I am assuming you mean Amaura, its pre-evolution. Amaura revives from a Sail Fossil, which can be given by a Scientist in Glittering Cave after you defeat Team Flare. Once you receive the Fossil, take it the museum in Ambrette Town and Amaura will revive. Amaura starts out at level 20 and it evolves into Aurorus at level 39 in night time.
Machop evolves into Machoke starting at level 28, and then Machoke evolves into Machamp when traded.

In Generation VI (X and Y), it can be found in Glittering Cave.
