关于人类扩散和随后巨型动物灭绝的全球现象的辩论仍在继续。在东白令加，物种年表只是一般建立，并没有提供足够的信息来比较晚更新世人类殖民和气候变化。为了建立一个准确的年表，这些物种，948放射性碳日期与猛犸象，马，野牛，和考古职业的汇编和评级的可靠性，通过标准化的方法。结果表明，8.7%的放射性碳年代是可靠的，85.4%是中等可靠的，7.3%是不可靠的。使用精细的物种年表可以显着影响放射性碳年代频率和古人口研究的解释。
Debate continues on the global phenomenon of human dispersal and subsequent megafauna extinc tions. In Eastern Beringia, species chronologies are only generally established and do not provide enough information for comparisons to Late Pleistocene human colonization and climate change. To establish an accurate chronology for these species, 948 radiocarbon dates associated with Mammuthus, Equus, Bison, and archaeological occupations were compiled and rated for reliability through a stan dardized method. The results indicate that 8.7% of the radiocarbon dates were reliable, 85.4% were moderately reliable, and 7.3% were unreliable. Using refined species chronologies can significantly influence interpretations of radiocarbon date frequencies and paleodemographic studies.
