The origin of such assemblages is generally poorly known. ability to create small fish bone accumulations restricted a number predators (including raptors, carnivores humans). In order recognize the agents responsible for these concentrations sites, we have investigated taphonomy from otter spraints determine potential role Eurasian otter, Lutra lutra, formation fossil as piscivorous mammal.
