When piecing collectively the cultural practices of historic people, conventional archaeologists depend on clues from artifacts comparable to instruments, bones, and pottery. Experimental archaeologists, nonetheless, go a step additional—recreating previous behaviors to expertise how individuals as soon as lived.
That’s exactly what a workforce of researchers lately did to research how Stone Age communities in northeastern Europe extracted animal enamel to supply equipment. Led by Aija Macāne, a visiting scholar within the Division of Cultures on the College of Helsinki, the archaeologists personally examined seven completely different extraction strategies to find out which have been only 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 every day life, particularly cooking practices,” Macāne stated in a college assertion. “This challenges the idea that enamel used for ornaments have been merely scavenged or simply accessible.”
In line with the researchers, animal enamel have been among the many commonest supplies used to make jewellery, equipment, and different private adornments in the course of the Stone Age, particularly within the Northern Hemisphere. Consultants know this due to websites like Zvejnieki, a burial floor in northern Latvia the place hunter-gatherers laid individuals 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 check how historic 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 seemed into the method of extracting enamel and the bodily traces this leaves behind, the researchers word.
To fill that data hole, Macāne and her colleagues obtained their palms soiled—actually. The workforce carried out a collection of experiments to check seven completely different prehistoric strategies for extracting enamel: slicing, percussion (or putting), air drying, soaking, direct warmth, and two cooking methods. They selected these methods based mostly on earlier archaeological and ethnographic analysis. “Whereas different strategies may very well be examined, we argue that these seven are the most definitely given the applied sciences accessible at the moment,” the researchers state of their report.
Over the course of 1 yr, they skilled what it was wish 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 complete, 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 methods proved only. Boiling a mandible in a ceramic pot not solely poached the meat, however brought on tender tissues to detach from the bone, making it straightforward to manually extract the enamel. Inserting total 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 prime 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 private adornments, and funerary rituals.
As for the opposite methods, soaking proved profitable, however didn’t supply further advantages. Slicing or putting the enamel to take away them additionally labored, however that usually trigger injury. The final two strategies—air drying and making use of direct warmth—didn’t yield profitable outcomes.
“Whereas this research centered 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 analyzing methods used for tooth extraction, now we have gained worthwhile insights into human habits and cultural practices in the course of the Stone Age.”
Nonetheless, questions stay. The researchers hope their research will encourage different archaeologists to search for bodily traces of the extraction course of on animal enamel artifacts. Additionally they emphasize the significance of investigating enamel from different species, together with people and canines. Such work, they argue, would shed “a essential gentle on the complexity and significance of those practices.”
