The broken piece looks to have piece of Trilobite with it. Thanks for your help. Link to comment Share on other sites More sharing options...

Rockwood Posted October 20, 2018 Share Posted October 20, 2018 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. 1 Link to comment Share on other sites More sharing options...
Johnnyp323 Posted October 29, 2018 Author Share Posted October 29, 2018 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.
