Judith River Ceratopsian Horn?

[Squirrelman91]

I have this chunk of bone from the Judith River formation of Hill County, Montana, and I was wondering if this is a partial horn? It was found with some other small skull fragments, but this is the main piece. Does anybody more familiar with ceratopsian horns have any insight? It is 5.3 inches in length (I forgot a ruler picture, my apologies). Thanks in advance!

Following along! What do u think @Troodon

Not sure.   It's very cylindrical not tapered typical of horns but it's only a fragment.   The surface appear to have some vascular grooves typical of a horn, see photos, but also lots of holes are present not typical.  So its possible but not certain.

 

Photos are from the Hell Creek Fm.
