Today we have a nice Cyclopteris orbicularis from the Mazon River.  This was collected a few years ago during one of the I&M Canal Corridor Fossil Trips.  Cyclopteris is associated with the mid-story seed ferns.  For more information, check out “A Comprehensive Guide to the Fossil Flora of Mazon Creek” or have a look at Mazon Monday #59.
