Further research at the Oldowan site of Ain Hanech,North-eastern Algeria

Further investigations were carried out at Ain Hanech, Algeria in 1998 and 1999 to explore its potential for investigating early hominid behavioral patterns and adaptation. Research concentrated on the stratigraphy and dating, identifying new archaeological deposits, and excavating the Ain Hanech and El-Kherba localities. To enhance the chronological control within a biostratigraphic framework, the Ain Boucherit fossil-bearing stratum, yielding a Plio-Pleistocene fauna, is correlated with the regional stratigraphy. In the stratigraphic sequence, the Ain Boucherit stratum, located 13m below the Ain Hanech Oldowan occurrences, is found in Unit Q of the Ain Hanech Formation. Unit Q shows a paleomagnetically reversed polarity, which may be correlated with an age earlier than the Olduvai normal subchron (1.95-1.77Ma). Based on test trenches and stratigraphic analyses, additional Oldowan deposits A, B, and C are identified at Ain Hanech. All three deposits and the El-Kherba site contain Mode I technology artefacts associated with an Early Pleistocene fauna. El-Kherba is stratigraphically equivalent to Ain Hanech. These two archaeological sites are estimated to be dated to about 1.8Ma.     

泥河湾盆地南山根地点发掘简报

南山根地点位于河北省张家口市阳原县大田洼乡岑家湾村西南,考古文化层埋藏于泥河湾湖相层中,地质年代为早更新世。2017年5～7月,河北师范大学考古队对该地点进行了抢救性发掘,在面积为22 m²的范围内共出土编号遗物519件,主要为石制品,出土化石17件。石制品类型包括石核、石片、断块、碎屑、石器等。石制品原料可能为就地取材,取自附近基岩及河滩砾石;剥片方法主要为锤击法;石制品整体形制较小,属于石片石器工业;石制品类型以石片、断块和碎屑居多;共发现25个拼合组,包括57件可拼合石制品,应为原地埋藏。通过与邻近的岑家湾遗址地层对比,南山根地点文化层与岑家湾文化层处于同一自然堆积层内,但较岑家湾遗址文化层稍高,据此推断其年代可能接近并略晚于岑家湾遗址(1.1 MaBP)。     

泥河湾盆地半山早更新世旧石器遗址初探

半山旧石器遗直位于河北省张家口市阳原县泥河湾盆地东端,埋藏在泥河湾层里。它与工不谷蛇早更新世旧石器遗址以一条正断层相隔。分别在断层的上盘和下盘。半山遗址的位置比东谷索遗址低７０余米,但根据野外观察,二者的地层层位大致相当。半山遗址发掘近２平方米,获得９５件石制品和一些动物化石。初步分析,半山的石制品和东谷索的非常相似,它们应该属于同时期的产物。     

甘肃西部和中部旧石器考古的新发现及其展望

近年在甘肃西部马鬃山区的霍勒扎德盖发现了石叶,在甘肃中部的东乡族自治县发现了王家遗址等旧石器地点。这对推进中国西部旧石器考古,探索我国旧石器时代向新石器时代的过渡,开辟了前景。

消息与动态

1989年2月,该县农民在西牛角峪村采石中,发现少量的动物化石。它们埋藏于石灰岩裂隙的红色粘土中,经中国科学院古脊椎动物与古人类研究所研究人员鉴定为哺乳动物化石的肢     

阳原石核的动态类型学研究及其工艺思想分析

本文从动态类型学角度把阳原石核的工艺程序划分为四道工序和两个亚类型,论证了这种石核发生形态变化的机制。在工艺特征上,阳原石核与日本北海道的(山上下)下型细石核相当,从而证明两地在旧石器时代晚期曾有共同的工艺思想。     

Relationships of microsporidian genera, with emphasis on the polysporous genera, revealed by sequences of the largest subunit of RNA polymerase II (RPB1)

Molecular data have proved useful as an alternative to morphological data in showing the relationships of genera within the phylum Microsporidia, but until now have been available only for ribosomal genes. In previous studies protein-coding genes of microsporidia have been used only to assess their position in the evolution of eukaryotes. For the first time we report on the use of a protein-coding gene, the A-G region of the largest subunit of RNA polymerase II (RPB1) from 14 mainly polysporous species, to generate an alternative phylogeny for microsporidia. Using the amino acid sequences, the genera and species fell into the same main groupings as had been obtained with 16S rDNA sequences, but the RPB1 data provided better resolution within these groups. The results supported the pairings of Trachipleistophora hominis with Vavraia culicis and Pleistophora hippoglossoideos with Pleistophora typicalis. They also confirmed that the genus Pleistophora is not monophyletic and that it will be necessary to transfer Pleistophora ovariae and Pleistophora mirandellae into one or more other genera, as has already been effected for Pleistophora anguillarum.

广西百色田东坡西岭旧石器时代遗址发掘简报

坡西岭遗址发掘共出土 2 4 4件石制品 ,其中石器 4 6件 ,类型分为砍砸器、手镐、刮削器 3种 ,制作简单、粗糙 ,极少经过细致加工。这与百色盆地其它旧石器时代遗址所发现的石器具有相似的特征。其年代为旧石器时代早期。
