This weekend, May 15th and 16th, 2021, ESCONI returns to the Braceville spoil pile to collect Mazon Creek fossils and concretions. Last fall, we had a couple posts to show what has been found there in the past - Fossil Friday #22 and Fossil Friday #23. Today, we are going to revisit those specimens for the new visitors on this trip. Good Luck!
Animals
Animals are much more common than plants at Braceville. Jellyfish are the most plentiful, but many worms have been found. In fact, many people refer to the Braceville spoil pile as "Worm Hill".
Octomedusa pieckorum (Jellyfish)
Kallidecthes richardsoni (Shimp)
Palaeoxyris sp. (Shark egg case)
Essexella asherae (Jellyfish)
Paucijaculum samamithion (Arrow worm)
Dryptoscolex matthiesae (Rat worm)
Mazonomya mazonensis (Clam)
Aviculopecten mazonensis (Scallop)
Mazopherusa prinosi (Fan worm)
Plants
While relatively rare compared to animals, there has been a good variety of plant fossils found at Braceville.
Stygmaria
Laveiniopteris rarinervis
Alethopteris sullivantii
