horned sea monster washes ashore spain baffles officials

Perhaps it is a spinal column of a much larger creature, such as a whale.

that was my first thought too but then I had to think, "where are the ribs?" Because they aren't there but they should be attached. Maybe something happened and they were broken off of that part of the spines fallen away because of how decomposed it is, I don't know, I just know I'm not seeing a whale sized ribcage there. Also if they can tell the "horns" aren't horns then why cant they say what it is?

Scratch that. I'm thinking land animal that was cut up and thrown in the water.
