The use shells of molluscsas money is well known in world history. This precedent ended only in the last century. But, the beginning of such use is lost in the depths of the Paleolithic. Reliably established facts of the most remote from modern times, the use of shells as money is known in China (3500 years ago). The possibility of using mollusk shells as money is considered in the abstract on the example of the multi-layered Paleolithic site of Kostenki in the Voronezh region. This Paleolithic site is one of the most studied in Russia. Note at once that there is no direct evidence of the use of shells as money, but the very way of life of Paleolithic man in Kostenki and some features of the structure of mollusk shells, their species identification indicate a high probability of such use.
