garyc Posted September 3, 2021 Share Posted September 3, 2021 (edited) Hello all! The Brazos has finally started coming down and I was able to get out for a short trip today. I think this is a sloth tooth, but I’m looking for confirmation from the experts. The picture of a paramylodon mandible I’m comparing to is from Kocsis’ Vertebrate Fossils: A Neophyte’s Guide. @Harry Pristis @fossilus @Lorne Ledger Edited September 3, 2021 by garyc 1 Link to comment Share on other sites More sharing options...
fossilus Posted September 3, 2021 Share Posted September 3, 2021 Looks right to me, but the Florida guys have probably seen more of these than I. I've only had a few sloth teeth. By the way, how long is it? Link to comment Share on other sites More sharing options...
Harry Pristis Posted September 3, 2021 Share Posted September 3, 2021 This looks to me like a section of deer antler. 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...

It is 1 inch wide Link to comment Share on other sites More sharing options...

JohnJ Posted September 3, 2021 Share Posted September 3, 2021 The larger end is out of focus. Maybe it looks diagnostic in hand, but it looks like a proximal rib fragment. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

Rockwood Posted September 3, 2021 Share Posted September 3, 2021 Wow ! That was a ride. The texture sure plays a tooth tune. I don't see an antler at all. I wouldn't "rib" anyone about that. Mammoth tooth fragment, maybe. I could see weathering doing that. Link to comment Share on other sites More sharing options...

val horn Posted September 3, 2021 Share Posted September 3, 2021 it looks like sloth to me, but I am no expert. Dr Huber is my favorite expert can you show it to him U of Florida? 1 Link to comment Share on other sites More sharing options...

Harry Pristis Posted September 3, 2021 Share Posted September 3, 2021 Please observe that the mystery object has cortex bone, something elephantoid tooth roots don't have. Nor do sloth teeth. But, deer antlers do have cortex bone. 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...
darrow Posted September 3, 2021 Share Posted September 3, 2021 The crossection exposed on the larger flat end remonds me of tooth dentin but it's hard to tell without having the piece in hand. I like the idea of a tooth root but I'm thinking more from a mastadon... 2 Link to comment Share on other sites More sharing options...
val horn Posted September 4, 2021 Share Posted September 4, 2021 I have never had a chance to look at the internal structure of a mammoth root but most tooth roots have a pulp chamber that is more open near the crown of the tooth and at its most narrow at its apex in the jaw. Therefore the very solid structure at its widest point is not what i expect in a tooth root. 1 1 Link to comment Share on other sites More sharing options...

Lorne Ledger Posted September 4, 2021 Share Posted September 4, 2021 Sorry but I am not seeing a tooth. Sloth teeth do not have longitudinal striations - they are horizontal if any at all. I am leaning towards deer antler fragment also. I will admit the interior structure and material looks tooth-like in cross section, but the shape of that encasing it just doesn't ring tooth at all.

JohnJ Posted September 5, 2021 Share Posted September 5, 2021 @garyc Much better images. I'm more convinced than ever, it is a probiscidean tooth root. 2 hours ago, garyc said: Here are a couple of pics with some sun light on it 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
