Ah well this ones a fake of course but honestly that's what G calls it--- largely because the thin hollow (attached) skull is often smashed in or dented in just due to wear. Finding one intact is rare, I have one of each example... Obviously other patterns can be "smashed" due to the construction of course, I know I have at least one other like that- but I suppose that this pattern in particular is much more often found smushed in to borrow from Gaspares description, than the others
