Throughout history, man has left behind various clues to his presence and activities, such as carved stone tools. However, does the absence of these tools mean that man was not present in a territory? The discovery of traces of butchery on mammoths in America indicates that our species was present on this continent as early as 37,000 years ago. You may also be interested
[EN VIDÉO] Finally the mystery of the fourth mammoth is clarified In 150 years, only four mammoths have been discovered in France. Banished in Changis-sur-Marne, this specimen is particularly well preserved. This amazing documentary by Inrap (National Institute of Preventive Archaeological Research) talks about a thorough investigation to understand what happened to this animal. The presence of the human species in the New Continent is generally estimated by archaeologists through the identification of remains of the lithic industry. The oldest traces of an elaborate lithic industry in Europe date back to the Upper Paleolithic revolution, about 45,000 years ago. Then it spread to Siberia as well as Asia, to finally be brought to America about 16,000 years ago. However, the date of introduction of these tools to America is widely associated by archaeologists with the arrival of the human species to this continent. This last point, however, has just been questioned by an international research team, which published an article in the journal Frontiers in Ecology and Evolution, the authors of this study describe their discovery of mammoth remains at the level of the population. of Hartley, located on the Colorado Plateau in northern New Mexico. The remains consist, in particular, of a tusk – which was already exposed at the site -, ribs, a molar, vertebrae and a mammoth jaw belonging to an adult female as well as her young. Butchery remains of Clovis d ‘obsidian, which are Artificial projectiles were also found at the site. The Hartley site had previously been identified as a likely butchery site, but the authors indicate that the mammoth remains may predate the projectiles. The mammoth remains are disarticulated and piled to a depth of one meter, and the skull bones and tusks are placed on top of the pile. The analysis of the collagen contained in one of the bones of mammoth reveals that the specimen dates back to around 37,000 years ago. The skull of the adult female shows signs of fractures caused by repeated impacts, characteristic of gestures made in order to break the bone to access the brain and other soft tissues of the skull. In addition, the diameter of the perforations in several bones suggests that these were not caused by carnivorous canines but by tools. Short, wide, parallel marks on a rib are otherwise consistent with the use of coarse butchering tools and suggest that the ribs were systematically separated from the mammoth backbone. The disarticulation of the vertebrae as well as their perforation was also probably carried out in order to extract the fat more easily. The authors finally indicate that the presence of traces of butchery and human activity in America 37,000 years ago is in agreement with the hypothesis that two different human groups colonized the Americas: one before the last glacial maximum (-31,000 years) and the other about 16,000 years ago.
