    Sadly, there aren’t enough features preserved for me to say if it’s a fossil or not. However, there are the two large black parts and smaller striations which makes me think wood and there are divots or holes in it so it could be terredo wood. Just due to the nature of the preservation it’s just too hard to say.

    Hi @everett-snyder. You said this is from the Cannonball Formation? So this is from around North Dakota?

    @bob-jones I think it might be Lirophora

    It looks like two different colors of chert laid down one after the other. Sorry!

    @bob-jones@rens-dewaard This is definitely a clam cast. It may take some time for me to find the name though.

    @hunter-thurmond Calamites went extinct around the Triassic but their nearest living relatives in the genus Equisetum (same genus as modern horsetail) were around in the Paleogene. It’s possible it could be that. Can you remove some of the matrix? One of the key features is a node which might be covered right now. A cross section photo would help…[Read more]

      @mackenzie-smith I can’t figure out how to add more photos or post photos in a reply. I will create a new post once thorough pictures have been made. I was able to remove most of the matrix but no node seems apparent. Is the last picture of this post a sufficient cross section? Where it is fractured it reminds me of petrified wood I have found…[Read more]

    @robin-loggains and @samantha-ocon Personally, I’m leaning towards septarian nodule with the original matrix eroded out but it’s a tricky one.

      Oh! Good point – the only thing I’m noticing is the tiny little star at the bottom

    @delwin-glasner Very neat! I was unfamiliar with Endopachys. The only solitary scleractinian coral I encountered before was Flabellum. Thanks for sharing! Glad I learned something new.

    To me this looks like horn coral. I think this is another photo in a series, yes?

    Sorry, this is a rock. For fossils, we need to match the texture and shape to something known either living or fossil. It looks like the top is calcite and the bottom is probably a course limestone.

      I agree – this is a rock unfortunately.

    It’s a fossil but not a pirhana. Probably some sort of invertebrate like a crinoid stem or cephalopod or even a colonial animal. The rock sort of obscures the view.

    @robin-loggains It looks like a rock to me but the piece to the right of it is horn coral.

    This looks like a fragment of rugose coral.

    Looks like it could be a fragment of some Echinodermata based on the patterns of the depressions.

      Unfortunately, I have to agree with @Mackenzie-Smith – this is cement.
