The Sheshan site found in Yishui County。Yishui County is located in the southern foot of Yishan, north of Linyi City, Shandong Province，East adjacent to Yixian，West and Yiyuan County、Mengyin County Border，South and Yinan County Advanced，Bei and Anqiu City、Lingying County borders。Yishui is named after the Yiyi River.，Most of the Yihe River is mostly vast flood accumulation、Plain in front of the mountain，About 150 meters above sea level。Yihe River originated from the southern foot of Lushan, Yiyuan County，Enter Yishui at the southeast of Xiahe Village，Turn to southeast afterwards，Convergence with Nuanyang River into the Batayan Reservoir。The Shan Shan Site found that Yuba Shan Reservoir ’s spillover gate is about 300 meters on the east bank of the river。The site is located in the low mountain hills in the hinterland of Yimeng Mountain，West is one of Yimeng 72 崮 崮 崮 崮 崮 崮，About two kilometers of east, two kilometers, two seats，County Zhidai is East、Xiba Mountain，Bataya Reservoir is named after this。

The landform situation around the Shan Shan site has changed slightly before and after the completion of the reservoir。Before completion of the reservoir，Surrounded by the northwest of the site，Floral Water Calcies flow through the northeast to the southwest of the site。Construction of reservoir flood gates in the early 1960s，2000 Gate West Expansion，Restrication of the flood dungeon immediately adjusted，Opened between the two mountains of the site into a new river channel，Since then, the Yihe River has changed from the west side of the site。During 2020,，Rise of the water level to erode the East Coast ground，To expose a large number of fossils，The site was found。Actually，Previously, there were also many fossil locations and old stone relics in the upstream of the Yihe River。

Take a comprehensive，The relics found in Yishui are concentrated in the old stone era early、Two periods in the evening，Early stone tool collection materials are relatively weak，Including Nanga Cave Site and Xishuiwang Site，Animal fossils unearthed Bet365 app download at the same level infer the relative age，belongs to the late period of the middle update。Late stone instrumental relics are the most important in the place where the house is fine，The typical representative of the venue of the old stone nucleus of the old stone in Shandong region found，For the study of the Yichen River Basin and even the late Stone Age of Shandong, the late Stone Technology、Public migration and other important academic value。other，It also found more than 20 places near the site near the site，Most of them belong to the members of the World Animal Group in Huibeiwa。

It is worth noting that the discovery of the bone fossil of the Beiyuan Ape Human head cover in Yishui County。The early 1980s，The "Yiyuan Ape Man" found in Tumen Town, Yiyuan County is the earliest Shandong people currently discovered，It is also the earliest ancient human beings in the middle and lower reaches of the Yellow River，Occupy an important position in the history of anthropology research in my country。"Yiyuan Ape Man" cave site is 60 kilometers at a straight line distance between the site of the cave site。Including the Sheshan site，It has been found that the old stone artifact site has been listed in the Bubu River or its tributary land or the same landform accumulation，This shows that the ancient human activities of the fourth period of the upper reaches of the Yihe River are very frequent，and last for a long time。

　　Bet365 lotto review

2010，Researchers at the Shandong Provincial Institute of Cultural Relics and Archaeological Research Institute continuously conducted special surveys in the Talent of the Paleolithic Age in the area mainly based on the Yilu River Basin，I found the late Paleolithic Age、Old -Neolithic Times Transitional Site and more than 30 places and locations。But the vast majority of the stone products adopt from the surface，No native form，Unable to carry out annual work。After that，The discovery of the Shan Shan site changed this situation。

August 16, 2020，Due to floods and corrosion of the cultural layer of the flood and erosion of the cultural layer of the landscape of the landscape，After the fossil of the same layer, a rich quartz product。Researchers at the Shandong Provincial Institute of Cultural Relics and Archeology after survey on the spot，Confirm that it is the ruins of the Paleolithic Age。At the end of September，Bet365 app download Approved by the State Administration of Cultural Relics，Extract animal bones and stone products that are eroded by the water flow，Collect annual sample。On the side of the overflowing road due to the place where the site is located，You need to carry out construction environmental assessment，I did not start a substantial excavation that year。After that, the excavation work can be divided into two stages。

The first stage of excavation work started in April 2021，Discover area of ​​55 square meters。The site is divided into two excavation areas of North and South。North District includes 1-8th floor，South District includes 5-14 floors。The height difference at the top of the two districts is 3.5 meters，After connecting it，The entire strata stack nearly 8 meters，14 layers of stone artifacts are unearthed，Clean and unearthed and screen out、Collect more than 5,000 cultural relics。Stone products are very rich，Including hammer、Stone stone core、Dip -shaped stone nucleus and various types of stone chips。Tools can see stone balls、Scraper、Cutting device、Sipper、stone diamonds and jagged device。

The excavation work is combined with the combination of explorers and the ditch，The lower cultural layer of the lower part is based on the basic judgment of the compression and formation of the 4 exploration gaps。It is worth noting that，Tag Global 2 Clean up to the 13th floor，In addition to finding an elephant molar，Also unearthed a spatulator with ancient rhomics tooth tooth，Smooth edge of the shovel head，There are traces of scratch noodles。other，Clean the unearthed 3 elephant mandibular bone and 1 section of the femoral bone，​​and a large number of quartz products and primitive cows、Chi Lu and other fossils。Preliminary annual data indicating the site 1-13 layer accumulation age span is 104,000 to 61,000 years away。

The second stage of work continues from April 2022 to December，From the rescue excavation of 2021 to active excavation，The excavation area is 50 square meters，Clean up to the top of the 14th layer，A total of more than 5,000 pieces of mammalian skeletal fossils and stone products unearthed in the unearthed medium -sized mammalian bone fossils。The animal bone fossils unearthed this time are richer，Except Gu Ling tooth found in 2021、Putting Rhino、Original Cow、Elk、bet365 Play online games Chi Lu、Sheep Wai，Ambassador Mustang was unearthed、Wild pig、Small deer family and small mammals bone fossils。The types of stone products have not changed much，Still hammer、Stone stone core、Dip -shaped stone cores and various types of stone chips and tools，The proportion of scratches and cutters increases，Many pieces of stone hammers were unearthed。

After two years of work，The entire section generally shows four sets of accumulation: the upper part of the 1st to the 6th is the upper pile，Times 70,000 to 60,000 years，Powder sandy clay layer, which is manifested as subtlly and containing weathered shale, gravel，Only stone products without animal fossils were unearthed。7、8 layers for gray powder sand layer that is renovated by strong water flow in place for in place，The 8th layer can be divided into two sub -layers，The lower part of the brown -red clay is revealed，Only visible on the east profile。These two layers are manifested as a gray powder sand layer mainly containing limestone gravel containing different particle size，A large number of cultural relics were unearthed。The accumulation of the 9th to the 11th layer has the nature of the river beach，Each layer can be refined into multiple sub -layers，Powder sand layer with a slight difference in color and granularity sedimentation，Also unearthed the abundant quantity of stone products and animal fossils。The 12th to the 14th layer is the lower cultural layer，Among them, 13th、The earliest age，or 100,000 years ago。Large mammalian fossils mainly based on Guling tooth elephants and rhinoceros are extremely rich，At present, 7 ancient diamond teeth lower jaws and 2 hairy rhinos are found。Rich in the number of stone products。The 14th layer should be the gravel layer (unknown)，The material is a limestone and shale with high grinding circles。The distribution status of the unearthed objects shows that it has the characteristics of human activity surface，That is, ancient humans are made on the gravel surface exposed by the river beach、Daily activities such as dispel animals。Clean the unearthed stone hammer、Avil and other places buried in -site utensil type，Compared with the exposed Shang cultural accumulation，Dedicated proportion increased。Based on the degree of grinding of stone products，The site has been underwritten Bet365 lotto review by the river in the later stage，Only individual stone product debris is stored in the gap between the gravel。

　　Main harvest

More than 10,000 cultural relics have been unearthed since the Sushan site self -discovered，Among them, more than 7,000 stone products，Animal bone angle fossils more than 3,000 pieces，Quantity huge，Covering the type rich。Stone products mainly use quartz as raw materials，Quartet sandstone and vermiculite occupy a small proportion，Types include Hammer、Stone stone core，Dip -shaped stone nucleus and various types of stone chips，Tools can see stone balls、Stone Hammer、Scraper、Cutting device、Sipper、stone diamonds and jagged device。Rich types of animal bone fossils，The currently identified species include ancient diamond teeth、Putting Rhino、Original Cow、Bull、Sheep、Push Mustang、Wild Donkey、Wild pig、Elk、Chi Deer and Small Deer Family。The unearthed animal fossil species is basically consistent with the night update of the Sarahu Su animal group。The Shan Shan site has significant academic value and academic significance，It is mainly manifested in the following four aspects。

First，The richest cultural connotation of the cultural connotation in Shandong。Previously in Rizhao Donggang District、Huangniangliang site and Dazhu Mountain site found in Huangdao District, Qingdao，All are the rare in -site old stone artifacts in Shandong.，But the significance of the Yishui Bao Shan site is more significant。Its main features are more stacked in the strata，Ancient human activities last longer; the number of stone products and animal fossils is more abundant and diverse，and contain animal bone、Corner、Teeth and other tools; existing ancient human activity surfaces，Human behavior that exposes the ruins of fire and disintegrate animals。

Second，One of the few important relics in North China。Compared with the same time relics found in North China in recent years，The unearthed objects of the Shan Shan site are more concentrated、The combination is more complete，filled the blank of archeology in the old stone era in Shandong and northern China。The most important thing is，Animal fossils mainly based on ancient diamond tooth skeletons are the same as a large number of stone tools at multiple layers，It is extremely rare in North China and even the country，For restoration、Study the use of ancient humans in the middle and late period of the world bet365 live casino games to provide extremely important archeological materials for the use of the ruins and the way of livelihood methods of the site。The site of the site is based on quartz products，The rich quartz rock veins produced by the Shanbian Mountains near the Source。The location of the ancient human residence is nearing the river，Also close to the origin of the stone，Show good best selection ability。

Times and Stone Products Features of the Shan Shan Site，Jinggou site in Tonghe Nihewan Basin, Hebei、The cultural connotation of the Banjingzi site and the new temple site is closer。In terms of animal group composition，Qian'an Claw Village site similar to the cultural era、Xuchang Lingjing Site has a lot of commonality。The Animal Group of Claw Village is a typical late update world animal group in North China，The animal species of the Shan Shan site are very similar to the claw village，Animals contained in the animal are more than the latter。

third，It has important academic value for studying international hotspots。At present, the preliminary annual measurement data indicates that the site's accumulation is 100,000 to 60,000 years away from the time.，The age of the cultural layer will be earlier。Therefore，The cultural period where the Shan Shan site is more critical，Geological burial accumulation process is complicated and rich，It provides key new evidence for the appearance and development of modern people in China and East Asia，Answer to the natural environment of the natural environment in the middle and late stages of the night update，The last ice period (70,000 to 115,000 years ago) Origin of East Asian modern people、Migration and other international hot issues have important academic value。Unique geographical location in Shandong area，Obvious biological diversity，In explaining the problem of the spread of the East Asian people, other areas cannot be compared and replaced by other areas。

Fourth，Provides important basis for studying the behavior mode and connotation of modern people。The site's sedimentation environment is a typical river pile of rivers，The dual structure with clear rhythm，Specifically belonging to the Yahe Class II base level。Cultural layer with powder sand retains rich ancient human activity information。The lower bottom gravel layer of the site and the static water sedimentation environment bet365 Play online games of the upper river marshuma is the first active surface used by ancient humans，Ancient humans complete the hunting of large mammals in this area、slaughter、Repeatation and other activities。A rich number of artificial products was found，It reflects planned and forward -looking in ancient humans in survival strategy and behavior activities。Bone makers represented by ivory shovel -shaped bone machines to explore the very important physical information of modern people's behavior mode。

Through the excavation of the Shan Shan site and carry out system investigation and excavation work centered，It will definitely drive the development of the upper reaches of the Yihe River and even the entire Yilu River Basin.，To establish a continuous and complete regional old stone era archaeological culture sequence，Solution to promote major problems in archeology。
