Welcome to theexhibition of the salt well ancient scenes. The main show here is the Orientalsabertoothed elephant found in the Yangzhou salt pit and the fossil of itsdiverse fauna.

Yanjing yancheng islocated in the town of kaojiaojia village in xin tian district, about 30kilometers from the main city. Since the early 30s,archeologists have found fossils of the quaternary mammal species in theregion.

Through the displayof the young Oriental saber-toothed reproductions and molars in the side of thebooth, the fossil is to be felt.

The fossils are theremains of the bodies or the remains of the creatures living in prehistorictimes. So how did they form? Showed that after death, the remains are buried bysediment in a timely manner or trace, as the years went by, the muscle isrotten, the rest of the bone under the action of groundwater, some mineralsseep into the bone gap. Over time, the bones become both hard and heavy, andthe outer structure of the skeleton and the inner shape remains unchanged. Theresearchers found that the death of the animals buried there are usually twokinds of forms, one is: some stumble or being chased by a carnivorous animaland caves in the chasm, die cannot extricate oneself, by running water of clayburied, buried features are: save the animal fossils bone structure, individualcomplete; Another is: after a predator prey on legacy of animal bones, orelderly natural dead animal carcasses, longer exposed on the surface, by eatinganimals and disrupt, bacterial decomposition process, such as the rest of thebone by flash floods rushed to move into the cave and sediment is buriedtogether, its buried features are: a variety of animal bones, weathering,erosion is serious, mixed with a certain grinding roundness of gravel.

The center of theground is restoring a form of the burial of the salt well in the animalkingdom. Audience friends, you can look at what kind of burial form it belongsto?

  Since the ancient times, ancient fossils ofthe area has been the local villagers as traditional Chinese medicine"dragon bone" mining for sale. In the autumn of 1921, the Americanmuseum of natural history central Asian expedition leader Dr Glen order(Granger) to the Yangtze river basin, from the time the British consul inYichang Buddha Lang Smith got near yichang upstream wan Xian municipality foundinformation about the fossil bones. So he inverse jiang and arrive in wanxianmunicipality, in some Chinese pharmacy he discovered the "dragonbone" this taste traditional Chinese medicine (TCM), and relying onexperience, he knew that this ancient mammal fossils. Traced back, large mammalfossils found in uncertainty wan Xian municipality. They go through three timesbetween 1921 and 1926 large-scale excavation, Oriental stegodon collected quitecomplete, such as large tiger, rhinoceros, the giant panda and raccoon hasimportant value of ancient fossils, shipped back to the United States, abundantfossils shocked the world ancient biology, since this batch of fossil remainson display in New York's museum of natural history. In 1953, Carl Herbert etal., say they are "fauna wan Xian municipality" or "uncertaintyfauna".

  The famous founder of vertebratepaleontology in the 1930 s young and quaternary geologist Jia Lanpo had to thisinvestigation. From 1985 to 1986, the institute of vertebrate paleontology andpaleoanthropology, Chinese academy of sciences and Chongqing museum of natureand uncertainty, get a lot of valuable specimens, the skeleton of a giant pandaspecimen of its kind in the world the highest integrity.

   In 2007, 2011, jointly Chongqing wanzhoudistrict museum museum of nature, Chongqing institute of ancient China threegorges museum has a cave of uncertainty big pass disentombs, won three moreintact Oriental stegodon and various associated animal fossils, a total of 5 to12, 9 families. Center exhibition is on display at the above 2007, 2011, theuncertainty of the three east stegodon fossils, below the booth and storefrontdisplay is next to the east of the stegodon limb bones, spine, shoulder blades,skull, incisors and associated animal fossils in this period.

 Buried so abundant fossils, area and theregion special geology, landform, environment and so on are inseparable.Uncertainty due to belong to the typical karst karst landforms, mountain ismainly composed of limestone, overlying yellow clay. Limestone weathered, withthe accumulation of time, will form the underground cave or underground river, largeand small ceiling collapsed, can produce large vertical hole. Ancient times,the lush jungle, valleys, rivers throughout, a typical subtropical rainforestclimate settled here attracted a lot of animals. These animals is a bit notcareful, you may fall into the hole. Limestone and clay quickly above theburied for animals died after effectively save and fossils has provided theadvantageous condition. With the progress of human civilization, science andtechnology, especially since the industrial revolution, the earth's populationincreasing, the need of life resources more and more, excessive exploitation ofnatural resources, scope of human activities is more and more big, the largenumber of forest, grassland, rivers disappear, coupled with the naturalevolution of species, many animals such as dinosaurs have become extinct. Thecurrent uncertainty fauna in the vast majority of members have no identicaldescendants live here.

 Dear audience friends, there is only oneearth, human nature is home to the survival of all life on earth, to curbenvironmental deterioration in the earth's natural, to create the bright futureof human beings and nature in harmony, is the responsibility of each one of us.Let's act together: to protect the environment, the protection and preservationof our home!
