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!
