中国辽宁早白垩世华夏翼龙（翼龙目：翼手龙亚目）一新种及古神翼龙科的系统分类

根据中国辽西早白垩世九佛堂组一几乎完整头骨及头后骨骼建立古神翼龙类一新种：具冠华夏翼龙。具冠华夏翼龙以前上颌骨上具有一斧状矩形突起为特征，该突起的短轴垂直于前上颌骨的前边缘，除了该突起之外，其他的头骨特征比如鼻眶前孔的前边缘和前上颌骨的前边缘之间的吻部宽度均与季氏华夏翼龙的相似。华夏翼龙和中国的另一个古神翼龙类中国翼龙与古神翼龙共享有一些独特的头骨特征，并且这3个属看起来彼此之间的关系要比与其他神龙类密切的多。中国的古神翼龙（中国翼龙和华夏翼龙）具有相对长的头骨和弱的头骨嵴，而且似乎要比头骨短高和具有大的头骨嵴的古神翼龙原始。Tupuxuarids（Tupuxuara和Thalassodromeus）经常和古神翼龙类被放在古神翼龙科中，     

蓝鲸

<正>蓝鲸被认为是地球上出现过体型最大的动物。它的舌头大约重3吨,当它全部伸展开来时可以攫取100吨重的食物与海水。即使拥有这样巨大的嘴,蓝鲸的喉咙仍然无法吞下沙滩球那样宽的物体。它们的心脏重600千克,也是已知的生物中最巨大的。蓝鲸的主动脉则大约23厘米宽。在出生后的7个月内,幼鲸每天要喝400升的母乳。幼鲸的生长速度很快,体重每24小时增加90千克。即使才刚出生,幼鲸的体重就能达到2,700千克——相当于一只     

海南岛扇肢亚目的补充记述

20世纪50~80年代以中国科学院海洋研究所为主，曾对海南岛进行了数次生物调查，包括：全国海洋综合调查(1958~1960年)，南海中部、东北部综合调查(1974~1985年)，全国海岛资源综合调查(1989~1993年)，中德海南岛生物联合考察(1990，1992年)及中日海南岛浅海动物多样性联合考察(1997年)等，获得了大批珍贵的海洋生物标本，这些标本基本上保存在中国科学院海洋研究所标本馆内。本文作者(Yu et al，2001)经对其中的甲壳动物等足类的整理，已记述了扇肢亚目浪飘水虱科和团水虱科的10个种。本文补充记述该亚目的4科13种，其中4种为中国海域新记录种。迄今为止，海南岛共发现扇肢亚目等足类23种，名录如下(其中*为本次补充种；**为中国海域新记录种)。

The first dinosaur tracksite from Xinjiang, NW China （Middle Jurassic Sanjianfang Formation, Turpan Basin） a preliminary report

A new dinosaur tracksite was discovered in a steeply inclined sandstone layer of the Middle Jurassic Sanjianfang Formation in the Shanshan area of the Turpan Basin. The site is the first record of dinosaur footprints from Xinjiang Province in northwestern China. More than 150 tridactyl theropod dinosaur footprints are preserved as positive hyporeliefs on the lower bedding plane of a fine-grained sandstone body. Most of the footprints are isolated and appear to be randomly distributed. Some show well defined phalangeal pads, heels and rarely indistinct impressions of the distal part of the metatarsus. Two distinct morphotypes are present: a larger type with relatively broad pads shows similarities to Changpeipus and Megalosauripus, and a slightly smaller, slender and gracile type which is similar to Grallator, Eubrontes and Anchisauripus. In both morphotypes, digit III is the longest with a length between 11.4 and 33.6 cm. A single imprint shows prominent scratches, probably formed during slipping of the track maker.

A Large Therizinosauroid （Dinosauria： Theropoda） from the Early Cretaceous of Northwestern China

We herein describe an associated partial postcranial skeleton of a theropod dinosaur discovered in the Lower Cretaceous Xinminpu Group of the Yujingzi Basin, in the Jiuquan area of Gausu Province, northwestern China. Features of its humerus, such as strongly expanded proximal and distal ends, a well developed medial tuberosity, distal condyles expressed on the humeral cranial surface, and a hypertrophied entepicondyle, definitively establish the therizinosauroid affinities of the specimen. It differs from other therizinosauroids in having a shallow, poorly demarcated glenoid fossa with a prominent rounded and striated tumescence on the dorsomedial surface of its scapular portion, and a pubis with a strongly concave cranial margin. It represents a new taxon, Suzhousaurus megatherioides gen. et sp. nov. Cladistic analysis recovers Suzhousaurus as the sister taxon of Nothronychus mckinleyi from the mid-Cretaceous of western North America; together, they are basal members of the Therizinosauroidea, more derived than the Early Cretaceous Falcarius and Beipiaosaurus but less derived than Alxasaurus and the Therizinosauridae. Along with ＂Nanshiungosaurus＂ bohlini from possibly coeval beds in the Mazongshan area of northern-most Gansu, Suzhousaurus represents one of the largest-known Early Cretaceous therizinosauroids, demonstrating that this clade attained considerable body size early in its evolutionary history.     

New Material of Sinosauropteryx （Theropoda： Compsognathidae） from Western Liaoning, Chinae

An incomplete specimen of Sinosauropteryx prima collected from the Early Cretaceous Yixian Formation of the Dawangzhangzi area in Lingyuan, western Liaoning is depicted. It represents the first systematically described material of this feathered compsognathid outside the Sihetun area in Beipiao. This specimen shows some diagnostic features of Sinosauropteryx prima, such as the very short forelimb in relation to hindlimb with the length ratio of humerus plus radius to femur plus tibia just around 30%, and the long and massive first manual ungual subequal in length to radius. The presence of Sinosauropteryx prima only at Sihetun and Dawangzhangzi supports the suggestion that the fossil-bearing beds in the Sihetun and Dawangzhangzi areas are equivalent to each other within the Yixian Formation.
