The preservation isn’t the best. Broke open a big piece of dolomite with a nice brachiopod. Found that I had shattered whatever this is and exposed some nice silicified chain coral. It’s sorta a hemisphere with internal structures. My best guess would be some sort of echinoid. Silurian Wisconsin, Hartung quarry

Hello, Here are a bunch of old collection fossils that have me stumped...almost no info on provenance so tricky, but I'm hoping I can get at least a fossil identity for them if possible. There are 13 in total, here goes: 1. Crustacean/brachiopod steinkern? 2. Crustacean? Brachiopod? 3. Is this a coral? 4. No clue...thought orthocone but seems too thin? 5. No clue 6. Thought some sort of echinoderm but almost looks six-sided? Reminds me of a construction nut used for screws. 7. Some sort of brachiopod? 8. This seems like a trilobite pygidium, appears to be on a white block of matrix? Any guesses as to specific ID? 9. These seem echinoderm. The one with the protrusion in the center might be an echinoid plate, the rest crinoid plates? 10. I'm guessing these are echinoid spines 11. Looks like some heteromorphic ammonite sections. The one on the right with a double row of tubercles might be Nostoceras or Didymoceras? 12. I'm pretty sure these are Conulariids but does the preservation inform the provenance or ID further? EDIT: one more: 13. Orthocone? Thanks!

Found on the railroad tracks. Confident it’s an echinoderm based on the apparent pentaradial symmetry. Heart urchin? Probably Ordovician to Silurian stone. Definitely Paleozoic.

Looking for help with ID on these two finds from the Peace River, FL. Closest I could come to an ID on #1 is an Echinoid. On #2 I am thinking it could be a giant tortoise leg spur? Any input would be appreciated.

I'm not sure what this is. Looks like a little fossil cauliflower. Echinoid, coral, or neither? Sw Fl, pliocene. Any help appreciated.
