After a long week, it’s time for Fossil Friday.  Another Mazon Creek fossil is up today.  This time it’s a worm, long called the leech by collectors, it’s now thought to be an echiuran – species name Coprinoscolex elliogimus.  The identifying evidence are the oval shaped fecal pellets visible in the fossil.  This one was found this spring in Pit 11.
