Is there any way to make Aerodactyl learn Head smash. Thanks to rock head it would not take recoil damage and would just sweep, but can it learn Head smash in any way?
Unfortunately there is no way to teach Aerodactyl Head Smash. Imagine if it got Brave Bird + Head Smash ...
No, unfortunately not. Sorry.
Hope I helped. :)
