Science. 1965 Jun 25;148(3678):1719-21. doi: 10.1126/science.148.3678.1719.

A considerable variety of bacteria and similar microorganisms are present as preserved remains in pyrite samples of Pennsylvanian age obtained from the coal measures of southeastern Ohio. The types observed are similar to the present-day microflora found in stagnant pools of low oxygen and nutrient content.

在从俄亥俄州东南部的煤炭区采集的宾夕法尼亚纪的黄铁矿样本中，存在着大量的细菌和类似的微生物，它们作为保存的遗迹存在。观察到的类型与目前在低氧和低营养含量的停滞池中发现的微生物区系相似。
