竹柏类植物的RAPD分析

对鸡毛松（Ｐｏｄｏｃａｒｐｕｓｉｍｂｒｉｃａｔｕｓ）、竹柏（Ｐｏｄｏｃａｒｐｕｓｎａｇｉ）、长叶竹柏（Ｐｏｄｏｃａｒｐｕｓｆｌｅｕｒｙｉ）、百日青（Ｐｏｄｏｃａｒｐｕｓｎｅｒｉｆｏｌｉｕｓ）和罗汉松（Ｐｏｄｏｃａｒｐｕｓｍａｃｒｏｐｈｙｌｕｓ）进行了ＲＡＰＤ分析。经筛选４组８０个引物,发现９个引物的带型清晰并呈多态性。采用ＵＰＧＭＡ法对求出的遗传距离进行聚类分析,得到的结果显示：本研究中的植物明显地分为３个亚类群,支持在罗汉松属内建立竹柏组的处理方式,不同意把竹柏类从罗汉松属中分离出去成立新科的观点

Studies on the Fusinized-Wood Fossils of Podocarpaceae from Huolinhe Coalfield,Inner Mongolia,China

Some fusinized-wood fossils from seam 14 and seam 17 of Lower Coal-bearing Member of Huolinhe Formation in Huolinhe Coalfield were observed and described. They were as- signed to Podocarpoxylon dacrydioides sp. nov., Podocarposcylon sp., Phyllocladoxylon sp. 1 and Phyllocladoscylon sp. 2. P odocarpoylon and Phyllocladoxylon were two types of ancient wood fossils of Podocarpaceae. That both of them were found in Huolinhe Coalfield, seven among the twelve observed specimens belonged to the former, and the others to the latter, indicating that the plants of Podocarpaceae might be the main coal-forming plants in the coalfield.     

Fossil Woods From Williams Point Beds, Livingston Island, Antarctica: A Late Cretaceous Southern High Latitude Flora

The wood flora from Williams Point, Livingston Island, contains 12 wood types of gymnosperm and angiosperm origin. Recent collections of material have increased the biodiversity of a postulated species-rich vegetation. The gymnosperm wood can be readily assigned to four form-genera: Araucarioxylon Kraus, Araucariopitys Jeffrey, Podocarpoxylon Gothan and Sahnioxylon Bose and Sah. This indicates a diversity of coniferous araucarian and podocarp trees alongside woods of uncertain affinity ( Sahnioxylon ; Bennettitales). Two angiosperm morphotypes are assigned to the organ genera Hedycaryoxylon Su¨ss (Monimiaceae) and Weinmannioxylon Petriella (Cunoniaceae). The remaining four taxa of angiosperm wood cannot be confidently placed in extant families as they exhibit features that suggest relationships with the Magnoliidae, Hamamelidae and Rosidae. This paper presents the first comprehensive taxonomic revision of the wood flora from Livingston Island and discusses the palaeoecology that prevailed at a latitude of about 60 degrees south during the Late Cretaceous. Newly described taxa are Araucarioxylon chapmanae sp. nov., Araucariopitys antarcticus sp. nov., Podocarpoxylon chapmanae sp. nov., P. verticalis sp. nov., P. communis sp. nov., Weinmannioxylon ackamoides sp. nov., Antarctoxylon livingstonensis gen. et sp. nov., A. multiseriatum gen. et sp. nov., A. heteroporosum gen. et sp. nov. and A. uniperforatum gen et sp. nov.

Cretaceous (Late Albian) coniferales of Alexander Island, Antarctica. 1: Wood taxonomy: a quantitative approach

Silicified conifer woods are very common in the mid-Cretaceous (Late Albian, 100Ma) Triton Point Member of the Neptune Glacier Formation (Fossil Bluff Group), SE Alexander Island, Antarctica. These occur as up to 7m high in situ tree trunks and stumps rooted in carbonaceous palaeosols and as allochthonous logs and wood fragments in fluvial channel and sheet sandstone facies. Sixty-eight wood samples were examined in this study and were classified in terms of five form taxa using a quantitative approach. Araucarioxylon (1.5% of specimens) is characterised by dominantly multiseriate, alternately arranged bordered pitting on radial tracheid walls and by 1-4 araucarioid cross-field pitting. Araucariopitys (11.8% of specimens) is characterised by dominantly uniseriate tracheid pitting with subordinate biseriate, alternate tracheid pitting and by 1-4 araucarioid cross-field pitting. Podocarpoxylon sp. 1 (63.1% of specimens) is characterised by contiguous, uniseriate tracheid pitting and 1-2 podocarpoid cross-field pits. Podocarpoxylon sp. 2 (22.1% of specimens) is similar to P. sp. 1, differing only in that ray height is lower, tracheid pits are dominantly spaced more than one pit diameter apart and abundant axial parenchyma is present. These first four taxa all possess growth rings with subtle boundaries. Taxodioxylon (1.5% of specimens) is characterised by 1-2 seriate, oppositely arranged, bordered tracheid pitting, 1-2 taxodioid cross-field pitting and very marked ring boundaries. These woods were derived from large trees with basal stump diameters of up to 0.5m and probable heights of up to 29m. Data from leaf traces suggest that Araucariopitys and Podocarpoxylon sp. 1 and sp. 2 (97% of specimens) were evergreen with leaf retention times of >5years. These predominantly evergreen conifer forests grew in a mild, high latitude (75 degrees S) environment during the mid-Cretaceous greenhouse climate phase.

云南中甸新发现的早更新世哺乳动物

描述了最近发现于横断山脉中段的一批哺乳类化石 ,具体地点位于云南迪庆州中甸县城 (香格里拉 )以南约 6km处的公路旁。这批材料包括灵长类 (Procynocephaluscf.P .wimani)、啮齿类 (Hystrixsp .)、食肉类、奇蹄类 (Equusyunnanensis)及偶蹄类 ,其中以鹿类 (Cer vavitusultimus、Eucladocerossp .、Cervus (Rusa)yunnanensis等 )和牛羊类最为丰富 ,揭示了当时一种混合的森林 -草原环境。从动物群总体面貌来看 ,这批哺乳类可与元谋人动物群相比 ,时代为更新世早期。但其中有些种类与北方早更新世类群相似 ,如真枝角鹿及羚羊等 ,表明该动物群也与北方动物群之间存在着某种生物地理上的联系。     

陕西镇安黄家湾早更新世哺乳动物群及其伴生植物

记述了发现于陕西镇安黄家湾早更新世晚期的一个大型哺乳动物群。动物群包括哺乳动物4目、11科、24种,它们是：Canis variabilis, Hyaenidae gen. et sp. indet. , Homotherium sp. , Megantereon sp. , Lynx cf. shansius , Panthera pardus , Elephantidae gen. et sp. indet. , Equus qingyangensis , Hesperotherium sinense , Ancylotherium sp. , Megatapirus augustus, Rhinocerotidae gen. et sp. indet. , Dicerorhinus lantianensis, Sus sp. , Moschus moschi ferus , Cervus unicolor , Cervus sp. 1, Cervus sp. 2, Hydropotes sp. , Capreolus sp. , Strepsiceros annectens , Leptobos sp. , Bubalus sp. 和 Budorcas taxicolor等。动物群伴生植物孢粉分析表明,当时在化石产地生长着下列植物：Selaginella sp. , Pinaceae gen. et sp. indet. , Picea sp. , Cotinus coggygria , Juglans regia , Quercus sp. , Myrica rubra , Meliaceae gen. et sp. indet. , Celtis sp. , Oleaceae ( Syringa sp. ?) gen. et sp. indet. , Chenopodiaceae gen. et sp. indet. ,Kobresia sp. , Scrophulariaceae gen. et sp. indet. , Humulus sp. , Gramineae gen. et sp. indet. , Ranunculaceae gen. et sp. indet. , Sparganium sp. ,Celastraceae gen. et sp. indet. ,Elaeagnaceae gen. et sp. indet. ,Compositae gen. et sp. indet. ,Aremisia sp. , Xanthium sibiricum 和Carex sp.等。分析了动物群生活时栖息地的气候、植被和地貌特征,结果表明,动物群栖息在温暖、湿润、有森林、灌丛草地并富有水体的生境中,当时秦岭腹地存在着相当开阔的河谷地带,山势没有现在这么险峻,因此阻断秦岭南北动物交流的天然屏障当时可能还未真正形成,秦岭南北两侧的动物可以沿着开阔的河谷地带随季节和气候的变化互相扩散迁移。

The Feature of Fossil Plants from the Lower Cangfanggou Group of Upper Permian,Northern Xinjiang

This paper deals with the Fossil Plants from Upper Permian in Northern Xinjiang. These plants include 25 species of 15 Genus. Five new species is all described in this paper. These are: ?Supaia serrata sp. nov. Tychtopteris densinervis sp. nov., Ty. obesa sp. nov., Comia Cangfanggouensis sp. nov. and Lepeophyllum ovatum sp. nov. These are all new to science, found in the Lower Cangfanggou Group in Northern Xinjian, of Late Permian in age. Some fossils Lobatannularia multifolia Ken'no, Sphenopteris rotunda Sze and Alethopteris huiana Lee found in this group are known in the Cathaysian Flora. Others are common in the Angara Flora, such as Stellotheca sehtchurowskii (Schmal.) Surange et Prakash, Sphenopteris, adzvensis Zal., Tychtopteris cuneata (Schmal.) Zal. Noeggerathiopsis sp., ect. That indicates in the Lower Cangfanggou Group is a transitional zone between the Angara and the Cathaysian floras.     

云南禄丰古猿化石地点的豪猪化石

描述了产自云南禄丰古猿化石地点的豪猪化石禄丰豪猪 (新种 ) (Hystrixlufengensissp .nov.)。这是一种较原始的豪猪。它的个体中等 ;两上颊齿列往前靠近 ;下颌骨骨体较低 ,齿隙稍凹 ,其前端高于下颊齿冠面 ;颊齿齿冠较低 ;上颊齿舌侧沟横向较短 ;P4大 ,前尖通常孤立 ,中附尖很发达 ,不与中脊连 ;M3较少退化 ;上颊齿具 3齿根 ,大的内侧齿根具明显纵沟 ;下颊齿通常具 4齿根等。形态结构分析表明 ,H .lufengensis仅比H .parvae进步 ,比H .primigenia和H .sivalensis及其他种都原始。它可能代表亚洲目前已知最早、最原始的豪猪。其产出时代为晚中新世保德期 (狭义 )的较早期 (距今约 8Ma)。
