The aperture appears to be surrounded by a raised rim with regular segmentation of that rim, and this reminds me of the coossified scleral ossicles in ankylosaurs and ceratopsians. The apperture is less than an inach across, which makes me wonder if it really is an orbit, but from the appearance and the rough texture around it to the smooth region in the upper left, I am guessing this is an ankylosaurian (nodosaurid?) skull, rotated so that the maxillary margin is facing to the upper left. It's just a casual guess.
