Maybe it’s the size or the 3 dimensional preservation, but this is at least the second Alethopteris serlii specimen that has made it onto Fossil Friday.   This awesome fossil was found by Brandon Bergsten at the I&M Canal Corridor Mazon River Fossil Trip back in August 2020.  It only took a few weeks of freeze/thaw to get this concretion open.  Congratulations, Brandon!
