Found this cool complete little bone while screening some gravel in a Summerville creek. Seems familiar but not enough to hazard a guess. Thanks for looking!

I don't claim it as an identification, but check out an image of a deer pelvis to see if it has any hints in it.

Thanks for the reply, I think it’s a complete bone tho.

It's not a complete bone, it would not be a complete pelvis just part of it.

Possible ischium of turtle or alligator...?
