Late cretaceous nodule horn armor spike?

[MedicineHat]

Good morning folks,

I was sorting through a box of unknown fragments from surface collecting this summer. I inspected more closely this piece that looks like a spike. Not quite symmetrical. Looks like designed as potentially a partially lateral nodule or armor spike. I was referring to some past discussions on cerotopsian frill material and am curious if this may even be a frill spike?!? 

Any help would be appreciated. Thanks everyone.

The vascular grooves would make me lean toward a fragment of Ceratopsian frill.  Preservation not the best for me to say much more

This is a weird one.  I am not comfy saying one or the other.  It seems to have external bone surface on many surfaces including the edges.  Hmmm.....

Hmmm do you make anything out of the tapered "spike"? I'll take some additional photos. Perhaps I can get you more information. Thanks!

Any ideas? Am I on the right track maybe? Pr is this possibly just a chunk of weathered bone?
