When you pet it they give your Dino’s an XP boost just for standing there. Perfect for leveling up tames if you are unable to, for lack of ability or if trying to keep a low profile in the area to not alert other tribes.
Find a lot of rare flowers in beaver dams and use them to tame lystrosaurus, then use their eggs to get diplodocus. Use diplodocus eggs to get allosaurus. These dinos are a great way to move up fast on PvP servers by getting a lot of allosaurus
Lystrosaurus, this little reptile could have it all in the fierce war between the dodo and kairuku. They are like little puppy dogs, which means you pet them and they do some cool trick, like a backflip. They are great to have around bases, as they provide an xp buff so other dinos lvl quicker. Lystro army is also funny, I mean look at their little legs they're so adorable yes you are little lystro! Oops, gotta keep it professional here. Yeah they're great
