I'm no expert, but I don't think Aerodactyl is too powerful.  I don't know if it got hugely improved in Gen V, so maybe I shouldn't be saying anything.  Also, my character has an attack advantage over rock so again maybe I shouldn't be weighing in.<br/><br/>For what it's worth, I don't have a problem with it.   Could be difficult to explain how the character at the starting level for this game has a rare, extinct Pokemon, but I can already think of a dozen or two different scenarios that explain it well enough.<br/><br/>Welcome to the game Pink.
