Please help identify this bone.

A picture would make the job much easier.

How do I add the pictures I have?

If you have the pictures stored on flickr, TinyPic, Picasa, etc you simply type the URL here.

It looks like a horse bone to me.

Perfect. Welcome to fluther.

You probably just got the correct ID from @KatetheGreat.

Some sort of bovine species?

If you look up the history of the North Sulphur River there has been fossils and bones found there form many years.

@digthis: Do you have a large university nearby with a paleontology or cultural anthropology or forensic medicine department? If the area has a lot of fossils, there must be experts in identifying the bones.

It looks like a femur or upper hind leg bone because of the rounded shiny knob at one end which would fit in the hip socket. I don’t know what animal.

This is so cool! Would you consider getting the bone dated? Even if the horse bone turned out to be only 50–100 years it would still make a nice story. Wish I could find a fossil…

@digthis If you collected that bone from public land and it is in fact a fossil, you may have committed a crime. Don’t want to spoil your parade, but the penalties can be strict.
