The Skull Fossil is the fossil of Cranidos. And there is no definitive place for the Skull Fossil. Just so long as it's Diamond we're talking about, dig in to the wall for treasure when there's an opportunity, and at some point, you'll find a Skull Fossil.
Then put it in your Bag, go up, get to Oreburgh Museum and give it to the guy. Come back in about ten minutes, and he'll give you your Pokémon. You'll need a space in party though, because he won't transfer it straight to your PC, unfortunately.
Actually, the fossil that appears depends on an odd Factor. According to The Official Pokemon Guide, depending on the end number of your Trainer ID the Fossil that you find can be either one. An even number means you will only find armor fossils, while an odd number will mean you'll only get Skull Fossils, not both.
Also, the odds of finding other fossils (and those items that extend certain moves, that are found in the Underground) can be affected by the last digit of a Trainer's ID.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
