Cenomanian vertebrate assemblages from southwestern France: a new insight into the European mid-Cretaceous continental fauna

Cenomanian paralic deposits of Charentes (southwestern France) have yielded abundant vertebrate microremains, including rather diversified continental taxa (e.g., frogs, turtles, crocodilians, dinosaurs, pterosaurs, lizards, and mammals). In this short report, the succession of faunal assemblages observed is briefly described in relation to palaeoenvironmental change resulting from the Cenomanian-early Turonian transgressive episode. Continental forms occur commonly in estuarine and shallow marine rocks of the lower part of the Cenomanian stage, but seem to be lacking in younger strata deposited in more open marine settings. Among an unexpected biodiversity, several non-marine groups (e.g., ziphodont crocodilians, carcharodontosaurid and troodontid dinosaurs, marsupial-like mammals) are recorded for the first time in the lower Upper Cretaceous of Europe, thus providing new palaeobiogeographical indications for this poorly documented part of the world.     

吉林省大布苏国家重点化石产地的猛犸象-披毛犀动物群

猛犸象-披毛犀动物群是晚更新世时期北半球最具代表性的典型哺乳动物群,该动物群的化石在中国东北地区广泛分布,其演化、发展乃至灭绝与古人类文明的发展有密切的关系。综述猛犸象-披毛犀动物群的概况,从动物组合、古地理分布、古生态环境等方面介绍了该生物群之全貌。以吉林省大布苏国家重点化石产地为例,对该产地出土的猛犸象-披毛犀动物群化石标本进行了最新的统计(分属6目13科21属23种),对其化石组合特征进行了分析,并对在东北地区深入开展该动物群研究的意义进行了探讨。     

长白山玄武岩台地土壤动物多样性及其生态地理分布

于2014年春、夏和秋季对长白山玄武岩台地原始针阔混交林、次生针阔混交林、次生落叶阔叶林及耕地土壤动物进行研究。结果表明：大型土壤动物的多样性,春季次生针阔混交林为最高,夏季和秋季原始针阔混交林为最高,耕地在3个季节均为最低;中小型土壤动物的多样性,春、秋两季原始针阔混交林为最高,夏季次生针阔混交林为最高,耕地在3个季节仍为最低。根据一维方差分析可知春、夏、秋3个季节原始针阔混交林、次生针阔混交林和次生落叶阔叶林土壤动物类群和平均密度均显著高于耕地（p<0.05）;而各生境土壤动物的类群和平均密度季节变化差异不显著（p>0.05）。各生境土壤动物的多样性呈现出随土层深度的增加而降低的趋势。土壤温度、速效P、有机质和土壤湿度的变化是影响长白山玄武岩台地土壤动物多样性地理分布的主要因子。     

Quaternary fossil fauna from the Luangwa Valley,Zambia

This paper describes a large collection of Quaternary fossil fauna from the Luangwa Rift Valley, Zambia. Stone Age artefacts have been recovered from stratified fluvial contexts, but no in situ fossil faunas have yet been recovered. We report on 500 fossil specimens collected from the surface of point bars exposed seasonally along the banks of the main Luangwa River channel. We used non‐destructive X‐ray fluorescence analysis of the fossils' chemical signatures to determine whether they derive from one or many primary contexts, and the relationship between chemical signature and state of preservation. Specimens are identified to taxon (genus) to reconstruct palaeoenvironments and biochronology. A relatively wide range of taxa is identified, including a fossil hominin talus, described here. None of the fossils is positively attributable to extinct species, except a femur of an extinct Theropithecus reported in 2003. Although no additional extinct taxa were identified, some of the remains were attributable to genera that are not currently found in this region. The results suggest that most of the assemblage derives from sediments which are Middle Pleistocene or later, and that past environments in the Luangwa Valley may have differed from the habitat availability found today.     

The biota of Romanian saline lakes on rock salt bodies: A review

An inventory of the aquatic and circum-lacustrine flora and aquatic fauna of 23 karst- and anthroposaline lakes formed on Miocene rock salt bodies in Romania was undertaken. Simultaneous field determinations of water and sediment pH, total dissolved solids, Secchi transparency and lake maximum depth were also made. Environmental conditions for phytoplankton, microphytobenthos, macrophyte and cormophyte species were defined. Relations between the numbers of plankton, microbenthos, macrophyte and cormophyte species differentiated pelogenous (usually, therapeutic) and non-pelogenous lakes. High densities and occurrence frequencies characterized the most representative species. For three of these species, Amphora veneta, Artemia sp. and Potamogeton pectinatus, ecological conditions were noted. In the circum-lacustrine vegetation, glycophytes were more important than halophytes.

对陕西蓝田几个哺乳动物群的层位及时代的新认识

过去认为涝池河—阳郭动物群的时代相当或稍晚于泥河湾动物群,早于公王岭动物群,厚镇涝池河动物群的时代与公王岭动物群的一致。但各动物群的层位及在动物群演化上所处的位置表明涝池河—阳郭动物群的时代应与公王岭动物群的一致,比泥河湾动物群的晚,而厚镇涝池河动物群的时代应与陈家窝动物群的相当。重新厘定了公王岭期与陈家窝期的涵义,认为蓝田黄土地层中、早更新统的界线应划在Ｓ８与Ｌ９交界处。
