Unknown osteoderm from the Peace River

Recommended Posts

PaleoNoel

Hey everyone, I found this fossil last February on the Peace River, I believe I posted it with a bunch of my other finds from that trip a while ago and the ID came up inconclusive. I was hoping the folks on the forum could help me out with this one again. It's about 3.5 cm in diameter and I first thought it belonged to a glypodont but I'm not so sure.

Hi There, glyptodont osteoderms are quite robust.  I'd like to also toss out the possibility of something I see often here in Georgia. Similar fauna. I get quite a few bony fish skull elements.  They are quite fragile all being considered and have a similar texture when worn.

 

Cheers,

Brett

 

PS. I'll pull a few out for comparison. I usually don't keep the majority of them. Here are the few I have left.

Thanks, after seeing more glypodont osteoderms over the past year I've eliminated it too.

Here is a Lee Creek example from elasmo.com:

Sturgeon. Pls see my other response above.  They are extremely common in the Pliocene sediments of the Yorktown Fm of Lee Creek

Thanks .... they are not uncommon here in bits and pieces. I appreciate the fish ID. Lee Creek just keeps giving.

 

Cheers,

Brett

Thanks guys! How often are these found in the peace river? I don't think I've seen them in anyone's trip reports on here before.

What does the other side look like? It looks like a worn piece of turtle shell to me. Post for comparison.

Also turtle shell frags from Apollo Beach that look similar to yours.
