摘要 对从整个挖掘单元中回收并通过挖掘机在现场分类的鱼类区系与从同一单元中回收的柱状样本中并在实验室中借助显微镜进行检查的鱼类区系进行了比较。结果表明，较小的柱样品为确定所用物种的数量提供了充分的控制，并且通常通过显示未从较大单元中回收的较小物种个体的存在而超过整个单元分析。小样本的显微镜检查似乎为常用的鱼类动物群取样方法提供了急需的补充。
Abstract Comparisons were made between fish faunas recovered from entire excavation units and sorted in the field by the excavators and fish faunas from column samples recovered in the same units and examined in the laboratory with the aid of a microscope. The results indicated that the smaller column samples provided adequate control for defining the number of species utilized and often surpassed the whole unit analyses by showing the presence of smaller individuals of species not recovered from the larger units. Microscopic examination of small samples appears to provide a much needed addition to the commonly utilized methods of sampling fish faunas.
