snake vertebra

Anyone here recognize this snake vertebra? . . . Family would do. I am stumped.

This one does not fit Auffenberg's key in his 1963 paper on the fossil snakes of Florida. In the first place, this was a very large snake which doesn't seem to fit into the known Boinae of that paper (or of the state of knowledge in 2001). I suppose this could turn out to be a caudal vertebra of one of the known snakes, say Pseudoepicrates stanolseni . . . anyone know about caudal vertebrae?

The snake vertebra is from a site that is distinctly older (Early Hemingfordian) than Thomas Farm (Middle Hemingfordian), so anything is possible.

Any help would be appreciated.
