Addish Posted January 23, 2022 Share Posted January 23, 2022 These are two specimens I have found that I can’t confidently identify. I don’t know exactly where they are from but the sedimentary rock they are preserved in is likely from the Mississippian. I live in Northeast Alabama where there are quarries that extract shale and limestone from the Mississippian. Since I don’t know the exact locality they came from I cannot provide an exact time period. One is a white, wedge shaped fossil that I speculate might be a leaf. The other I am unsure of if it is even a fossil but it appears to be a fish, but it could just be crystals that formed in the shale. Link to comment Share on other sites More sharing options...
FranzBernhard Posted January 23, 2022 Share Posted January 23, 2022 Welcome to TFF from Austria! 3 hours ago, Addish said: white, wedge shaped fossil It seems to be 3D, so it could be a steinkern (internal mold) of a "shell fossil", but that´s only a vague guess. 3 hours ago, Addish said: but it could just be crystals that formed in the shale. You are spot on . Franz Bernhard 1 Link to comment Share on other sites More sharing options...

Fossildude19 Posted January 23, 2022 Share Posted January 23, 2022 Definitely not a leaf on the first - possibly a calcite filled bivalve or brachiopod. The second is just a crystal layer.
