Calling all arborists. Need help identifying tree feature.

What could have caused this unusual feature in the bark of a mature post oak tree? Another view.
This is a 150+ year old post oak that is being studied for its potential to be an Indian trail marker tree. I am asking here about the specific bark feature. Our local arborist does not think it was caused by a cut branch. He thinks these features occur when something is embedded in the bark. Thank you!

Galls can also be caused by bacteria or fungi.
I'm not an arborist, but it seems like normally when bark grows around a wound, such as putting a nail in the tree, you see a visible callus that is smooth and rounded around the edge.
