Argentinosaurus is said to be the biggest dinosaur known to man. I love the Giganotosaurus, but we still need bigger! Adding an herbivore that's dominant to all species on ARK would be very cool. Maybe it'll be 2 times bigger than a Giga?

It insta-kills most creatures (when forced to attack); but animals like Gigas, Spinos, T-Rexs, Carnos, and Raptors do 20x damage to Argentinos than regular animals. To tame this monster, you'll need
sateberries. Sateberries are crafted with all of the types of berries including narcoberries.

Edit: Changed how sateberries work.
