon during the geological history of the area. India has oil and gas because it has vast sedimentary basins in the west and east of the continent, both in offshore and land" (Syed Tariq Hasany).

There is few hints like same geology at diferernt geografic points related to the same period; \nSame fauna indicating same region or at leastthey migrated through some kind of bridge;\nObvious fit about the continents. \nWhat cause it is the tectonic movement. Dorsals have separated it and we still in movement there is measure about hom many inches we are far from Europe/AFrica and also to other continents. (Also Heigh of montains are changind)

OK, first geography is NOT geology *sigh*\n\nLook up carbon dating; you can either tell by the degradation of carbon or by basic layering (what's on the bottom is older than what's on the top).

These were Mesozoic marine reptiles. They lived during the Triassic, Jurassic, and into the middle and Late Cretaceous.\n\nHere is an authoritative site that describes the taxonomy, gives physical characteristics, environmental adaptations, and shows some photos. \n http://www.palaeos.com/Vertebrates/Units/210Eureptilia/300.html

Very roughly 2 billion years ago.  But you should be aware of two points. \n\nThe first is that the date is a matter of considerable debate and it could easily be half a billion years either side of that.\n\nThe second is that the transition was extremely slow, starting with the addition of oxygen by inorganic processes and then taking a massive leap with the evolution of oxygen producing autotrophs.
