Unknown Mazon Creek Fossil

[trilomike]

Hello Everyone:

I have been a fan of the Fossil Forum for sometime now. Love the posting and sharing of information. It is always exciting to see all of the finds here.

I have been collecting at ESCONI hill outside Braidwood, Illinois several times this past year. I have been freezing and thawing numerous nodules but only finding wood fragments. Did find some nice smaller cordaites.

However, a couple of weeks ago, I cracked the attached nodule and it produced a nice 3d fossil. However, it has me puzzled. I have been searching through "The Mazon Creek Fossil Fauna" by Jack Wittry, 2012.

Any information would be greatly appreciated. Thank you.

Welcome to the forum!

I cannot make out much detail from the pictures. I do see what appear to be possible legs.

If I had to take a guess, I would think it might be a partial shrimp.

If you are a member of ESCONI, bring it to a meeting and someone can probably figure out what you have.

Thanks Rob.

I thought might be a shrimp, its just that the tail appears to look different than a shrimp. I do want to try to make the ESCONI meetings, however there had always been a conflict.
