确定早期人类扩散到亚洲的时间是人类演化研究的中心课题之一。在华北泥河湾盆地马圈沟湖相沉积剖面发掘出四层无可争议的石器层。本项研究的磁性地层学结果表明，这四层石器层的年龄介于Olduvai极性亚时和Cobb Mountain事件之间的近34万年时间间隔内。层位最低的旧石器的年龄约1．66Myr，代表了东亚地区利用石器加工动物遗骨最古老的记录。

在人类演化研究中，不同地区早期人类及石器技术的年代问题一直是争论的焦点。对华北泥河湾翁地的小长梁和洞沟这两个平行的湖相沉积剖面作了洋细的磁性地层学研究，为20多年前在这里发现的旧石器进行了精确定年。古地磁结果表明，小长梁行器层位于奥杜韦和哈拉米洛两个正极性亚时之间的负极性带内。假定这一负极性带形成时间段内的沉积速率恒定，那么小长梁石器层的形成年龄大约是距今1．36Myr。这一结果是东亚高纬度地区（40°N）古人类活动的最早证据。

In an effort to study the systematic affinities and species- level phylogenetic relationships of the enigmatic anurans vadably assigned to the genera Ingerana or Limnonectes （family Dicroglossidae）, we collected new molecular sequence data for five species including four Himalayan taxa, Limnonectes xizangensis, Lim. medogensis, Lim. alpine, Ingerana borealis and one southeast Asian species, I. tasanae, and analyzed these together with data from previous studies involving other ostensibly related taxa. Our surprising results demonstrate unequivocally that Lim. xizangensis, Lim. medogensis and Lira. alpine form a strongly supported clade, the sister-group of the family Australasian forest frog family Ceratobatrachidae. This discovery requires an expansion of the definition of Ceratobatrachidae and represents the first record of this family in China. These three species are distinguished from the species of Ingerana and Limnonectes by the：（1） absence of interdigital webbing of the foot, （2） absence of terminal discs on fingers and toes, （3） absence of circumarginal grooves on the fingers and toes, and （4） absence of tarsal folds. Given their phylogenetic and morphological distinctiveness, we assign them to the oldest available generic name for this clade, Liurana Dubois 1987, and transfer Liurana from Dicroglossidae to the family Ceratobatrachidae. In contrast, Ingerana tasanae was found to be clustered with strong support with the recently described genus Alcalus （Ceratobatrachidae）, a small clade of otherwise Sundaic species; this constitutes a new record of the family Ceratobatrachidae for Myanmar and Thailand. Finally, Ingerana borealis clustered with the ＂true＂ Ingerana （family Dicroglossidae）, for which the type species is L tenasserimensis.

近半个世纪以来,古生物学涉及越来越复杂的现象与过程,难以用传统的经验科学方法来解决。伴随着相关研究引入日益增多的定量分析,古生物学逐渐成为一门可定量分析的科学。作为最早的古生物学专用的免费统计软件包,PAST功能全面、易于使用,并在过去十几年中发展迅速,目前已在相关软件中占据重要地位。本文在简单介绍该软件基本操作方法的基础上,结合古生物学应用案例,解读最常用到的几类"常规统计分析"与"多元统计分析"的使用;同时,针对古生物学相关领域中的"多样性、丰度及居群结构","形态学"和"生物地层学"问题,给出具体分析实例。在相关案例的分析介绍中,详细梳理用PAST实现这些分析的具体步骤,因而具有较好的实用参考价值。受篇幅所限,文章对软件中其他不常用但相对重要的9个模块只进行简要介绍,以供读者在偶尔涉及该类分析时参考。PAST软件不仅功能强大,而且能够针对古生物学及地层学浮现出来的最新前沿问题不断进行调整、更新,值得在古生物学界推广使用。
