ESCONI member Phil Anderson sent us a very interesting fern from the ESCONI field trips to a Danville spoil pile. This is a specimen of Lobatopteris tenuinervis, which is a fern in the order Filicopsida. You can read more about the flora of the Herrin coal in Mazon Monday #86.
This gorgeous specimen has great color contrast. The concretion is very thin, much thinner than what is usually seen. Thanks for sharing this beautiful fossil, Phil!
