This achievement is missable!
After being hunted by a spinosaurus (The Velociraptor/T-Rex that hunts you like the boulders), the Spinsaurus will hit it's head on the wall at the end of the chase.
When he is pacified, go on top of him and use the Ground Pound Attack (Same attack you use to break vases) and this achievement should unlock.
(This achievement is part of the Hidden World, not the main game)
