    This is an interesting little brachiopod I found near Capon Lake, WV. I’m wondering what the holes all over the shell are. Maybe they’re actually bryozoans covering the shell? Or maybe they’re from a predator trying to dig into the shell? 🤔 #fossil

    • OHHHHH good guesses but I think I know the answer! Even better – punctae! These are little holes and peaks in the brachiopods shell that can create very complex geometric mesh patterns. I couldn’t find any good links quickly, all super technical stuff online. Can anyone second this idea?

    • I think I’ve seen something about punctate structure in some of Art Boucot’s notes and I agree with Jen.

    • @jbauer @mackenzie-smith Oh cool! I’ll look into punctae some more. Thanks!

      • Let us know if you get paywalled and we can try to help out with getting papers you may want. I haven’t gotten to look into it much more but it is a really fascinating aspect of morphology.

        • Awesome, thanks! My old copy of Treatise on Invertebrate Paleontology didn’t have much on it, so I’ll have to scrounge around.
