Found on beach in hebrides. Heave jaw connections, small eye hole.
Is it a gannet?
No interactions present.
Gannets, and all other UK birds have relatively large eye sockets which occupy a large portion of the skull (and this looks too big anyway).
Arklooker is probably on the right track with his suggestion of a young porpoise or dolphin.
