Aitor Ruiz-Redondo is a Senior Lecturer in Prehistory at the University of Zaragoza (Spain) and a British Academy Newton International alumnus. He obtained his PhD in Prehistory and Archaeology at the University of Cantabria (Spain) with a thesis about Palaeolithic graphic behaviour in South-western Europe. He later undertook postdoctoral positions at the Universities of Bordeaux (France), Southampton (UK), and Zaragoza (Spain), where his research has mainly been dedicated to the study of Upper Palaeolithic societies of Eastern Europe. He has led international research projects in Bosnia and Herzegovina, Croatia, Montenegro, Serbia, Spain, and UAE. Since 2020 he is vice-president of the UISPP 'Prehistoric art' world commission. William Davies is Professor of Palaeoanthropology at the University of Southampton (UK), and has developed strong research interests in the later European Palaeolithic (100,000-10,000 years ago) over the last 30 years. His research has focused on integrating palaeoanthropological, palaeoclimatic, and palaeoenvironmental datasets within robust chronological frameworks (Stage 3 Project, 1996-2002; S2AGES project, 2001-2004; EFCHED and RESET programmes, 2004-2013), as well as the characterisation of creativity and innovation in ceramic and other Palaeolithic technologies. He has lectured at the University of Southampton since 2006, and before then held post-doctoral research positions at the universities of Cambridge, Southampton, Oxford, and London.
