Here are a few holocephalian teeth from the Pennsylvanian LaSalle Limestone from Illinois that I have been unable to ID. I find these teeth hard to ID since the tooth plates of a single species are often so varied in morphology, and I can rarely tell if I'm looking at a fragment or whole plate. Hopefully someone more experienced than I can tell. For the first tooth, I tooth a picture in situ before trying to split the boulder as I was afraid it would crack. Well it did unfortunately and I was only able to save a few pieces. This second tooth looks like Psammodus but I'd love a second opinion (or even a species identification if possible). And this third tooth looks like a fragment, but I really don't know. @Archie @deutscheben Let me know if you have any thoughts. Thanks.
