The topology of your skull is bad, there are vertices overlaying and inner faces, f you select some external vertices in Edit mode then press H to hide them and see what happens inside you will see it by yourself. Boolean doesn't work with overlaying vertices and inner faces, and I don't know if there's a quick way to fix the problem as there are a lot of vertices.
