Today, we have a very colorful Annularia inflata from the Mazon River. Annularia is some of the foliage from Calamites. It was described by Leo Lesquereux in 1870. For more information, see Mazon Monday #60.
This beautiful specimen was collected from the Mazon River by Jeremy Zimmerman. Thanks for sharing, Jeremy!
