You can get all the fossils underground, except for shieldon or cranidos. You find shieldon if your ID is even and Cranidos is your ID is odd.

Underground
you need the skull fossil whic you can get underground
By digging underground, you may find Fossils. If you find a Skull Fossil, go to Oreburgh City and get in reincarnated at the museum.
To find Cranidos on Platinum, you have to dig underground for a skull fossil. Then go to Orburgh City and go to the museum. Talk to the Scientist and he will revive it into a level 20 Cranidos! -Hope this helps! :)
cranidos comes from the skull fossilwhiteless
after you get the explorer kit you go underground and dig in the walls. eventually you will find a fossil. take it to the mining museum oreburge and then walk outside then talk to the guy at the counter again and he will give you a cranidos.
You get a fossil from underground then you give it to the person in the museum to excavate a fossil. and you will either get a Sheildon or a Cranidos . P.S The museum is in Oreburgh City.
Must trade Cranidos appears in Diamond/Platinum (odd ID number) - Revive Skull Fossil
