Back at it again with some more specimens I hope to pin down an ID for. These are also from the Adams Branch Limestone/Winchell Fm of the Canyon Group. My method of slowly scouring through every stone around me paid off when I found these beauties. Finding a nice crinoid crown was a big goal of mine coming into the trip that I was pretty sure I wouldn't fulfill. It feels good to come away with so much more than I expected! We'll call them crowns 1, 2, and 3 from left to right in the images below: Crown 1 was super exciting for me when I initially came across it, but Melvin's enthusiasm amped me up even more. Although it's compressed, the "bulb" (idk the correct terms) is fairly complete with all of the plates and even some little spines protruding off of it. There are the beginnings of arms springing out as well as the first segment of the circular stem coming out the bottom. The plates for this guy are very bumpy. I've come to the tentative ID of Ethelocrinus magister, but I do not have much familiarity with crinoids so please, please correct me if I am mistaken. Once I pin an ID, I plan on making my debut in the find of the month contest! Crown 3 is only the very bottom, but has a similar bumpiness so I think it's the same species. Here are some more angles of crown 1: Crown 2's preservation is worse and I am unable to tell the original texture of the plates. I think it's smooth, from what I can see, so I've arrived to the ID of Delocrinus inflexus, though I realize a solid ID may be impossible. It's not very complete, but it shows some arms and some of the crown so I think it's still pretty neat. Here are some additional pics: The underside doesn't show much: To help inform y'all more, here is a pic of the two types of crinoid plates I found that day. Many bumpy ones and the occasional smooth kind: Thanks for reading

Hello all, This is my first post, looking for a little help? I am interested in buying this mosasaur jaw but i am unsure if it is real? (I have attached some screenshots, I have made sure they don't mention ad name or seller details) I have a few little red flags. Looking deeper into the photos, I cannot tell if there is matrix between the crown and root. Thanks in advance for any help

Had some productive hunting and found this in a gravel bar. I'm hoping I've found my first gomphothere or mastodon tooth! Or at least a part of one. I've looked at several threads about differentiating them, but I still had a hard time identifying this for certain. Am I headed in the right direction or could it be something else? It does look smaller than I would have expected. Any help is greatly appreciated.
