Analysing criteria of formation in multi-stratified karst deposits: the observation of surfaces in Late Pleistocene faunal bones from Mora Cavorso cave (Latium, Central Italy)

Abstract

ABSTRACT Mora Cavorso cave is mostly known for preserving one of the largest human burials of early Neolithic in Central Italy, but it holds archaeological and palaeontological finds ranging from Late Pleistocene to historical times. The observation of faunal bone surfaces from Late Pleistocene layers has been carried out mainly to verify the human contribution to the formation of the bone accumulations. The assemblages are made up of about 3750 finds, 48% of which taxonomically identified, while 31% of the total show traces of surface alterations. Layer 8, the deeper and partially excavated, shows few traces on 28 finds with a dark patina. For Layer 7, boluses by birds of prey, traces of digestion and gnawing by small carnivores show the main agents of the formation of the bone accumulation. For Layer 6, just a small percentage of finds shows traces referrable mostly to small carnivores, with a few traces referrable to rodents. For Layer 5, gnawing of small carnivores was observed, however the occurrence of burnt bones and cut traces confirmed the hypothesis, based on the discovery of lithic artefacts, that the oldest human attendance in the cave is here attested and dates to Epigravettian period.
