Behavior of wild capuchin monkeys can be identified by marks left on their tools

A group of researchers including Tiago Falótico, a Brazilian primatologist at the University of São Paulo's School of Arts, Sciences and Humanities (EACH-USP), archeologists at Spain's Catalan Institute of Human Paleoecology and Social Evolution (IPHES) and University College London in the UK, and an anthropologist at the Max Planck Institute for Evolutionary Anthropology in Germany, have published an article in the Journal of Archeological Science: Reports describing an analysis of stone tools used by bearded capuchin monkeys (Sapajus libidinosus) that inhabit Serra da Capivara National Park in Piauí State, Brazil. It is the first systematic study to characterize the tools used by capuchin monkeys living in the wild.
