Looking to identify possible Mammalian Fossil

[natecfields]

We found this heavy fossilized bone at a river bed today in the Duck River of Middle Tennessee. Thank you all for any who can help us find some possible leads as to what this may have come from. Found by my 7 year daughter Taliah.

Aw, what a cutie!

 

just a thought: may not want to post her photo and name on a website

With it being incomplete, you might not get a solid ID.  Possibly a bison tibia?

piece of a leg bone is about as detailed as you can get, I think.

Welcome both of you to the forum.

You are a fortunate man to have a daughter interested in fossils... Here is how you make a good guess at this... 

Here is a fossilized Deer Tibia...

 

So , break of the end, the marrow hollowed out and split lengthwise.... This bone could be about 12-13 inches..

You have to evaluate ,, This bone length seems a little small in length and not robust in circumference...  SO , we might have to move up in mammal size to one larger ..

 

Here is a tibia for wolf... You likely had fossil wolves in Tennessee...

So just look at likely mammals in the last million years in tennessee,  Estimate the size by robustness and length and come up with a possibility.  Search  the internet with your daughter,

She will probably find one possibility she likes.

Wouldn't wolf tibia be a step down in size?

Yes, but I am not trying to be too accurate...

Here is an Equus tibia... 393 mm and far more robust than what is shown above.. So, If a deer tibia seems to narrow and not as robust , what mammals would exist in the Tennessee fossil record between deer and horse...
