An international consortium of paleontologists, geologists and biologists describes the discovery of fossil assemblages spanning the last 130,000 years beneath the Ariane 6 rocket launch site in Kourou, French Guiana. This consortium, coordinated by scientists from the Institute of Evolutionary Science of Montpellier (University of Montpellier/CNRS/IRD) and the University of Guyana/Géosciences Montpellier, involves Frédéric Quillévéré from the Laboratory of Geology  of Lyon: Earth, Planets, Environment (LGL-TPE, CNRS/Lyon 1 University/ENS de Lyon/Jean Monnet University).

These works are published in the Proceedings of the National Academy of Sciences of the USA (PNAS).
