Whale rib fragment or something else?

[Bradley Flynn]

Found this on a beach with some shark teeth and other bone fragments. Most of the bone around there is very worn and tumbled, making it impossible to ID. This piece however has some interesting features and could possibly be identifiable. I'm thinking its a piece of the top end of a whale rib? Anybody recognise this as something else, large terrestrial mammal maybe? Thanks

So I'm thinking that this fossil could be a horn core, from what I am unsure. The wrinkles on the surface seem to match with the bone structure of horn core, the thickness of the bone walls, the ridge on the side seem to match some large antelope species, the fossil is tapered with a slight twist. What you guys think? 

Also realised that I have a skull element with the base of the horn core attached while researching the fossil in question.
