Texas creek find. Bone ID?

[Robin Bradbery]

On a recent road trip we were given land owner permission to hunt the portion of Brushy Creek that crossed his property. We found lots of small pieces of pet wood and a few devils toenails but also a badly broken piece of bone. I was wondering if anyone could ID what it might be. It looks very old but isn't petrified.

Might be part of a sacrum.

Looks like part of a sacrum to me as well

That's what I think too. Can't think of another bone works foramen (hole) like that.

 

Heres a cow sacrum to compare with.

How do you know that it's not petrified?

The bone material has not been replaced with rock.

It could be Pleistocene sub-fossil bone. Much of the Late Pleistocene stuff I see is not fully mineralized.
