The last supper of the hominids establishes the times they lived at the sites
Date:7/14/2009

In the French cave of Arago, an international team of scientists has analyzed the dental wear of the fossils of herbivorous animals hunted by Homo heidelbergensis. It is the first time that an analytical method has allowed the establishment of the length of human occupations at archaeological sites. The key is the last food that these hominids consumed.

For many years, the mobility of the groups of hominids and how long they spent in caves or outdoors has been a subject of discussion among scientists. Now, an international team headed by researchers from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) in Tarragona has based its studies on the dental fossils of animals hunted by hominids in order to determine the vegetation in the environment and the way of life of Homo heidelbergensis.

Florent Rivals is the main author and a researcher from the Catalan Institute for Research and Advanced Studies (ICREA), attached to the IPHES in Tarragona. "For the first time, a method has been put forward which allows us to establish the relative length of the human occupations at archaeological sites as, up until now, it was difficult to ascertain the difference between, for example, a single long-term occupation and a succession of shorter seasonal occupations in the same place", he explained to SINC.

In the study, recently published in the Journal of Human Evolution, the researchers analyze the dental wear of the ungulates (herbivorous mammals) caused by microscopic particles of opaline silica in plants. These marks appear when eating takes place and erase the previous ones. This is why they are so useful.

Thanks to the "last supper phenomenon", the scientists have been able to analyze the last food consumed by animals such as the Eurasian wild horse (Equus ferus), the mouflon (Ovis ammon antiqua) and the reindeer (Rangifer tarandus). "This method allows us to conf
