Sophisticated 115,000-Year Old Stone Tools Discovered In China
Marks found on the excavated bone fragments show that humans living in China in the early Late Pleistocene were already familiar with the mechanical properties of bone and knew how to use them to make tools out of carved stone. These humans were neither Neanderthals nor sapiens.
This major find, in which Luc Doyon of UdeM’s Department of Anthropology participated, has just been published in the scientific journal PLOS ONE.
“These artefacts represent the first instance of the use of bone as raw material to modify stone tools found at an East Asian early Late Pleistocene site,”said Doyon. “They’ve been found in the rest of Eurasia, Africa and the Levante, so their discovery in China is an opportunity for us to compare these artifacts on a global scale.

Three types of hammers
The seven bone fragments analyzed by Luc Doyon and his colleagues were excavated between 2005 and 2015 at the Lingjing site in central China’s Henan province. The artifacts were found buried at a depth of roughly 10 metres. At the time, the site was being actively used as a water spring for animals. Prehistoric humans likely used these water supply points for killing and butchering their animal prey.
The bone fragments were dated using optically stimulated luminescence (OSL), a method widely used by geologists for dating the sediment layers in which tools are found.
Doyon explained that the researchers identified three types of bone retouchers, known as soft hammers, that were used to modify stone (or lithic) tools. The first type was weathered limb bone fragments, mainly from cervid metapodials, marginally shaped by retouching and intensively used on a single area. The second type was long limb bone flakes resulting from the dismemberment of large mammals, used for quick retouching or resharpening of stone tools. And the third type was a single specimen of an antler of an axis deer that, close to its tip, shows impact scars produced by percussing various lithic blanks.

More discoveries to come
The analyses that led to the identification of the bone tools were conducted by Doyon and his colleagues Francesco d’Errico (Université de Bordeaux), Li Zhanyang (Shandong University) and Li Hao (Chinese Academy of Sciences), at the Henan Provincial Institute for Cultural Relics and Archaeology.
Doyon participated in the project while working on his doctoral thesis on hunting weapons manufactured from osseous materials by the first Homo sapiens inhabiting Europe between 42,000 and 30,000 years ago. Having earned his PhD in anthropology from Université de Montréal in cotutelle with Université de Bordeaux (PhD in prehistory) in September 2017, Doyon will now pursue a postdoctoral fellowship at Shandong University to conduct further analyses on the bone tools discovered at the Lingjing site.
“We only had access to a small sample, because the initial aim of the project was to study the anthropogenic nature of the modifications present on other bone fragments, and this project is still ongoing,” he said. “The osseous artifacts excavated from this site were exceptionally well-preserved and the systematic analysis of all the bone assemblages during my upcoming postdoctoral research is certain to yield more exciting discoveries.”

Surprise , Surprise ! Yet we find more eveadence someone or some group has been hiding history or changing it ! My guess is the NWO natzi Vatican Esau Edomites ! That’s who the Bible points the figures at ! In trying to understand the Bible with out the aid of someone who is trying to keep me in their ritual understand or ritual control tactics , I find that there were beings or maybe people here since 150,000 years ago . These people as science states came upon earth at this time . They were the White type O blood types that Genesis chapter 1 tells of their creation . Chapter 2 after GOD rests and enjoys HIS work of creation of chapter 1 , He creates a Garden in Eden . The Bible states that HE look to see if there was any among those already on earth to see if they could tend or work HIS garden . But the Bible says HE found none . It is at this time GOD forms Adam and places him in the Garden , later takes one of his ribs to make him a help meet , Eve . This takes place 5778 years ago according to the Hebrews and science backs it up that at this time type A blood type shows up on planet earth . Here is where many people say No there was no other people , Adam and Eve was the first . But to them I ask so who did Cain and Seth marry . They say Adams daughters or their sisters . WRONG !!! Adam was 235 when Seth married and Seth was 105 when he married . There are writing that tell us Adam begged Seth not to marry of the tribes of the earth , Let GOD make you a wife like HE did for me ( Eve ) . But he burn with desire and married . Back to our time table of Seth 105 and Adam 235 . The Bible states that Adam did not have anymore children after Seth until he was 800 years old . So here we can truthfully say No Seth did not marry his sister . And Cain did not marry his sister . Cain married before Seth was born . So who did Cain and Seth marry ? A woman of type O blood type from the tribes of type O blood people . The Bible also hints that there was a time when other beings or people were on earth before it was destroyed durning the fight between lucifer and GOD . In Genesis GOD tells those HE created to go forth and ( replenish ) the earth ! This tells me that once there was others . Now to prove my point and back up the Bible , look up (800 million year old princess found in coal mine ) then click on Tisulsky Princess – Girl in Casket – is at least 800 … You can click on the photo images of the young lady , but I don’t know if it’s the actual girl or just a similarity to help you visualize close to what tge people of the town saw . The body was to my understanding carbon dated to come up with the 800 million year old time dating . But if you read the Russian letter you find she was found to be exactually like modern man kind . But the material of the clothes she had on scientist could not discover what substance on earth matched her clothing material . And there seemed to be a cell phone looking device in the coffin with her . So can we say even back then women were texting , doing selfies or possibly face booking – Ha! Ha! Only ment to be joke or funny ! So don’t bet me up for kidding around . Trying to put puzzle pieces of information together as they are being found we can truely say what really happen in the past does not match our history books they are printing today . What profit is being gained out of changing history ? I do know but GOD pointed these changes out to HIS prophets that the evil group was changing HIS times , seasons and laws ( vatican NWO reptilians ) . And that in the end HE was going to have them totally destroyed from existing as a race of beings .
The Tulinskinsy photos show two types of princesses. So baloney.
Also “replenish” means to “fill”.
