The Root Fossil (Japanese: ねっこのカセキ Root Fossil) is a fossil that Lileep can be resurrected from.


In Ruby and Sapphire, it can be found on Route 111 and in Emerald it can be found in the Mirage Tower on Route 111.

In HeartGold and SoulSilver, it can be found by smashing rocks at the base of the cave in Route 47.

In Black and White you can get a random fossil from a guy in twist mountain, but after getting a fossil you must wait 24 hours until you can get another one.
