摘要

摘要本文对波兰南部Perspektywiczna洞穴中与洞鬣狗(Crocuta Crocuta)有关的更新世沉积进行了研究。我们使用遗传和稳定同位素分析支持的鬣狗化石的直接放射性碳定年来推断该种群的古生物学。19具鬣狗遗骸的放射性碳定年表明，该地区在MIS 3早期(约50-34 kcal BP)长期居住。在我们的测年数据中，最年轻的是34,355-33,725 cal BP (1σ，同一标本的两个测年数据的组合)，表明喀尔巴阡山脉以北的洞穴鬣狗最晚出现。除了这段漫长的占领时期，Perspektywiczna洞穴鬣狗在生态上保持稳定，但它们的遗传结构发生了变化。有两个mtDNA单倍群存在，一个是其他晚更新世欧洲人群的典型，另一个是迄今为止只在最近的非洲人群中发现的。

NEW INSIGHTS INTO LATE PLEISTOCENE CAVE HYENA CHRONOLOGY AND POPULATION HISTORY—THE CASE OF PERSPEKTYWICZNA CAVE, POLAND

ABSTRACT The paper focuses on the Pleistocene deposits in Perspektywiczna Cave, southern Poland, related to cave hyena (Crocuta crocuta). We used direct radiocarbon dating of hyena fossils supported by genetic and stable isotope analyses to infer the paleobiology of this population. Radiocarbon dating of 19 hyena remains suggests long inhabitation of the region during early MIS 3, around 50–34 ky cal BP. The youngest among our dates, 34,355–33,725 cal BP (1σ, combined of two dates for the same specimen) points out the latest appearance of a cave hyena north to Carpathians. Beside this long period of occupation, the Perspektywiczna Cave hyenas stayed ecologically stable, but their genetic structure changed. Two mtDNA haplogroups were present, one typical for other Late Pleistocene European populations and the other one known so far only from recent African populations.

期刊介绍： Radiocarbon serves as the leading international journal for technical and interpretive articles, date lists, and advancements in 14C and other radioisotopes relevant to archaeological, geophysical, oceanographic, and related dating methods. Established in 1959, it has published numerous seminal works and hosts the triennial International Radiocarbon Conference proceedings. The journal also features occasional special issues. Submissions encompass regular articles such as research reports, technical descriptions, and date lists, along with comments, letters to the editor, book reviews, and laboratory lists.
