look on the map until you find a split bit and one end will have a dead end go the dead end way
Wartortle is at vien forest and cranidos is being chased by it save the cranidos and it becomes your partner Pokemon
To find Cranidos in Pokemon Ranger: Shadows of Almia, you must unlock the 'Please Save Cranidos' quest. This is unlocked by clearing the fourth mission ('Destroy the Strange Machines') and opening the Partner Farm in Chicole Village. Accept the quest from the man near Vien Forest. Upon entering Vien Forest, follow the path North, turning to follow it West before you reach the bridge. At this point, you should see a Wartortle chasing a Cranidos and running away. Continue to head West until you come across a small path to the South. Go down this path and you should come across the Wartortle chasing the Cranidos. Capture both of these Pokemon in order to clear the quest and get Cranidos. Note that Cranidos will not appear anywhere in Almia, and it is solely dedicated to being your paetner Pokemon.
You can find Cranidos in Cerulean City where Misty is.
go under ground and dig (you can only get cranidos in dimond sorry :(
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.
Go under ground and find a cranidos fossealand evolve the cranidos into rampartos
I don't think it's possible to get a cranidos in Pearl.
You just take on a really easy quest from a dude in the forest. I forget when you can first take it on. Just save a Cranidos being chased by a Watortle.
Evolve from Cranidos
well, i got my cranidos's under ground. when you are digging you might find skull fossils. take the fossils to a guy the oreberg museum. go outside then back in and the guy will give you a cranidos
You can evolve Cranidos in Platinum and Diamond, but then you have to trade.
Alright actually you can get Cranidos in pearl. All you need is the national pokedex. Go back to the underground until you find the fossil but you do need the national pokedex to find it.
