Nimravis Posted January 26, 2019 Share Posted January 26, 2019 It is so cold in the Chicagoland area I decided to go through fossils that I have not looked at in years. I came across a little container that contained a couple items that I collected back in the early 90’s. I am 99% sure that I collected thenm from the Pierre Shale along I-90, West of Wall Drug. I know there is a small portion of an Ammonite, but I wonder about the other pieces. I believe they all came out of the same concretion. 5 Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted January 26, 2019 Share Posted January 26, 2019 The last one is part of an inoceramid bivalve, I think. The one before maybe a very weird scaphitid ammonite? 3 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
FossilDAWG Posted January 26, 2019 Share Posted January 26, 2019 Check out Yezoites for the wierd scaphitid. I don't think I've ever heard of that genus coming from the Pierre Shale, though. Don 1 Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted January 26, 2019 Share Posted January 26, 2019 Looks like Pierre Shale stuff to me. I have quite a bit of it myself. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
