In order to get a Crainados you need to get a Skull Fossil. The Skull Fossil is exclusive to Pokémon Diamond version.
You go underground and you can have chance to find the skull fossil and that will be craniados and the shield fossil (or something) for sheildon. But you can only get sheildon on pearl and craniados on diamond. _ _ _ _ _ _ _ _ On Pokemon Platinum you can get both.
after you get to goldenrod city go north to where is a place where you can choose to go to the pokleathon or the the park so choose the park and in the grass a weedle should come up sooner or later
Craniados

Dig underground for a cranidos fossil (skull fossil). After you have obtained one, take it to the Oreburg mining museum and have the guy behind the counter revive it. ~Sherry
Once you have the Cave Explorer kit, go underground and start mining until you find a Skull Fossil. Bring the fossil to the museum in Oreburgh City for defossilization.
You can't just go 'Find' Rampardos. You have to go in the underground (it doesn't matter if there is no one else there) and just tap the screen until you see sparkles on the screen and go up to it and hit the 'A' button. Then you dig in the wall and it tells you how many things there are in that spot in the wall. Just keep digging around until you find a Skull Fossil. There are other ones, a Skull Fossil gets you Craniados, the Root Fossil gives you Lileep, and the Claw Fossil gives you Anorith. When you find the fossil you want, (DON'T forget to put the fossil in your bag) go to Oreburgh city and go into the Mining Museum and talk to the man in the white coat at the desk. Do what he says. And then just level up Craniados. I have a Rampardos, he's awesome ;D
you get crandios by going under groud and dig for stuff but it takes a while becauses you might just shures for a while but then you start getting fossils and crandos is a fossil when you get the fossil you take it to the fossil guy that is in the mining musum and he will ask for the fossil and then you say yes and then go out side and then come back in make sure you have an empy slot in your party.
Talk to the digger dude in Eterna City, then go outside and use what he gives you, and then press a near the flashing dots. Then to revive the fossils go to Oreburgh City, Enter the rightmost building, talk to the guy on the counter, exit the building, re-enter the building, talk to the guy again and you either get a Craniados or a Shieldon.
