In mobile, if you feed your tamed lystro some narcotics (any), it will give itself and your dinos the xp buff. You can pet your lystro and when the buff expires, feed some narcotics, to extend its buff, so you don’t have to wait again to pet him. Up this to inform bobs

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

Taming one can be a good way to level up. Once tamed they can be pet to obtain a free buff to epericence for you and your dinos in range. Last about five minutes.

One of the funniest little dinos in the game.

Act like a dog

Walks and run like a dog

Gives XP boost

And he does a backflip! :D

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

You can't pick it up like a Dodo so i'd recommend leveling up his movement speed as well. :)

If you pet it, dinos within a certain radius will get almost double the xp! ( 1.7 x more to be exact ) That’s a 35% boost! If only the range was higher.

Build a 2 wide 1 high rectangle ( it can be as long as you like) with ramps coming off one side of it. Bring all of your favourite creatures and place them on top of the rectangle and put a bunch of lystros inside the rectangle with a door on one side. Put a trough somewhere and BAM! You now have yourself an xp farm. Just go inside and pet the lystros every so often.

I would say those are compact moving chests. They are easy to tame
