Fossil Pokémon Tyrunt and Amaura have been revealed for Pokémon X & Y, known as Chigorasu and Amarusu within the Japanese version.
Tyrunt, which looks much like a Tyrannosaurus, is a Rock and Dragon-type and knows the ability Hard Jaw, which boosts the attack power of Bite moves. The Diplodocus-inspired Pokémon Amaura is a Rock and Ice-type which can use Refrigerate, making Normal-type moves become Ice-type.
Pokémon X & Y will release worldwide on October 12th.
