Footprints indicate human presence in Spain in Middle Pleistocene, 200,000 years earlier than previously thought

Researcher and GRS Radioisotopes technician Jorge Rivera, from the University of Seville, has participated in an incredible discovery that is unique in Europe. After applying an optically-stimulated luminescence technique at the Center for Research, Technology and Innovation laboratories at the University of Seville (CITIUS) and at CENIEH to hominin footprints found at Matalascañas in 2020, Rivera helped to determine that the footprints are in fact 200,000 years older than previously suspected.
