Reviving ancient creatures from fossilized remains has always been one of the most exciting traditions in the Pokemon franchise. In the Kalos region of Pokemon X and Y, trainers are introduced to a fresh pair of prehistoric companions alongside several returning classics. Securing these ancient allies requires exploring specialized caverns and understanding the unique requirements needed to evolve them into their final, powerful forms.
Discovering the Jaw and Sail Fossils in Glittering Cave
Your primary destination for finding new fossils in the Kalos region is the mysterious Glittering Cave, located just beyond Route 9. Inside this dark cavern, you will navigate deep into the shadows where members of the villainous Team Flare are cause for trouble. After defeating the grunts, a resident researcher will reward your efforts by letting you choose between two distinct prehistoric artifacts.
The choice you make here permanently determines the first ancient Pokemon you can add to your party during the main story. Selecting the Jaw Fossil allows you to obtain Tyrunt, a fierce Rock and Dragon-type reptile. Opting for the Sail Fossil grants you Amaura, an elegant Rock and Ice-type quadruped known for its colorful, sail-like sails.
Hunting for Returning Classic Fossils in the Postgame
Once you successfully defeat the Elite Four and claim the title of Kalos Champion, the fossil hunting experience expands significantly. Returning to the deepest chambers of Glittering Cave unlocks the ability to smash breakable rocks using the Rock Smash hidden machine. Cracking these boulders open gives you a random chance to discover ancient remains from previous generations.
Trainers can discover iconic treasures like the Helix Fossil for Omanyte, the Dome Fossil for Kabuto, and the Old Amber for Aerodactyl. Version-exclusive mechanics also influence your search, meaning certain older generation options drop more frequently depending on whether you play X or Y. This makes trading with other players an excellent strategy for completing your historical Pokedex collection.
How to Revive Your Ancient Discoveries
After successfully securing your desired prehistoric items, you must take them to the Fossil Lab located in Ambrette Town. The scientists inside run a advanced extraction device capable of regenerating these stony remains back into living creatures. Simply speak to the researcher at the counter, select the artifact from your inventory, and ensure you have an open slot in your current party.
Every regenerated creature will emerge at level 20, ready to be trained or safely stored away in your PC boxes. This resurrection process is completely free and can be repeated as many times as you find eligible rocks to smash. It is the perfect way to test out diverse type combinations for your upcoming gym battles.
Evolution Requirements for Kalos Prehistoric Pokemon
Evolving the sixth-generation prehistoric Pokemon relies entirely on a unique combination of leveling up and the in-game clock. To transform Amaura into the massive Aurorus, you must train it to level 39 specifically during the nighttime hours. If the internal clock reads daytime when the level is reached, the evolution will fail to trigger until the sun sets.
Conversely, Tyrunt follows the exact opposite pattern to transform into the mighty Tyrantrum. You must raise Tyrunt to level 39 exclusively during the daytime hours for the evolutionary sequence to begin. Planning your training sessions around these environmental factors ensures your prehistoric party reaches its maximum potential without unnecessary delay.
