Hello, I recently found several concentrations of large animal bones above a small creek in central Oklahoma. There are at least four different clusterings of bones, all within about 50-100 yards of the creek length, and each spot contains what appears to be bones from multiple large mammals (cow size) ranging from leg bones to ribs to vertebrae to partial skulls and jaws. None of the bones appear to be particularly recent, and some are pretty degraded (skulls that are easy to break apart, cracked teeth). This location is also along the Chisholm Trail that ran N-S through Oklahoma in the mid-late 1800s. I haven't found any tools or weapons of any kind in the area, and haven't noticed any obvious markings on bones that might indicate butchering, hunting, etc. One skull recovered so far (not included in the pics below) has been confidently ID'd as an elk based on the presence of two lacrimal ducts in the front of the eye orbits. I was wondering if anyone is able to give an ID on any of the additional bones below with some level of confidence. I hope it is okay to include all of these pics in a single post (apologies if not and I can repost individually). Here is the most intact skull I have found, it is 24 cm across at its widest point: Here are lower jaw bones recovered so far. From what I have read online, it seems like the orientation of the mandibular notch is more like a cow than a bison, but the M3 teeth seem to be on the large side for a cow (upper 30s to a little over 40mm): Here are two closeups of the M3 tooth from the single jawbone in the picture above: A femur that is ca. 12.5-13cm wide at the condylar end: Last but not least, here are some pretty weathered upper teeth: Thanks again if anyone has the time and inclination to offer insight on any of these finds. Maybe they are just cow through and through, but I thought I would check just in case.

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

Hello all, My 9 year old son and i found this jaw bone on a beach in the most southwestern part of the Netherlands, the beach is known for fossilized black shark and ray fish tooth findings. And in the same area my Father found a piece of likely a Mammoth or other Mastodon tooth. (we may post pictures of this later). When we found it on the beach the teeth and bone were completely black, but it has brightened since, and after 2 months both are now a sandy beige/brown color. We first thought it was from a large cat like animal, but it has at least 5 molars (possibly it had more where the bone is broken) and in pictures of cat jaws i see only 3. The teeth are rather sharp. At the thin end of the empty space there is another broken part, which suggests it held a canine. The piece of jaw is 9.5 cm or 3.75 inch long. If anyone knows what animal bone this is my son will be very happy, as it's his dream to one day become an archeologist. Thanks

I found this in a creek leading to Grove Lake in Antelope county NE (near Ashfall fossil beds) I've found a lot of bone fragments and teeth there before, but this find was particularly interesting. Anyone know what type of rodent it is from and if it is from the same time period as the many mammal fossils at ashfalls?
