What is "bathyspondylus"

Bathyspondylus is an extinct genus of plesiosaur. It was first described in 1982 from a specimen originally found in 1774, now housed at the Devizes Museum. Because it is known only from its fossil vertebrae (and so few of those have been recovered), paleontologists are not entirely sure of the taxonomy of Bathyspondylus; the family it belongs to is not currently known.

The type, and only known, species of Bathyspondylus is Bathyspondylus swindoniensis, which was described from the same material as its genus.
