The temporal is the easiest to recognise, even fragmented. Occipital is usually also not bad. It’s the inside of the skull that was the hardest for me, especially if the fragmentation is significant.

…so I can’t possibly forget to commit all the cranial bones to memory by next Wednesday’s exam. Of course, this is only a handful.
