Pennsylvanian Ferns From Missouri & Kansas

[fiddlehead]

Thank you for pointing out the overlying (unnamed) shale of the Croweburg Formation's coal is in the Verdigris Formation. I should have been more clear on that.

For further reading on the relationship of the Croweburg coal in Missouri to the Mazon Creek area see;

Thanks everyone for the links. Perhaps it's time to continue to expand my library.
