This paper describes the form of biota with eharophytes and ostracodes as ma- in groups discovered in s_3—s_4 in Tertiary Shahejie formation in Dongpu depressi- on,and the distribution of such group characterized in some formations both at home and abroad.The characteristics of comtempreneous occurrence of Obtusoch- ara jianglingensis,Gyrogona qianjiangica in charophytes and Cyprinotus ig- neus in ostracodes can be correlated to the those discovered in Middle Eocene Da- cangfang series in Nayang basin,predominance of Cyprinotus altilis in ostreco- des in upper S_4-lower S_3 can also be found in h_3-h_2 of Hetaoyuan formation and can be correlated,index fossils,such as palibinia pinnatifida,P.latifolia,P. korowinii and Knigntia sp.in plant and fish fossils have been found in upper s_4 and s_3,along with Austrocypris levis,Huabeinia chinensis in Ostracodes.The- refore it is considered that the age of these formation is in Late Eocene.

本文记述了东濮凹陷早第三纪沙河街组四至三段以轮藻、介形类为主的生物群面貌及其在国内外的分布情况,并较详细地讨论了沙河街组四段下部轮藻化石种 Obt-usochara jianglingensis,Gyrogona qianjiangica 与介形类化石 Cyprinotus igneus 共生为特征,可与南阳盆地中始新世大仓房组的生物群相对比;沙河街组四段上部至三段的具反迭覆的介形虫化石优势种 Cyprinotus altilis 的类型,在南阳盆地核桃园组三至二段也十分繁盛,两者亦可进行对比。另外,对地质时代富有指示性的植物化石和鱼化石 Palibinia pinnatifida,P.latifolia,P.korowinii,和 Knignlia sp.分别与沙河街组四段上部和三段的标志性介形类化石 Austrocypris levis,Huabeinia chinensis共生,其时代为晚始新世为宜。

行蜕壳式增长的节肢动物个体发育及性双形特征的研究必须建立在其化石种群结构的恢复之上。简单的数理统计是揭示其种群结构特征的钥匙:鉴别是否属正常化石种群,确定蜕壳期数,解释早期幼壳高死亡率与其化石低保存牢的统一。高肌虫个体发育常表现为六至七期明显的蜕壳阶段,蜕壳期间壳体增长率常在性成熟期有显著的减小趋势。物种的正确鉴定及性双形特征的辨识也只有通过个体发育研究才能得到合理的解决;物种在个体发育过程中表现出来的性伏变化,为研究谱系的演化趋向提供重要依据。这种数理统计方法无疑对三叶虫、介形虫等其他节肢动物的个体发育及性双形研究也完全适用。
