Ankylosaurus [PvE Cross]

Ankylosaurus is the best dino to farm metal with and has a weight reduction for it.
The fastest method to farm metal is to fly over a metal node with an Argentavis/Rhyniognata holding an Ankylo with your tribemate riding it and your tribemate hitting the rocks. When the flyer gets heavy, just bring the Ankylo to the forge.
Alternatively, if you're farming solo, you can hover the Ankylo with a flyer over a metal node and it will hit it automatically.
All Ankylos are 100% imprinted, the colors are guaranteed for best stats and random for older stats.
