This tooth was labeled as Orodus but I wanted to get some other opinions. I see quite a few different Paleozoic tooth morphologies that are called Orodus which can be a little confusing. I am not saying the Orodus ID is incorrect but I see some things that remind me of a Hybodontiformes tooth. Burlington Limestone Biggsville Quarry Biggsville, Illinois The tooth measures 5mm across.

Hi, I found this little tooth today in some more limestone. Its the smallest yet, and I'm kind of surprised I even saw it. My eyes are trained to see calyxs not these lovely teeth, so it's a great treat to find it. I'm also pretty new with these teeth, so I'd rather not guess and figured I would ask you lovely folks with more experience. I cannot tell which, but it looks maybe like a Deltoptychius or Deltodus to my eye? It's about 11mm in length. Good chance I'm wrong too, and it maybe not even he ID-able! Anyways, I appreciate opinions as always. -JG

Hi there, last fossil hunting trip I went on a week or so ago I found some nice fossils and than this. I was hunting some Burlington limestone/ chert that day. Not exactly sure what this is, a possible bryozoan encursting part of a brachiopod valve? I find a lot of pieces of brachiopod valves in the crinoidal layers, where this was laying so that would be my guess. Hopefully it shows, but the entire top side is covered in tiny pits. Thanks for the help, Jackson. I know this was collected from the Burlingtong Limestone. Heres an Azygocrinus rotundus I found about a foot away from the original posted ID piece for formation reference.

Greetings, all! I am currently writing a thesis involving fossils from the Burlington Limestone near its type section along the Illinois/Iowa border. To demonstrate the diversity of the crinoidal remains from the limestone (over 400 species have been described from the Burlington alone!), I am looking for photographs of articulated crinoids. Do any of you have any that you would like to let me include in my thesis? If possible, I would like high-res images of crinoids identified to genus or species with a scale bar/ruler present in the image as well as the collection/locality info. I can't guarantee that I will use every image posted, but if I use your image, then I will acknowledge you in my acknowledgements and give you credit for the image. Thank you for your time & assistance! -Elasmohunter

Here is another Mississippian shark tooth that I need some ID help with. I am still waiting for a bit of information from the seller but I am pretty sure this is a Burlington Limestone tooth from the Biggsville Quarry, IL. I had asked the seller if he had any Venustodus teeth and he sent me a few pictures of this one. It looks similar to other venustodus teeth I saw as I researched this but it looks a little different from others that had the same ID. It certainly seems to be a really nice tooth and one the kids would like learning about ! My gut says this is probably what I am looking for and the sellers ID is correct. I do not fully trust my gut with Mississippian shark teeth though lol So I thought it best to put this to the forum and see what my fellow TFF members think. Any thoughts on this one ??
