  1. 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.

    Bison Bovid Conundrum (Needs ID)

    Ok I thought I had started to be able to ID bovine teeth and jaws and then this threw my off. This is from a post on Facebook - found in a cave in Kansas. I have posed here with he user's permission. Why is there a three-lobed molar in the middle of this lower jaw? In the past I had though the m3 for cow/bison was the only three lobed molar. But some searching online is telling me otherwise. Also the m3 here looks two-lobed. Can someone clarify?
  3. Hi, not too long ago I went to East Runton and Happisburgh in the hopes of finding some fossils, whilst the best time to go is winter, I was happy going in Summer. Apparently, fragmentary Mammoth molars are found commonly at Happisburgh during winter months. I found possibly two bits of mammal bones, possible fossils shells (one was in the clay cliff) and an orange belemnite. Is it possible to identify the bits of bone, or are they too small? Possible fossil shells Possible bits of bone. The top bit split when I picked it up, unfortunately the split bit then split, so that's just drying now after being glued. Orange belemnite

    Equus sp.

    Horse Teeth 'Modern' horse teeth are very hypsodont (high-crowned) to deal with wear caused by eating gritty and/or fibrous foods like grasses. A mature horse may have as many as 44 teeth, which include: 12 incisors (6 upper and 6 lower) Canine teeth are usually absent in female horses but may be present in males. Cheek teeth (4 premolars and 3 molars per side) have very complex enamel patterns. The first premolars (upper and lower) in horses (sometimes called the 'wolf teeth') are vestigial and often absent. Upper cheek teeth (premolars and molars) can be recognized by the relatively square shape (except for the second premolar and third molar) when viewing the occlusal (chewing) surface. Lower cheek teeth (premolars and molars) can be recognized by the relatively rectangular shape when viewing the occlusal (chewing) surface (except for the second premolar and third molar). Horse 'foot' bones 'Modern' horses are monodactyl (one-toed). The metapodials (hand and foot bones) are reduced to a single unit on each leg. There are three 'toe bones' - phalanges (singular is phalanx) on each foot...phalanx I, phalanx II and phalanx III. The third phalanx is the 'hoof core' Unfortunately, I have never collected an intact phalanx III so I have not pictured one here. The astragalus (ankle bone) is only present on the hind legs.

    Bison m3 Molars

    From the album: TEETH & JAWS

    Two Bison sp. third lower molars of different age. This is the last tooth to emerge at maturity. The younger individual had not worn its teeth much . . . tooth wear has not reached the diagnostic isolated stylid. The older individual has worn its teeth enough to engage the isolated stylid. Note that the tooth of the older individual retains some cementum. In life, all the bison cheek teeth were wrapped in cementum. Being the softest of the three types of tooth components (enamel, dentin, and cementum), this exterior 'wrapper' is often lost on a fossil.
