MegaceropsAreCool Posted March 9 Share Posted March 9 It is a Toe Bone found in the Brule Formation Custer County, South Dakota. It’s dated to be from 35-30 million years old. The Bone is small, only 1.6 centimeters. I’m not sure what species it is, if anyone possibly knows or know a species it can’t be it would help a lot.

jpc Posted March 9 Share Posted March 9 (edited) why do you call it Bathornis? It looks like an oreodont or a camel toe bone from here. Bathornis is a bird and is extremely rare. Edited March 9 by jpc 1 Link to comment Share on other sites More sharing options...
MegaceropsAreCool Posted March 9 Author Share Posted March 9 it’s definitely not camel or oredont, it would have to be much bigger Link to comment Share on other sites More sharing options...
Randyw Posted March 9 Share Posted March 9 Actually it wouldn't. Some oreodonts are small. But that very much resembles oreodont toe bone to me. And at 1.6 cm would be about right for a medium to sm oreodont. 1 Link to comment Share on other sites More sharing options...
MegaceropsAreCool Posted March 9 Author Share Posted March 9 I’m looking through an osteology book, and i also got this reference for cariama just to show this is a bird Link to comment Share on other sites More sharing options...
jpc Posted March 9 Share Posted March 9 It would be nice to see the side view of both the cariama and some mammal toe bones to really compare. Somewhere here I have a nice camel foot that when I find a minute I can try to fond and photograph it. But right now I am stalling form doing my taxes....

Ask and you shall recieve. Here is a full sized culbertsonia oreodont toe bone I’m still cleaning up from a bone block with skull i been working on. It’s 1.9 cm long. I’ve got culbertsonia skulls that are a quarter the size of the animal this bone belonged to. Sespia natida and leptauchenia oreodonts are even smaller then that… i dont have a picture or sample to hand at the minute but the sespia, leptauchenia, and some of the smaller oreodonts the bone has a similar shape but is thinner and more gracile I suppose the word would be… I need to find it but I’ve got one that looks very similar to that one.

Randyw Posted March 10 Share Posted March 10 (edited) Found it! This is an oreodont toe also. It’s 1.7 cm long. I prepped this out of a block with some oreodont rib and spine pieces Edited March 10 by Randyw Link to comment Share on other sites More sharing options...
MegaceropsAreCool Posted March 10 Author Share Posted March 10 can you describe the texture like what it feels like Link to comment Share on other sites More sharing options...
MegaceropsAreCool Posted March 10 Author Share Posted March 10 also how tall is the toe bone (height) Link to comment Share on other sites More sharing options...
jpc Posted March 11 Share Posted March 11 texture? texture is irrelevant. or is it...? on Randy's first toe picture, see that notch on the extreme right edge? I don't think birds (or dinosaurs) have that. Yours has it too. Mammal. 1 Link to comment Share on other sites More sharing options...
