Also found in: Dictionary, Thesaurus, Legal, Idioms.
a settlement in Belgium, in Namur Province, near which the fragments of two Neanderthal skeletons were found in a cave in 1886 during archaeological excavations conducted by the Belgian scientists M. Lohest and M. de Puydt. Also found were the bones of a mammoth, a woolly rhinoceros, a cave hyena, and other animals of the Würm, as well as Mousterian stone weapons. On the basis of these finds it was possible for the first time to establish the period during which a specific type of Neanderthal man existed. The people from the Spy cave were characterized by a large brain (1,500–1,600 cc). Anthropologically, they were late Neanderthal men who lived in Western Europe 40,000–50,000 years ago.
