Man of Tourville-la-Rivière: discovery of a pre arms … – Linformatique.org

A team of scientists from the National Institute of Preventive Archaeological and CNRS announced the discovery of the remains of an old pre-Neanderthal some 200 000 years ago, along the Seine, 15 km upstream of Rouen.

This Thursday, October 9, a team of scientists from the National Institute for Preventive Archaeological and CNRS announced the discovery of the remains of the man of Tourville-la-Rivière. It is the discovery of the three long bones (humerus, radius and ulna) on the left arm of an adult individual, gender still undetermined back some 200,000 years.

Updated the Seine, 15 km upstream of Rouen, these three bones are discovered “major” says Jean-Philippe Faivre, researcher at CNRS and first author of the article published the same day in the journal PLoS One.

With this discovery, it will now be possible to advance the understanding of the dynamics of the population of Neanderthals, their appearance, there are 450,000 years, their disappearance, there are about 30 000 years.

Discovered during a research survey conducted in 2010, it took four years for scientists to make some assumptions. Man of Tourville-la-Rivière is for example not dead on the site, but arrived in the river before being quickly covered by alluvium of the river, which protected him. Without knowing whether the hand was still attached to the arm, scientists also believe that the arm was likely separated from the rest of the body.

The examinations made it possible to date the age of the man Tourville -la-River about 200 000 years while the anatomical study to find the unique features of the Neanderthal lineage. With imaging and topographic reconstruction techniques, they discovered a bone relief 4cm previously unknown to the Neanderthal. Common abnormality among baseball players, this singularity could be “the result of repetitive motion arm extension with distance from the rest of the body,” says Jean-Philippe Faivre, author of the article, “especially as the arm had undergone at least one ligament tear. “

It should also be noted that the site of Tourville-la-Rivière is known since the previous two campaigns had demonstrated a wide variety of animals, carnivores ( bears, wolves), large herbivores (aurochs, horses, deer, deer) and small mammals (cats, rabbits, beavers), as well as an important site of flint
