Does Anyone Know What This Is

[Lewand]

I think it might be a trilobite. Was found in Illinois. Any help would be good. I am new to this. Thanks.

Looks more like a coral.

[Lewand]

Maybe. It looks like it has a backbone to it and parts are crystalized. But I really don't know what I'm looking at. Thanks for your input.

I think it is a section through a horn coral:

Yea it looks a lot like that pic. Found around this was a lot of what looks like too a lot of Crinoidea stems. They go together don't they?

Here are some examples

Yes, corals and crinoids were associated, as both were marine critters.

You have some nice "hash plates" with different items all fossilized together.

The little bits of Crinoids are the Columnals, which make up the stalk of the Crinoid.

Your other bit is definitely a very worn/eroded rugose, or "horn" coral.

If you can tell us roughly, what county or town it was found in,we might be able to determine the age of the sediments in that area.

Neat finds. Keep looking - you are on the right track to find a trilobite.

And, welcome to the Forum.

On the Illinois river in Calhoun county. Thanks for the input I greatly appreciate it. I have lots of huge what you call "hash plates" with big Crinoidea stems. I'm getting excited to fossil. Thanks

I agree with the others.

Nice finds.
