Is it true Aerodactyl can be found in Glittering caves?

Question

I saw someone find old amber in the caves (X & Y) is it true?

Answer 1

Yes, it is true. Old Amber can be found by smashing rocks in Glittering Cave. They are rare though, so to find Old Amber you will need patience.

And unlike (most of?) the other fossils, you can find Old Amber before defeating the Elite Four.  =D

Answer 2

Alas, the rumour is true! Old Ambers are known to exist!! :D

The Old Ambers are found when using Rock Smash on Rock Smash rocks continuously. You can find items, and one of these items is the Old Amber. Hence, you can revive an Old Amber to create Aerodactyl.

Hope I helped. :)
