Mazon Monday #292: Mazon Creek Fossil Day 2025

This is Mazon Monday post #292.  What’s your favorite Mazon Creek fossil?  Tell us at email:esconi.info@gmail.com.


We had a nice turnout at the Mazon Creek Fossil Day event in the Coal City library a few weeks ago. There were multiple displays by members and people brought in some of their finds for identification. Last week’s Fossil Friday was an absolutely beautiful shark egg case (Palaeoxyris multiplicatum, see Fossil Friday #287).

There were plenty of familiar (smiling) faces.

There were many fossil discussions and Jack Witty was there. He gave us a quick update on the new Mazon Creek animal book he’s been working on.

Now on to some fossils!
