Thomas C. posted a topic in IllinoisI think this may be a mastodon fossil, but I have no real idea. I found it on a beach on north island, Kankakee River, Wilmington Illinois.
jmay posted a topic in Fossil IDFound all three of these at different times in Kankakee River State Park in Illinois. In the river. Two of them were just laying out. I got the other one hammering rocks. The rock it was embedded in was kind of a medium sandstone. (EDIT - I'm just attaching two because of the MB limit. You can see one of them from two different angles, including the interesting stuff in the middle, and the other from a single angle. I can post more if needed). I'm fascinated by the three-dimensional quality of these. The one - you can see pretty well - even seems to have some internal structure visible, looks like a notochord, but who knows. Anyway, at first I thought that I had Tully Monsters, until I learned those are never found in this form or location. Then I thought maybe I had ammonites, but apparently those are very rare in the Midwest, so I'm not so sure. What do we think?
