云南保山地区二叠纪Shanita有孔虫动物群

系统研究了云南保山市卧牛寺附近大凹子组“破灰岩”中的Shanita有孔虫动物群,鉴定出其中特征分子Shanita和Hemigordiopsis8种(包括2新种,不含未定种和比较种),其他非有孔虫10属。研究结果表明,保山地区Shanita动物群的特征属和整体构成与缅甸、泰国和我国西藏等地的Shanita动物群相似,时代为茅口期晚期(冷坞期)至吴家坪期早期。但是,总体属级分异度较低,个别地方性种的出现及共生类的缺失,又使得保山地区的Shanita动物群具有一定的地域色彩。     

The Shanita fauna (Permian foraminifera) from Baoshan area, western Yunnan Province, China

Studies in the past decade have proven the Shanita fauna to be an excellent marker of the northern peri-Gondwana tectonic blocks. Thus, a study of the Shanita fauna from the Baoshan area in western Yunnan Province, China, could provide pivotal paleontological evidence for the paleogeographic reconstruction of the Baoshan block. We systematically analyzed the composition and the age of the Shanita fauna from the Permian Da’aozi Formation in Woniusi Section of the Baoshan area. Results suggested that the characteristic genera Shanita and Hemigordiopsis in this fauna comprised eight species (including two new species), and ten genera of other nonfusulinid foraminifera were also recognized from this fauna. Further comparative study showed that the Shanita fauna from the Baoshan area were probably late Maokouan (Lengwuan) to Wuchiapingian in age. In general composition, this fauna is comparable to those Shanita faunas from Shan State of Burma, Peninsular Thailand, and Nagri of Tibet, China. However, the relatively low generic diversity and occurrence of some endemic species, as well as the absence of fusulinids, indicate certain regional features of the Shanita fauna from the Baoshan area.

Llandovery sporomorphs and graptolites from the Manbo Formation,the Mojiang County,Yunnan, China

Llandovery sporomorphs and graptolites have been recovered from the Manbo Formation, Mojiang area, western Yunnan, China, which belonged to the Indo-China Palaeoplate in the Palaeozoic. The graptolite fauna, including 8 genera and 12 species, is considered Mid Telychian, Llandovery in geological age, confirming the existence of Llandovery rocks in this region. The Silurian stratigraphical sequence of this area is reconsidered as in the ascending order: Manbo Formation (Llandovery–early Wenlock), Shuiqing Formation (late Wenlock–Ludlow) and unnamed formation (Pridoli?). The sporomorph assemblage from the Manbo Formation includes seven species in five genera. The dominant members of this assemblage are Tetrahedraletes medinensis and Laevolancis chibrikovae. Based on the low diversity and low abundance, the geological age of this assemblage is considered to be approximately the Telychian, Llandovery. The parent plants of sporomorphs probably inhabited the landmass near Mojiang area, these sporomorph-producing plants probably included bryophyte-like land plants and primitive vascular land plants. The sporomorph evidence shows that the South China and Indo-China palaeoplates may have been in close proximity (maybe with some continental bridges linking them) to each other at least in the Llandovery. They were also closely related with Gondwanaland in the Llandovery.

Comparative Study of Ant Communities of Rehabilitated Mineral Sand Mines and Heathland, Western Australia

We conducted a survey of ants in April 1997 in seven rehabilitated (2- to 20-year-old) and three native heathland reference sites of the Renison Goldfields Corporation (RGC) Mineral Sands operations at Eneabba, Western Australia. We employed a variety of collecting methods, including pitfall trapping, litter and soil sampling, sweeping and beating of vegetation, and collecting by hand in the day and after dark, replicating those used by previous researchers in a similar study conducted in the same area in 1980. We found a total of 96 ant species representing 30 genera in 1997, compared with 46 species from 18 genera in 1980. Ant species richness increased with age of rehabilitation and exceeded that of heath controls by the time it reached 11 years. Ant species richness related to rehabilitation age was represented by a logarithmic curve, and the slope for current rehabilitation was steeper than that for the earlier rehabilitation studied in 1980. This probably reflects improved rehabilitation practices. Ordination of the sites in terms of ant species composition indicated differences between ant species in the rehabilitated sites studied in 1980 and 1997, and also between all rehabilitated sites and heath controls. Classification of the sites in terms of the distribution of ants across functional groups also indicated differences between rehabilitation and heath control sites. According to species composition and functional group profiles from rehabilitated and control sites, we concluded that although the current rehabilitation allows for a rapid return of ant species, even after 20 years the fauna still had not attained the composition of the original heath fauna.

Middle Permian smaller foraminifers from the Maokou Formation at the Tieqiao section,Guangxi, South China

This paper documents smaller foraminifers from the Maokou Formation (Guadalupian) at the Tieqiao section in Laibin area, South China. The assemblage of smaller foraminifers reported herein consists of 69 species of 42 genera. Although the Maokou Formation of this section was deposited in a relatively deep-water environment, smaller foraminifers are diverse and abundant, especially in debris flow deposits and thin turbidite beds. This fauna bears most similarity with coeval foraminiferal assemblages from the other Palaeotethyan regions. There is a sharp decrease in the diversity and abundance of smaller foraminifers at the lithological boundary between the Maokou and Heshan formations. An overwhelming majority of genera of smaller foraminifers that occur in the Maokou Formation at this section can be found in the Lopingian strata of South China. The study of smaller foraminiferal fauna of the Guadalupian at the Tieqiao section indicates a much less pronounced effect of the pre-Lopingian crisis on smaller foraminifers.     

贵州毕节麻窝口洞与智人伴生的长鼻类化石

最近在贵州毕节麻窝口洞发现了3枚古人类牙齿化石和伴生的哺乳动物群。其中,古人类牙齿经初步研究可归入解剖学上的现代人,而与古人类相伴的大、小哺乳动物化石,经初步鉴定共计8目20科43属53种。本文系统记述了该动物群中大哺乳动物的典型代表——长鼻类化石,共2属2种:东方剑齿象(Stegodon orientalis)和亚洲象(Elephas maximus)。麻窝口洞的长鼻类缺失我国南方早更新世的典型种类——中华乳齿象(Sinomastodon)和华南剑齿象(Stegodon huananensis),具有从典型的中更新世大熊猫-剑齿象动物群(Ailuropoda-Stegodon fauna)向晚更新世亚洲象动物群(Asian elephant fauna)过渡的特征。依动物群的性质和地貌地层的特征,毕节麻窝口洞的智人及伴生动物群的地质时代很可能为中更新世晚期或晚更新世早期,这与堆积物的光释光年代测定的初步结果(距今约11.2-17.8万年)基本吻合。麻窝口洞东方剑齿象与亚洲象的组合明显具有东洋界亚热带动物群的特点,指示温暖潮湿的气候,这些长鼻类与智人等生存于近水的森林和灌丛中,并镶嵌了一些草地。     

Early Silurian(Telychian)rugose coral fauna of Daguan area, northeast Yunnan Province,China

Study on rugose coral fauna of the Sifengya Formation(early Telyehian)and Daluzhai Formation (mid-late Telychian)in Daguan area,northeast Yunnan Province,China was carded out.Rugose coral fauna of the Sifengya Formation included 18 genera and 34 species,while Daluzhai Formation with nine genera,ten species.We described rugose coral fauna(12 genera,19 species)including one new genus and five new species,i.e.Protoketophyllum daguanense gen.et sp.nov..Crassilasma huanggexiense sp.nov.,Pseudophaulactis heae sp.nov.,P.convolutus sp.nov.,and Shensiphyllum minor sp.nov..The characteristics and geological significance of rugose coral fauna of Sifengya Formation and Daluzhai Formation were analyzed.Particularly,mgose coral fauna of the Sifengya Formation represent early Telychian rugosan fauna in the Upper Yangtze region and improve the sequences of early Silurian(Llandovery)mgose coral assemblages in Yangtze region.It is therefore very meaningful to further analyze radiation period of rugose coral fauna in such epoch.     

Rumen ciliated protozoan fauna of the yak (Bos grunniens) in China with the description of Entodinium monuo n. sp

Rumen ciliate species composition was surveyed in domestic yaks kept in Tibet, Sichuan, and Inner Mongolia, China. Twelve genera including 36 species with 18 formae were identified. The species compositions were slightly different among the three areas: yaks in Tibet had the simplest fauna, in contrast, the fauna of yaks in Inner Mongolia were the most abundant and similar to those found in the cattle kept in the same area. This suggests that the rumen ciliate composition of yaks is affected by that of cattle kept together or in proximity. A new species belonging to the genus Entodinium, Entodinium monuo n. sp., was recognized from the yaks in all areas. This new species was common in the yaks but was not detected in the cattle fed near yaks in Inner Mongolia. There was a similar generic ciliate composition in yaks kept in respective areas. Entodinium was the most predominate ciliate (51.9-61.0%) with total ciliate densities estimated as 10(5)/ml per yak.     

广西崇左泊岳山巨猿洞早更新世的鼠科化石

最近在广西崇左泊岳山巨猿洞采集到大量步氏巨猿、猩猩、长臂猿等高等灵长类及伴生的属种丰富的哺乳动物化石。本文系统记述了该化石点小哺乳动物群中的优势群体——鼠科化石:似锡金小鼠(Mus cf.M.pahari)、似大林姬鼠(Apodemus cf.A.peninsulae)、细狨鼠(Hapalomys gracilis)、狭齿狨鼠(Hapalomys angustidens)、先社鼠(Niviventer preconfucianus)、安氏白腹鼠(Niviventer andersoni)、拟爱氏巨鼠(Leopoldamys edwardsioides)和似始家鼠(Rattus cf.R.pristinus)共6属8种,其中包括了5个绝灭种。研究表明,泊岳山巨猿洞鼠类主要属种的形态特征显然要比同地区的三合大洞显得原始,而较相似于重庆巫山龙骨坡的相关鼠类,因此推测其时代为早更新世早期,这与古地磁的测年结果(距今约180万年)相吻合。泊岳山巨猿洞的鼠类大部分均为东洋界成员以及树栖、半树栖及林地生活的种类,反映当时的自然景观为热带-亚热带的森林-林灌环境。泊岳山巨猿洞鼠科化石的研究丰富了我国南方早更新世巨猿-中华乳齿象动物群中小哺乳动物化石的记录,这对于探讨我国南方第四纪生物地层的划分将提供重要的信息。

新疆准噶尔盆地周边晚石炭世的珊瑚*

新疆北部准噶尔盆地周边石炭系广泛出露, 其中上石炭统发育海相火山—沉积序列, 包括西准噶尔地区的哈拉阿拉特组、阿腊德依克赛组, 东准噶尔地区的石钱滩组以及盆地南部的祁家沟组、奥尔吐组等。本文研究在上述各地层的灰岩层或夹层、碎屑岩中获得的四射珊瑚9属17种和床板珊瑚2属3种, 对石钱滩组中的3个新种进行了详细的系统古生物学描述。上述珊瑚化石的地质时代主要为巴什基尔期至莫斯科期。在珊瑚动物群的组成上, 哈拉阿拉特组中新发现Caninophyllum属分子, 结合盆地东、西部共同产出的床板珊瑚Cystodendropora 属分子, 说明整个准噶尔盆地周边的动物群面貌大致类似, 而西准噶尔地区的化石丰度、分异度显著低于盆地东部和东南部。综合前人资料, 目前在准噶尔盆地周边发现的珊瑚化石有约一半为地方性分子。本文认为研究区珊瑚化石的分布和组成特征与晚石炭世准噶尔洋走向封闭或半封闭的演化趋势密切相关。
