Thanks for that, I wasn’t sure about argentinosaurus cuz I’d heard about other really big sauropods and I wasn’t entirely sure. But you’re actually wrong about the t-Rex. The Rex in game is, according to Ark lore, a fictional tyrannosaurus subspecies called Tyrannosaurus Dominus, not a tyrannosaurus Rex. But tribes still call it the Rex. I got that info from the ‘Rex’ dossier.
