Hello everyone, even though I haven't reached 35 fossils in my collection like I hoped for this year, I still managed to close 2023 with my 34th fossil! The one I'm going to show you today is, in fact, this 34th fossil, which is also the first mammal fossil I've ever owned Species: Merycoidodon sp. (Leidy, 1848) Size: ~3.0 cm long Age: 34-23 mya (Oligocene, stage indet.) Origin: South Dakota's Badlands (USA) About this fossil: a partial lower jaw of this genus, with four nicely preserved teeth. I personally like how, in this specimen, the matrix is still present, which helps to keep the two parts together and just makes the fossil look nicer

I figured this was probably a long shot but thought I would check anyway. Is there anything distinctive about this tooth that would help narrow it down? miocene North Central Nebraska.

So I purchased 19 assorted Miocene-aged teeth from (according to the American seller) China a few years ago. The seller had given most of them a vague label (which I've labelled the pics with) - but wasn't able to get more specific. Could anyone help me narrow down which species they might be? Are there resources people are aware of that could help point me in the direction of being able to ID these teeth? Or is it very unlikely I'll get any definitive ID on these and I'll just have to accept a broad family-level description of what they are? I attached an extra picture of a giraffid tooth from the same collection - I reached out to a Chinese expert on miocene teeth from china and he believes "that it's a lower right canine and that it might belong to Palaeotragus or Palaeotragus-sized giraffid based on size". I thought FF members might find some interest in that.

This unknown partial jaw and molars came from a box of rocks at a garage sale in Minnesota. Scale is metric. My SWAG is a smaller sized Oreodont?

I would like to ask the experts on this forum for some help in identifying this jaw fragment. It contains two complete teeth (molars?). It is from a deposit west of Cuba, New Mexico, and is, as you can see, pretty small. The teeth are complete and look like they belong to an adult animal. They are not very worn. Any and all help will be greatly appreciated!

I had a good day and then in the last 30 minutes found a bone that I did not recognize. That makes it a great day. I do recognize this as a toe bone. and it is very likely to be a medial phalanx of an artiodactyl. BUT... At slightly less than 36 mm long, it is very unusual. The 1st photo was staring at me out of the sieve, and I was pretty positive that I had not seen the like previously. In searching for a Medial Phalanx, I found this one in @Foshunter Gallary Very similar but too big... I am looking for 1.5 inch ,not 2.5 inch in length. But I have found Hemiauchenia gracilis fossils at this sight !!!! Went to the UF collections database, and found the direct equivalent of my 1st photo !!! and closer to the same size, but definitely not similar... That 1st photo is very unusual, I can only hope a TFF member has seen it before.

I do not always attend my fossil club meeting, but made an exception last night. @minnbuckeye had generously donated some fossils for the upcoming club Auction (Thanks Mike) at the March Meeting and I was delivering said donations to the Auctioneer. Also we had a cold front coming in today , so I was out hunting yesterday. Found a couple of 100s small shark teeth, 4-5 turtle spurs a couple of mammoth fragments and some random bones, not much else. After hunting , grabbed burgers & fries at McDs , arrived to the club meeting an hour early. I also had a ziplok of fossils from my previous time out, which had some excellent fossils in it... like a mostly complete whale cookie..* (see below) I went back to my tailgate and was sorting fossils between a few I wanted and the rest to the prize table for tonight's raffle. A car pulled up next to me , lo and behold, it was Richard Hulbert, tonight's speaker on the Florida Fossil Permit and maybe an update on the Montbrook dig (https://www.floridamuseum.ufl.edu/montbrook/) which he leads.... I could not have been more pleased... Richard started to identify those random bones left and right... This one was heading for the donation pile until Richard said, "Artiodactyl, ankle bone, maybe bison, complete...." That is more that enough to track down one of @Harry Pristis outstanding identification photos (THANKS Harry ) and that definitely reduced the possibly IDs for this fossil to.... wither Bison or modern cow. If Harry has a right side ectocuneiform, this one is also... My "feeling" is that this one is hard fossilized, but as I have seen previously , size may be a differentiator. So Harry, if you see this thread, let me know if you agree with "right" and have any reason to believe more likely Bos than Bison.. Whale Cookie !!! (I actually think of them as Oreos, but they do not have that chocolate taste...
