We’ve been on a Alethopteris theme lately with last week Friday’s Alethopteris serlii from the Field Museum and Monday’s Species Spotlight on Alethopteris sullivantii.  We’ll finish up this week with a brand new specimen of Alethopteris sullivantii.  This specimen was collected a maybe five years ago in the famed Pit 2 of the Mazon Creek fossil locality.  It sat in a bucket until last Fall, when it finally was placed in a container to go through the freeze/thaw process.  A few days ago it finally opened… and here it is!
