this is an unknown vertebrae found on the beach years ago in the Monterey, CA area. I always thought it was a marine animal but am unable to determine if it even is from the ocean... i need help identifying this unknown vertebrae please. bone is 5 inches by 3 inches.

If you look at lumbar vertebra from a seal then you notice that the transverse processes, the bits that stick out the sides, come off the main part of the bone much lower down and point downwards.
