These images show a c7 cervical vertebrae that probably belonged to a horse.
It was not excavated directly from the Stainton gravel beds, but could well have been washed from them.
You can tell it is a cervical vertebrae because of the para vertebral foramen on each side of the centrum. But it also has a facet for the head of the first rib. The only cerv vert with a rib facet is the 7th.I receive a lot of welcome advice from very experienced Friends from the United States.
