No, not bone. You can Google the reasons why. Mostly it seems to be they have no marrow. I'm trying to interest the Mutter Museum in my skull, preferably after my natural death, for their displays.
Humans are born with about 100 more bones that they end up with as adults, somewhere in the neighborhood of 300. It seems that a number of those bones fuse together to form single bones as maturation occurs. The count in your post leads one to believe that you're in your mid to late adolescence.
