Steinmann septate pith pine fossil<br>People who have been to Turpan, the deepest feelings is above 40 degrees Celsius heat. There has been a "flaming" it? & Nbsp; & nbsp;<br> <br>& Nbsp; & nbsp; & nbsp; 2012, the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences researcher Wang, Ph.D. million that the ceremony, Professor, Missouri University of Science and Technology Professor Yang Wan et al., In Xinjiang discovered a "Steinmann septate pith pine" fossil, after two years of research, they restored the 255 million years ago,canada goose femme, Turpan - Hami Basin "cool past",piumini woolrich outlet,http://tuonela.s138.xrea.com/lightbbs/light.cgi?res=7132, where warm and humid, the annual average temperature in the 12 to 14 degrees Celsius, the average annual rainfall of 900 to 1240 mm. Related research recently published in the internationally renowned geoscience journal "paleogeography, paleoclimate, paleoecology" on.<br> <br>Modern Express reporter Hu Yumei<br> <br>Tree "tree" rings is not obvious<br> <br>"This is our research petrified wood." Wang's computer has a map, the figure of silicified wood fossils, about 15 cm in diameter.<br> <br>"It really is a tree of life 255 million years ago in the pine and cypress, now extinct. It should be very long, we found only a part of it." Wang said that their study is a fossil conifers, It lived what age, how it was dead? These can not know. To be sure, the tree of life in the Permian mass extinction 10 million years before the end of the Permian mass extinction, which belongs to "disappear" category.<br> <br>Wang Jun, they put the tree named "Steinmann septate pith pine", to commemorate the Chinese paleobotany and continental strata Andean pioneer research revolves Academy of Sciences. They fossils slice careful study under a microscope. Time has passed 255 million years, but the tree is still intact xylem cells,http://www.sugowaza.jp/reports/get/1/9150, the cells above the hole, there are big and small, in the middle there is one small interval ...... "This tree's growth rings is not obvious, the fossils cell size is gradual. "Wan Ming Li said, with a microscope, they also found the tree" living "the situation is not good, it was mites Kenshi, the body is full of mites droppings.<br> <br>255 million years ago,http://www.postyourflasher.com,woolrich sito ufficiale, Turpan annual average temperature is around 13 ℃<br> <br>. "Plant is climate change 'thermometer',http://my.5754.cn/home.php?mod=spacecp&ac=blog&blogid=,hogan outlet sito ufficiale, when the paleoclimate, paleoenvironment how, by plants can interpret it," Wang Jun,http://war.kuronowish.com/min/light/light.cgi?gtugg, the Turpan - Hami Basin, paleoclimate, Professor Yang Wan has been studied for more than 10 years, Previously, scientists have for the plants surrounding the lithosphere, soil, suggesting a general situation where the ancient climate, but it has been the lack of botanical evidence.<br> <br>In fact, the plants on the climate, more sensitive to carbon dioxide, rain, temperature high, trees grow relatively fast, petrified wood in the cell will be relatively large; the weather is cold and relatively dry, tree growth will be slower, petrified wood cells will be more compact.<br> <br>By "Steinmann septate pith pine" fossil research, Wan Ming ceremony to restore the 255 million years ago, the climate of Turpan. . "There is not a natural Huoyanshan, 255 million years ago, there is very cool, moist," Wan Ming Li said, at that time, Turpan - Hami basin is about 50 degrees north latitude,http://sportsfan.jpn.org/cgi-kban/sunbbs.cgi?mode=form&no=127&page=1, and the annual average temperature at 12-14 ℃, annual average 900-1240 mm rainfall.<br> <br>And today's climate causes Turpan Basin, Wan Ming ceremony that it might be related to the emergence and Bogda Mountains. Dating back about 250 million years ago, as the Tarim and Junggar Plate - Micro plate collision Turpan,http://store.shopping.yahoo.co.jp/spark-inc/kit-70wu-h3c-10.html, plus Cenozoic plate motion collision, extrusion, forming a Bogda Mountains. "Bogda Mountains,barbour paris, thereby affecting the atmospheric circulation, blocking rain-bearing clouds, causing drought in Turpan Basin today."<br> <br>For this study, Wang Jun, their ultimate goal is to explore the period dating back 300 million years to 250 million years on Earth prosperous sudden extinction of biodiversity reasons. "Steinmann septate pith pine is,http://sportsfan.jpn.org/cgi-kban/sunbbs.cgi?mode=form&no=140&page=1, before the end-Permian mass extinction biological disappear. At that time, 95 percent of the world's marine life and 75 percent of terrestrial organisms in the mysterious disappearance of 'short-term' within."<br> <br>(Original title: 255 million years ago, Turpan not brazier very cool)<br><br>
