Hello, I am currently in a skeletal articulation course studying under the bone man, Lee Post. We are currently reconstructing a skeleton of a young female beluga whale.

On of Lee’s dreams for his articulation guides, and published papers are to contain measurement references so folks can self determine what bones they may have or found. Our class is currently 3D imaging the bones and skeleton to provide free online reference, as well as 2D image catalog with accompanying measurements.

This bone you have here appears to be a lumbar vertebra. Definitely cetacean, but hard to tell the size in the perspective of the images.

If you provide some measurements I can share them in my class and maybe we can identify for you :)
