I have found several of the common fossils available in the book locally. However, the state differs in geologic age and you’ll find different fossil families in different geographic locations. For example, central Pennsylvania is a much better place to find large Trilobites, a favorite among fossil collectors.

Others States but Useful Here
Several other states have publications that are useful in Pennsylvanian. New Mexico, Arizona, Kansas, Texas, Illinois, Kansas, Nebraska, Iowa, Ohio, Kentucky, and West Virginia all have relatable stratum that correlates with stratum locally. The same floods that brought ancient seas to Western Pennsylvania also flooded the land with water in these places. While the Brush Creek limestone locally is only a foot or two thick, so places have it tens of feet thick from the same time period.
