I started writing this book in 2022. It is a publication dedicated to the Late Pennsylvanian fossils found in the Glenshaw formation, focusing on two Armstrong County sites. It is a work in progress; I felt it would serve a greater purpose online than sitting in an unpublished file.
The preface provides more information. You can also start using any of the major sections: Trilobita, Crinoidea, Bivalvia, Cephalopoda, Gastropoda, or Brachiopoda.
Last, much of this is unfinished. You’ll find sections with limited photography or text; some genera are still in the process of being started. The footer below should be present on every page, allowing you to use it as an anchor to browse sections.
