These guys are adorable and very precious. I have one tamed and I always take him wherever I go. They dont have much use except for their xp boost when you pet them and for lystro kibble, but I love keeping him as a pet. A weird lizard pig thing can really make a base more lively.
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
