bet365 offer newspaper’s comprehensive foreign media reports July 11，American Life bet365 offer Network reported，Researchers make important discovery in jewelry of Stone Age humans。

About 100 years ago，Archaeologists have unearthed an 8,200-year-old Stone Age human cemetery in northwestern Russia，A large number of ornaments made of bones and animal teeth were discovered。Recent，To find out what animal the bones came from，Researchers reanalyze these bone ornaments，Surprised to find that some accessories are not made from animal bones，But made of bet365 offer。

Director of the research project、Introduced by Kristiina Mannermaa, an anthropologist at the University of Helsinki, Finland，In Youxiong、Among ornaments made from moose and beaver teeth，Mixed with grooved bet365 offer。Among them，At least two fragments come from the same person’s femur。

But for those who made decorations at that time，bet365 offer appear to be indistinguishable from other decorations。Mannama said，The maker chopped the bet365 offer into pieces quickly，Simply carve a groove in the bottom to wrap the rope around。The size and shape of these bet365 offer，Similar to the teeth of animals near where they were found。This may indicate that bet365 offer could be used to replace animal teeth under certain circumstances。

Amy Gray Jones, senior lecturer at the University of Chester, UK, commented，This apparent fungibility does not mean that people at that time did not respect bet365 offer。Stone Age，Ancient Europeans valued bone ornaments and tools，Special treatment will also be done after use。They believe that both animal and bet365 offer are very important，Nowadays, Western culture generally believes that animal bones are worthless。New method for molecular analysis of collagen used in this study，May help researchers find more bet365 offer among the bone fragments that have been excavated。

Some scholars believe，Compare the DNA of the bet365 offer in the jewelry with the more complete human skeletons unearthed from the same cemetery，Analyze the blood relationship between them，will be a new research direction。But，Mannama thinks，This kind of research requires the destruction of a lot of bones，So it is not yet a research direction that researchers are committed to exploring。
