Does anyone know what this is?  I found this while beach walking in the San Diego-area.  It's about 3" across.

Since no one else is available I'm going to take a guess at dolphin vert.

Nice vertebrae. Is it a fossil, did it pass a burn test?

Hi all- thanks for the quick replies.  I'm a novice so a few question here:

 

1) how do you determine if it's recent vs. not / a fossil?

2) what part should I 'burn' to test if it's indeed a fossil?

3) how did you deduce it's a dolphin or. mammal (or something else)?

Modern dolphin or whale vert, to my eyes.  If you try burning a modern bone, it will smell nasty. Mineralized bone won't smell.
