摘要: The skeleton of a young prime adult cave bear, Ursus spelaeus, was found in Chiostraccio Cave (Siena, Tuscany, central Italy), only slightly buried under rock falls. specimen dated yielding conventional age 24,030 ± 100 14C yr BP (29,200–28,550 cal BP), which makes it the latest known representative species Italy. accompanied by remains wolf (Canis lupus), wild boar (Sus scrofa), aurochs (Bos primigenius), red deer (Cervus elaphus), roe (Capreolus capreolus), bat (Vespertinus murinus), and crow (Corvus monedula). site seems confirming that Italian U. spelaeus populations shared risk intrusion. association bear with other animals suggests assemblage is an attritional palimpsest different not originally associated life. bears were probably more vegetarian than brown possibly became extinct when plant productivity dropped at onset MIS 2. Central southern Italy may have offered isolated sheltered refugia for bears.
