Dig Underground
No, you can only find them. You can dig for them in Diamond and Pearl however.
I'm not sure exactly if you can get it in diamond..... But if you can, you have to dig it up underground
You can dig up fossils underground by using the Explorer Kit in the Key items pocket of your bag :)
at the mining museum you can swap your fossils (witch you can dig up underground )for Pokemon.
use your explorer kit then click on the screen then some shiny dots may come in sight go to them and dig in them and it may come skull fossils
You can only dig for the fossils in the mines.
If you do not yet have the digging kit, go to Eterna City and go into the house next to the poke-center and he willl give you a digging kit. Go underground and search the shiny areas on your radar and by tapping on the touch screen, and eventually you should find a skull fossil :) Warning: You can only find the skull fossil in Pokemon Diamond. In Pokemon Pearl you only find armor fossil
if you mean evolving stones you can go to the underground and dig for them. you can find many other things there too like fossils ect.. -Rg-
The same way you get a skull fossil on diamond, dig in the underground till you find one.
well, there are tons of items, the main items are spheres (those let you buy things), fossils (you can go to oreburg and turn those fossils into other pokemon), and many many more.
You dig for fossils where there is a brown X on the ground.
