A rich stone tool assemblage is described of the Sangoan-type from a potentially semi-primary site, in association with a well-preserved fauna, and in paleo-environmental context. The site appears to be late Middle Pleistocene and contains a high proportion of small to medium-sized mammals (e.g. rodents, monkeys) deposited in low energy conditions. The environment is suggestive of a fringing woodland or riverine forest contained in a subarid climate.  相似文献

"古蜀文明"即"三星堆文明",形成的时间大致在公元前1600年~前1500年之间。三星堆文明形成时期的代表性文明因素主要有3种:一是以三星堆城址城墙为代表的本土文明因素,二是以具有二里头文化特征的文化遗存为代表的中原文明因素,三是以具有齐家文化特征的文化遗存为代表的甘青地区文明因素。后二者是通过早在公元前3500年前后就已经形成的岷江上游地区的文化通道,由陇西南进入成都平原地区,并促使成都平原本土文化发生巨变,产生了三星堆文明,开始了古蜀文明的历程。三星堆文明的形成过程反映了岷江上游地区在古蜀文明的形成这一重大历史事件中,发挥了无可替代的桥梁作用。  相似文献

贵州最早的骨制装饰品出自距今一万二千年至一万五千年前的普定白岩脚洞旧石器时代晚期遗址。装饰品有1件骨笄和1件穿孔兽牙。它们是贵州的首次发现,也体现了贵州远古人类最早的爱美意识。从装饰品本体携带的信息,探索其制作技能,反映出当时人类加工技术的复杂和进步,即对不同用途的装饰品采用不同的加工方式和对同一制品的制作技术逐步改良的处理能力。这既是思维进化指导行为的结果,亦是原始人类迈向更加文明时代的一大进步。  相似文献

Monitoring the degree of asymmetry in different parts of the human body can contribute to population studies, as it may be connected indirectly with the social structure, living conditions, and also with biomechanical stress affecting the person. Analysis of asymmetry may also assess preferential use of the right or left of the body during specific activities. This study is based on the measurements of bones of the upper and lower limbs of skeletons derived from the remarkable medieval cemeteries of Mikulčice‐Kostelisko (78 male, 132 female) and Prušánky (66 male, 69 female) (9th–12th centuries AD), and a series of skeletons representing a recent population from Bohemia (143 male, 157 female). The objective was to assess directional asymmetry (DA), fluctuating asymmetry (FA) and antisymmetry (AS) of the dimensions of the evaluated bones, and to use these data to compare the characteristics of the medieval and recent populations. DA was recorded in most dimensions. In the upper limb, the humerus exhibited the greatest expression of asymmetry, and, with the exception of the clavicle, DA was always more pronounced on the right side. Conversely, DA was less prevalent in the lower limb bones. It was more pronounced on the transverse, sagittal and circumferential dimensions of the diaphyses and epiphyses than on the length, and in most cases it was on the left side. The FA values were very low, and almost negligible in relation to the size. Nevertheless, FA was markedly more frequent on the lower than on the upper limb. In contrast to the medieval population, the recent population had higher FA and DA values. Thus, we propose that people from this medieval population were subjected to lower developmental stress than the recent sample. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

Evidence is accumulating that the hominid cranium found in the Petralona cave in 1960 is associated with cave deposits of middle Pleistocene age. If this is so, the fossil is the most complete middle Pleistocene cranium yet discovered and provides important morphological, metrical and radiographic information on the possible evolutionary transition from Homo erectus to Homo sapiens. The classification of the specimen is discussed and it is suggested that a grade system within Homo spaiens should be erected. The Petralona fossil would be allocated to Homo sapiens grade 1 rather than to Homo erectus or to a subspecies of Homo sapiens.  相似文献

The brissid echinoid Schizobrissus insignis (Duncan &; Sladen, 1883) is described from the Fulra Limestone (late middle Eocene), in Kachchh, India. Formerly assigned to Peripneustes or to Meoma it is shown that the species possesses a complete subanal fasciole throughout ontogeny, a characteristic feature of Schizobrissus. Eocene species of Schizobrissus and Meoma show several morphological similarities, but diverged during the late Paleogene and early Neogene.  相似文献

Over a period of some 100 years it has gradually been accepted that the human skeletal remains found in the late nineteenth century in ancient gravels at Galley Hill, Kent are not those of early man, but are of much more recent date. This conclusion was finally verified by means of relative (N, F) and absolute (14C) dating. Here we present the results of further analysis of the remains from Galley Hill for their uranium content by a method having general application to the relative dating of fossil human and other mammalian bone.  相似文献

Archaeologists often wish to compare observed frequency distributions with expectations generated by a model. We describe a technique of partitioning chisquare which yields information about goodness of fit to a model and about homogeneity among populations simultaneously, and which is often superior to other commonly used methods of evaluating frequency data. The technique is demonstrated with data from the Upper Paleolithic rockshelter Le Flageolet I. The results suggest selective raw material use by the Aurignacian occupants.  相似文献

Lara, M.B. & Aristov, D., August 2016. First records of Geinitziidae (Insecta: Grylloblattida) from the Upper Triassic of Argentina (Mendoza). Alcheringa 41, xxxxxx. ISSN 0311-5518

A new grylloblattid (Permoshurabia argentina sp. nov.: Geinitziidae) is described and illustrated from the Upper Triassic of Argentina. The material represents the first record of this family from Argentina and expands the geographic distribution of this group during the Triassic.

Early Woodland Liverpool (Black Sand variant) pottery decorations consist of belts, rectilinear panels, and/or punctates encircling the vessel. Vertically arranged thematic motifs reflect the structure of the cosmos in its simplest form: Below realm, Earth’s disk, Above realm. This article postulates that the Early Woodland decorative tradition was an enduring symbolic system shared by women making pottery in the upper Midwest. Cosmograms in pottery motifs trace three universal metaphors of the Woodland era belief system: (1) Cooking vessels were feminine spirit-beings; (2) the Woodland culinary vessel shaped like the female form represented her biological destiny as the reproductive vessel for humankind and cooking was a ritual action (“prayer”), a metaphor for the creation of new members of society; (3) the cooking pot was a mandala of cosmograms expressing daily life, ritual practice, and cosmology. These themes carry through subsequent studies on Middle Woodland Havanoid and Late Woodland corded or trailed pottery in an upcoming book.  相似文献
