Permian+Time+Period

= From when giant flying insects roamed the earth in the Carboniferous, to new emerging life in the triassic, the [|Permian Period] has been through a lot. In the Carboniferous period, the period before mine, reptiles evolved, giant insects, such as drangonflies came about. Over time, things changed... in the Permian period carniverous mammals appeard, new primitive conifers , and much more. Unfortunatly, something that would change all life on the planet at this time occured. The biggest [|mass extinction] EVER! 90% of all life died, only a small amount of organisms survived. Then after the Permian, in the Triassic period, life re-emerged. New life formed, such as dinos! To make a really long story short, the Permian went through a lot, but never went down without a fight. =

= All of the events in earths history effected how it is today. Our continets didn't start off the way they are today. First, they were in two, Gondwana and Laurasia. Soon after, those two crashed together to form Pangea. When this happened, the continent drifted northward, bringing it out of the = = = = coldness. The climate in the Permian period changed drastically. The climate got so hot, and humid, seas evaporated, putting and end to all of the aquatic life. With all this warm, summer type weather, land bacame tropical and dry. A result of this, is that deserts enlarge in tropical reigons. As you can tell in the Permian period, you finally get to see how our continents got to where they are today and the changes that could've effected the world permanently. =

= During this permian, there were many different life forms. some of them were plants, vertebrates and invertebrates. The vertebrates during the permian, were mostly reptiles, such as therapsids, lizards, snakes, archosausrus and the fiercest of them all, the Orphiacodon, and the Dimetrodon,who were carniverous beasts. The invertebrates living in this time were arthropods,corals, spiders, giant flying insects, scorpions and cockroaches. Over all, the life that was truly a real threat, were the synapsids. The reason for this is that they were the ancestors of mammals, or shall i say early mammals. In additon to carniverous reptiles and insects, there were many aquatic organisms. examples of these are, ammonoids, <range type="comment" id="507270">brachiopods, bryozoans and new, fresh water bony fish. The Permian period also had many new species of trees, some of these are primitive conifers, conifers are a type of plant that have seeds. = = =

= Even though the Appalachian Mountains started forming in the Silurian period, they are continuing to form in the Permian, but only the north parts of the Appalachians are still forming. <range type="comment" id="819896">Not many fossils have been discovered from the Permian Period, although they have found various fossilized eggs and footprints of organisms such as the dimetrodon. You may be wondering what is a fossil? It is evidence of living things turned to stone. Some fossils from the Permian period were found in Texas, South America, China, Nova Scotia. =
