Alethopteris Of Saint Clair

Alethopteris are quite common at Saint Clair location. But apparently there are at least 6 different species.

These are all from "Fossil Plants from the Anthracite Coal Fields of Eastern Pennsylvania."

A zip file that contains the PDF can be downloaded from http://www.dcnr.state.pa.us.

Here's a direct link.http://www.dcnr.stat...dcnr_016425.zip
