Hi,

I purchased this bone and was told it washed up on the Carolina shore. Could you please tell me what it is?
Thanks!

Based mainly on the bone's curvature, large size and thin, plate-like proportions, it looks like a neck (or cervical) vertebra from some sort of whale. The preserved part is the body (or centrum) of the vertebra, but the bases of the snapped-off arches that would protect the spinal cord and vertebral arteries are also visible.

In some whales the neck vertebrae are fused together, but your bone clearly comes from a species in which they remain separate. I don't know which specific whales belong on this list, however, so I can't narrow the identification down any further. One of my colleagues on the site may be able to help with this.
