johnnyvaldez7.jv Posted April 21, 2023 Share Posted April 21, 2023 (edited) I found this large bone today that I think might be a bison leg bone? Could be bovid but aren't the rear bison leg bones not as robust as the front? Thought I read that somewhere. But I can't tell if it's a radius or a metacarpal bone. It's highly mineralized...very heavy and solid. River chewed it up pretty good tho. Didn't think it was horse because it just seemed too big compared to other horse bones I've found and I can't find any good pics online of the features in the third picture. Sorry didn't get to clean it up yet. Found plenty of Pleistocene mammals in that spot. Cows too. Lots of cows. This is 13.5 inches in length.

Harry Pristis Posted April 21, 2023 Share Posted April 21, 2023 It certainly resembles a horse radius . . . mule? donkey? proximal radius: 1 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
JohnJ Posted April 21, 2023 Share Posted April 21, 2023 2 hours ago, Harry Pristis said: It certainly resembles a horse radius Does the styloid process of the ulna seem too long for horse? The ulna fusion scar seems a bit long, too. @ClearLake 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
johnnyvaldez7.jv Posted April 21, 2023 Author Share Posted April 21, 2023 Here is an image I saw online of the distal view of a radius from a cow. Seems more like the 5th image from my post. Haven't compared bison but will. But it is heavily mineralized...wasn't there a thread where someone mentioned mineralization and cow bones and if they've been here that long? I'll have to check on that. Link to comment Share on other sites More sharing options...
Harry Pristis Posted April 21, 2023 Share Posted April 21, 2023 Yes, could be bovid -- that was my first inclination, but just couldn't make it fit in the moment. 3 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
JohnJ Posted April 21, 2023 Share Posted April 21, 2023 I think it ticks most of the bison characteristics in Harry's post. 1 2 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
ClearLake Posted April 21, 2023 Share Posted April 21, 2023 (edited) I looked at this briefly yesterday, then got distracted and never replied. I would agree with what has been said, it seems to fit bison most closely. The shape of the distal end was wrong for horse as I recall and at least in my specimen, the horse ulna is more solidly fused than is the case for bovine (but that is probably just an age thing) Compare the bison on the left in the photo below (from Olsen’s book) with @johnnyvaldez7.jv picture #5 and I think you will see that is the best match.
