Flat dino bone with 2 holes and weird internal structure

Found while digging in the badlands of Montana in Glendive, in the very corner of the Hell Creek formation we found this single flat piece. At first I only noticed the one hole in the front, but upon closer inspection I discovered a partial second hole above the first, and one side has a structure visible inside the bone. Just wondering if anyone has any clue what it could be! Thanks for any input in advance.

Looks like a foramen. A vessel passage.

Missed it by seven minutes. Quite a colorful bone fragment.

Fossil hunting is easy -- they don't run away when you shoot at them!

Ok, so I used to work in the dental field and my first thought was it looked like the mental foramen, but this is obviously not a jaw and I am not a doctor so I wasn't sure. What other parts of the body could this be from? Any ideas? Thanks!

If it's part of a five-foot-long skull . . .       I haven't checked to see if any other dino bones had foramina.

A lot of big animals roamed Hell Creak. Could be a fragment of any one of many bones from many animals.
