Fissiletag Posted January 20, 2023 Share Posted January 20, 2023 I found a couple of fossils this summer in Rochester Minnesota at Quarry Hill nature center. I'm wondering if anyone regonises some of them. They are all Ordovician in age. 1. Unknown 2. Trilobite? 3. Trilobite? 4. Trilobite for sure. Anyone know the genus or family 5. Trilobite? 6. Shell or something else? Link to comment Share on other sites More sharing options...

Fissiletag Posted January 20, 2023 Author Share Posted January 20, 2023 Thank you. I wasn't expecting a Thaleops. It was my second time fossil hunting so I'm really happy. Link to comment Share on other sites More sharing options...
