宾夕法尼亚时代约翰谷页岩的特征是丰富的腹足类、腹足类、腕足类、苔藓虫、介形虫、牙形刺和甲虫类。该地层与Pottsville群的下部相对应。根据Ulrich的限制，Caney页岩由带典型密西西比动物群的固结黑色页岩组成。本文共分两部分发表。第一部分将介绍钙质藻类、有孔虫、牙形虫、苔藓虫和介形虫。第二部分将介绍腹足动物、准足动物、腕足动物和头足动物。此外，还将提供化石图，显示其他相关地区的化石范围。
The Johns Valley shale of Pennsylvanian age is characterized by an abundance of nepionic cephalopoda, gastropoda, and brachiopoda, bryozoa, ostracoda, conodonts, and formaminifera. The formation is correlated with the lower part of the Pottsville group. The Caney shale, as restricted by Ulrich, consists of concretionary black shale carrying a typical Mississippian fauna. This paper is published in two parts. The first part will describe the calcareous algae, foraminifera, conodonts, bryozoa and ostracoda. The second part will describe the gastropoda, pelecypoda, brachiopoda and cephalopoda. Also a fossil chart will be given showing the ranges of the fossils in other correlative areas.
