1 Note the top of the eye socket is not fully formed.
This horse skull piece is from the lake bed deposits at Stainsby beck.
Many mammals have a small supra-orbital foramen just above the eye socket which communicates from the outside surface of the skull above the orbit to the interior of the orbital cavity. Sometimes this foramen fails to fully form, and is open to the edge of the orbital rim, as in your horse.
The explanation above is from Richard White a Palaeontologist from Tucson in the United States, a trusted friend and advisor.
