garyc Posted October 30, 2019 Posted October 30, 2019 I’ve had this chunk of bone for a while and not been able to get an ID on it. It is from the Brazos River in SE. Texas, Pleistocene material. Any ideas? @Harry Pristis, @fossilus, @Shellseeker @jcbshark @Uncle Siphuncle @JohnJ

General bulkiness, and it kinda looks like there are worn out suture lines running down the middle. I can't tell you with confidence what animal it belonged to, but my best guess right now is bison skull 2 Max Derème "I feel an echo of the lightning each time I find a fossil.

Uncle Siphuncle Posted October 31, 2019 Posted October 31, 2019 WAG....tip of a mammoth jaw, tumbled? If not, I'm not getting a good vibe based on pics. 1 Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils."
Harry Pristis Posted October 31, 2019 Posted October 31, 2019 I agree with elephantoid skull. 3 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest
garyc Posted October 31, 2019 Author Posted October 31, 2019 Thanks for the replies! I also was thinking skull. I tried comparing it to a bison skull I have , but it didn’t seem right. Mammoth/mastodon seems more likely. 1
Uncle Siphuncle Posted October 31, 2019 Posted October 31, 2019 Regarding skull, I don't have the experience to know which sections/specific bones have honeycomb structure, and which ones appear more solid, like this one. But I'd guess that if a skull piece, this one would be either a section too thin to have honeycomb structure, or a part that bears enough load to require density. In other words, I'm curious which specific bone this might have been, when whole. Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils."
fossilus Posted October 31, 2019 Posted October 31, 2019 By chance could the smooth, concave side be part of the aveolus of a tusk? I may be way off as it's hard to ID with only photos.
garyc Posted October 31, 2019 Author Posted October 31, 2019 I just left town for a couple of days. I have another piece that I think matches @fossilusdescription of an alveolus.. I’ll post that here when I get back
garyc Posted November 2, 2019 Author Posted November 2, 2019 Here are some pics of a piece that I think could be an alveolus. Thoughts? @fossilus @Harry Pristis @Uncle Siphuncle
fossilus Posted November 2, 2019 Posted November 2, 2019 I agree the second looks like a part of an aveolus. Could the first be a juvenile and more proximal to the skull?
fossilus Posted November 12, 2019 Posted November 12, 2019 I was looking at some proboscidean skull elements and was wondering if your piece could be the forward portion of the jaws where the 2 side meet. I don't off hand remember what it's called.
garyc Posted November 13, 2019 Author Posted November 13, 2019 Ooh, you actually made me get out of bed to go look @fossilus! It’s close, and I can definitely see the resemblance, but even in hand I can’t say with 100% certainty. I even have a chunk of jaw that would be a match, but it has foramina where the piece in question does not

Just wondering out loud. I was angling toward chinny-chin-chin initially as well, hard to say on some pieces without them in hand. I have a cool juvie mammoth jaw found in NE TX with a cool point to its chin reminiscent of King Tut. It is a good comparison piece, noting that any degree of wear on a comparison piece would make this feature appear less prominent. If only the jaw still had a tooth in it... Grüße, Daniel A.

I believe that foramina presence and position would be fairly consistent within species. They allow nerves and blood vessels to pass through. But then again, it doesn’t matter what I believe. Maybe one of the experts can chime in on this
Uncle Siphuncle Posted November 14, 2019 Posted November 14, 2019 Chinny-chin-chin of yore. No tooth = raw deal. Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils."
garyc Posted November 14, 2019 Author Posted November 14, 2019 that last photo is pretty convincing. Although, mine doesn’t have the protuberance on the outside, like your “king tut chin”
