Plesiosaur

Here are three views of a plesiosaur vertebra, almost certainly from the Kimmeridge Clay. The neural arch on top of the vertebra (central image) is largely broken off, while the canal in which the spinal chord once ran can clearly be seen in the left-hand image. The holes and pits in the right-hand image (the underside) are where blood vessels ran into the bone.
