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
No need to knock out as it is a passive tame. Berries is best if a player does not have Rare Flowers. Easy tame, however, annoying because it will continue to walk around. Trapping it in a small area would best make it an easier tame and less wandering.
Once tamed, petting the Lystro will give experience boost to any dinos as well as players that are in its radius. I believe it lasts 5 minutes. So, when crafting a bunch of items, pet these little dogs.
Fun fact the Lystro is an ancient ancestor of mammals. When you see one tame it, they can be very rare. I suggest using mejoberries. These guys are tough, but can't take on fast dinos like Raptors. Trust me I learned the hard way... "Your Lystrosaurus lvl 13 was killed by lvl 23 Raptor".
