The Pokemon Company revealed the two fossil Pokemon for Pokemon X and Y this weekend: the tyrannosaurs-looking Tyrunt and the whimsical Amaura — both of which can evolve into more powerful Pokemon.
Tyrunt can be obtained by reviving the one hundred million year-old Jaw Fossil, and according to the Pokemon website will throw a fit when he is displeased with something. He is a Rock/Dragon type Pokemon and his evolved form is Tyrantrum, a large creature reminiscent of a tyrannosaurus.
Amaura is a Rock/Ice type Pokemon that can be obtained by reviving the Sail Fossil. Amaura uses a new ability, Refrigerate, which will turn Normal-type Pokemon moves into Ice-type moves. Amaura evolves into Aurorus, which can blast enemies with cold air and form walls of ice.
