Recommended Posts

Found these rolled fossils in the Decorah Shale, St. Paul, MN. Tan colored and measures 2.0 cm long by 1.2 cm wide. The broken piece looks to have piece of Trilobite with it.

 

Thanks for your help.

possibly gastropods. One looks like a bellerophontid type

The one on the left looks like a gastropod steinkern. There is also a mold of a bryozoan colony that was living in the empty shell.

The one on the right looks like an ammonite hugging a piece of trilobite pygidium.

Thanks for your insight guys.  It is greatly appreciated.  

 

These were difinately out of the ordinary for the fossils I was finding in the area.  After digging into your suggestions the possible IDs make much more sense.
