Still_human Posted March 12, 2020 Share Posted March 12, 2020 There’s absolutely 0 information about this 14” bone at all, as it’s from an estate sale. Does anyone somehow have ANY ideas what it might possibly be, just by visual clues? Mesozoic? there’s a rattle when it’s shaken, which might somehow help age it, based on mineralization, I dunno(if that’s not at all likely for something that’s been mineralized for over 65mil years, as opposed to less than a million?). I love it because it is absolutely COVERED in predation and scavenging marks on both ends, and more, but I wouldn’t really want it if it was a post Mesozoic mammal. Any thoughts anyone might have would be greatly appreciated! Link to comment Share on other sites More sharing options...
caldigger Posted March 12, 2020 Share Posted March 12, 2020 Your predation marks look more like acidic root scaring. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted March 13, 2020 Share Posted March 13, 2020 I would very much doubt it’s from the mesozoic. I’d conduct a burn test as to be sure it’s not modern.

JohnJ Posted March 13, 2020 Share Posted March 13, 2020 Looks like a modern radius...maybe equine, with a lot of rodent gnawing. 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

Oh wow, I should do some research on that, I always forget about, and have no idea what to look for. We’re you thinking all these marks are likely roots, or just the major indentations? The edges look so much like bones I’ve seen chewed on, the edges couldn’t actually be root acid, could they? Link to comment Share on other sites More sharing options...

That’s what I was wondering:/ it just looks off to me, but it does still look mineralized to me too, but I definitely wouldn’t trust my own judgement for that! i was wondering if that small thinner part branching off, that appears to have its end gnawed off, was something that might stand out to help identify it.

Again, I would compare it to a horse radius. 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
caldigger Posted March 13, 2020 Share Posted March 13, 2020 You might have some gnaw marks on there too. I couldn't see the grooved areas until you blew it up. Link to comment Share on other sites More sharing options...
Still_human Posted April 9, 2020 Author Share Posted April 9, 2020 I passed on it. Unless i had at LEAST just reason to BELIEVE it was mesozoic or before, or an early whale/whale ancestor I definitely wouldn’t get it. Thank you all for your help, yet again!!!
