英文摘要: The extirpation of spotted hyaena, Crocuta crocuta, in northern Eurasia can be seen as part of the late Quaternary megafaunal extinction event. The radiocarbon record for this species is less substantial than for other megafaunal species, but with the addition of new dates we have significantly increased the tally to approximately 100 reliable direct dates. These suggest extirpation at ca40ka (calendar years) in Central Europe and Russia, and ca31ka in north-west and southern Europe, so that the species was probably restricted to the Mediterranean and the Atlantic seaboard after 40ka. Previous records suggesting Lateglacial or even Holocene survival (especially in eastern Asia) are not substantiated. The current estimate of 31ka for extirpation of the spotted hyaena in northern Eurasia is close to the estimated extinction date of cave bear (Ursus spelaeus), suggesting a possible common cause. Factors likely to have impacted the spotted hyaena include, in particular, physiological cold intolerance in the face of deteriorating climate, as well as reduction of prey abundance driven by depressed vegetational productivity, and increased competition for food or space with lions, bears and people, possibly exacerbated by the arrival of modern humans. © 2013 Elsevier Ltd.
