I found this last year, just now got to it. While I put fish fossil in the title, I don’t really have any ideas on this one. Any ideas would be greatly appreciated! Pleistocene Glacial material of eastern Kansas, USA. Measures roughly 21 mm long. Possibly vertebrae?

Here are a few molars that I’m stumped on. They were all found In NE corner of Kansas in some Permian (edit: not Permian) glacial drift material. Molar #1: Going through @Harry Pristis’s album, to me this one resembles Tapir, but I am doubtful Molar #2 I have no ideas on this one, initially guessed peccary but I think that is incorrect Molar #3 This one has some of the root, although some of the top surface has been broken Thank you to everyone in advance! I try to ID our fossils myself, but these I can’t seem to figure these out. Have a great day everyone

Found these on different sand banks along the Kansas (Kaw) River east of Lawrence. They are definitely fossils, and I believe they are some sort of tooth or molar, but I am no expert. Any ideas or positive ids appreciated! ps: this is my first post measured in metric in photos

I found this maxilla piece on the Kansas River today. I'm thinking it's some sort of pig ancestor, and hoping it's not just an old domestic pig's. But it seems mineralized to me. Also, the teeth are pretty worn so it's hard for me to ID them. I saw this topic And thought it's too difficult for me to ID based on the worn teeth. But maybe someone else here can help? Please let me know if more photos would be of use as well. Thanks in advance.

Hello. A quick introduction. I have been walking the kaw for decades and have amassed a collection of artifacts and bones. What I have not amassed is the ID skills, especially between bison and cow. There are hints in the area I hunt that at one time, long ago, a butchery that either has eroded off the bank or they discarded items into the river. Guessing it was near Grantville, Kansas. So it can be a bit confusing for me between that and how the river deposits in general can age at different rates depending on where they’ve been hiding out. I really look forward to getting to know the items I have and some of you! My goal is to start pairing down my collection. I want to be accurate and honest about what I am presenting and not just going on Google guessing. Thanks for any help and if there are things I can do to improve my postings in the future please feel free to push this newb around and set me straight. Thank you. and now, the first bone. Am I correct in thinking this is a tibia? Is there a sure way to know if it’s bison or cow?

So, springs a happenin and I had two opportunities to float the Kaw river, a shallow, shifting sand bar river meandering through central Kansas to western Missouri where it connects to the Missouri river. My first trip a couple weeks ago focused on the macro pleistocene fossils, a bison ulna, astralagus, phalanges, ribs, metatarsals, busted scapula, calcaneous, and various vertebral bodies , some chert flakes from early hominids, pieces of fossil wood, etc. The second trip focused more on micro fossils - I had flipped my kayak in the river on the first trip, and though cold and soaking with waders filled, I recovered everything. The second trip I prepared a little better- I needed a 5 gallon bucket, my 5 sieves, a smaller bucket, and my hiking stick. I needed to figure out how to get to the sandbars, so I tethered the sieves in an inner tube, and sealed the bucket and tethered that as well- worked perfect as there was little drag on the whole train!. I always check the CFS and never go when it is above 5,000, and almost always between 2-3,000 and this was no different, with warm weather and not one person in site! I found portions of ribs ( very common), this bison tooth, a fossil turtle scute, stalagtite, and this corner notch spear point. Most people would call it an arrowhead, but actual arrowheads are far smaller-this was hafted and likely placed on an atlatl, or throwing spear. Numerous chert flakes from working pieces, and then, after sifting several pounds of sand, I found these microfossils. The first reminds me of a cowrie shell but looks more like a piece of coral? The second, and most common fossils I found were these very small, colorful corals? and then this interesting piece i have simply no idea.....even if it is a fossil? there are three ridges on one side-thoughts? then a worn crinoid piece?.....I am assuming ...I haven't even gone through 10% of what I collected!. And I am a little in awe of the color in the sand .. all in all a successful trip, made even better by my new macroscope, camera, HDMI screen, etc .... Its just nice to get out, get fossil hunting and fishing!!!!. Any help identifying these appreciated as always!!!..... Bone 1705181703_kawrivermicrofossils.pptx
