Denisova Cave in the Altai Mountains of Siberia, Russia is the type locality of the Denisovans. It contains stratified deposits that preserve skeletal and genetic evidence of hominins, artefacts made from stone and other materials, and a range of animal and plant remains. Hominin remains recovered include Denisovans, Neanderthals, and a first-generation offspring of a Neanderthal mother and a Denisovan father, which suggests that Denisova Cave was a contact zone between these archaic hominins [1][2][3][4][5][6][7].
