Meganeura Posted May 22, 2023 Share Posted May 22, 2023 So I found this today… I originally saw the hollow end and thought sloth tooth. But the side where the chewing surface would be is devoid of the enamel ring. However I’ve certainly seen sloth teeth that are worn down enough that the enamel is missing. However it looks like there’s enamel on the broken/hollow/supposed root end - a very thin layer though. The hollow end also has growth rings like a shark vertebra, and with the indent down the side, also points to vert. But it’s only on one side, not the other, which is smooth. That same indent also seems to rule out rib bone, as far as my experience with said rib bones go. So… anyone have any ideas? @Shellseeker @digit @Brandy Cole @Harry Pristis Broken/hollow end: “Chewing surface”: Sides: Growth rings: Enamel? 2 Fossils? I dig it.

Brandy Cole Posted May 23, 2023 Share Posted May 23, 2023 I initially thought it was part of a small, worn vert centrum, but the photo of 'rings' made me second guess that. Not sure what you have there! Link to comment Share on other sites More sharing options...

Not sure what you have there! Yeah I was thinking the same originally but I just… don’t know. It’s such a weird fossil! 1 Fossils? I dig it.

Brandy Cole Posted May 23, 2023 Share Posted May 23, 2023 Here are some pretty good comparison pictures that make me lean toward the sloth tooth camp. http://www.fossil-treasures-of-florida.com/sloth-tooth-sloth015.html 1 Link to comment Share on other sites More sharing options...

The problem is there’s no enamel band that I can see on the “chewing surface”, and the other end kinda-sorta may have a very thin enamel band? But I’m not sure… Fossils? I dig it.

Brandy Cole Posted May 23, 2023 Share Posted May 23, 2023 Shape looks similar, but yeah, the texture looks pretty rough by comparison. 1 1 Link to comment Share on other sites More sharing options...
Mahnmut Posted May 23, 2023 Share Posted May 23, 2023 (edited) I join the sloth tooth camp, attributing the rough texture to mechanical weathering.

Meganeura Posted May 23, 2023 Author Share Posted May 23, 2023 @PrehistoricFlorida Nate, I know you’ve found some funky sloth teeth - what’s your take on this? Fossils? I dig it. Link to comment Share on other sites More sharing options...

Many times it's a lot easier to say what something isn't, than what it is - it's definitely not a sloth tooth. As to what it is, I couldn't say definitively, appears to be a nondiagnostic shard of bone. 3 www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...

Bone was honestly my first guess - but the weird internal patterning and the notch threw me off. Fossils? I dig it. Link to comment Share on other sites More sharing options...
