When piecing collectively the cultural practices of historical people, conventional archaeologists depend on clues from artifacts akin to instruments, bones, and pottery. Experimental archaeologists, nonetheless, go a step additional—recreating previous behaviors to expertise how folks as soon as lived.
That’s exactly what a crew of researchers just lately did to research how Stone Age communities in northeastern Europe extracted animal enamel to provide equipment. Led by Aija Macāne, a visiting scholar within the Division of Cultures on the College of Helsinki, the archaeologists personally examined seven totally different extraction strategies to find out which have been best and environment friendly. Their findings, revealed June 20 within the journal Archaeological and Anthropological Sciences, supply new insights into the lives of prehistoric hunter-gatherers.
“Our experiments present that tooth extraction was a deliberate, time-sensitive course of embedded in each day life, particularly cooking practices,” Macāne said in a college assertion. “This challenges the idea that enamel used for ornaments have been merely scavenged or simply accessible.”
In keeping with the researchers, animal enamel have been among the many most typical supplies used to make jewellery, equipment, and different private adornments through the Stone Age, particularly within the Northern Hemisphere. Specialists know this because of websites like Zvejnieki, a burial floor in northern Latvia the place hunter-gatherers laid folks to relaxation for about 5 millennia—from 7,500 to 2,600 BCE. Greater than 2,000 animal enamel have been excavated from the graves at Zvejnieki, making it a major location to review how historical people interacted with these supplies.
Archaeologists have extensively studied animal tooth pendants from this website, investigating which species they got here from, how they have been used, the place they have been positioned inside graves, and the way they have been made. Far fewer research, nonetheless, have appeared into the method of extracting enamel and the bodily traces this leaves behind, the researchers be aware.
To fill that data hole, Macāne and her colleagues received their palms soiled—actually. The crew carried out a sequence of experiments to check seven totally different prehistoric strategies for extracting enamel: reducing, percussion (or hanging), air drying, soaking, direct warmth, and two cooking strategies. They selected these strategies primarily based on earlier archaeological and ethnographic analysis. “Whereas different strategies may very well be examined, we argue that these seven are the most certainly given the applied sciences accessible right now,” the researchers state of their report.
Over the course of 1 yr, they skilled what it was prefer to be Stone Age people in want of some toothy bling. The researchers performed their experiments on the Īdeņa Experimental Centre in jap Latvia, which allowed them to supply the required uncooked supplies from licensed native hunters. In whole, they used seven skulls or mandibles from Eurasian elk, two from wild boar, and two from roe deer.
Of all of the strategies they examined, the 2 cooking strategies proved best. Boiling a mandible in a ceramic pot not solely poached the meat, however prompted gentle tissues to detach from the bone, making it straightforward to manually extract the enamel. Putting complete skulls inside an earth oven—a dug-out pit used to lure warmth and, on this case, steam meals—had the identical impact.
Each strategies allowed for top extraction charges with out damaging the enamel, with the added bonus of constructing a meal and rendering the remainder of the bones appropriate for tool-making. These findings recommend that tooth extraction could have been built-in into broader cultural practices, merging meals preparation, the making of non-public adornments, and funerary rituals.
As for the opposite strategies, soaking proved profitable, however didn’t supply further advantages. Chopping or hanging the enamel to take away them additionally labored, however that always trigger injury. The final two strategies—air drying and making use of direct warmth—didn’t yield profitable outcomes.
“Whereas this examine targeted principally on the tooth pendant assemblage from the Zvejnieki cemetery, our outcomes have broader implications for understanding tooth extraction and pendant manufacturing throughout prehistory,” the researchers state. “By inspecting strategies used for tooth extraction, we have now gained useful insights into human conduct and cultural practices through the Stone Age.”
Nonetheless, questions stay. The researchers hope their examine will encourage different archaeologists to search for bodily traces of the extraction course of on animal enamel artifacts. In addition they emphasize the significance of investigating enamel from different species, together with people and canine. Such work, they argue, would shed “a crucial gentle on the complexity and significance of those practices.”
