The only reason an untamed lystrosaurus will attack you is if you take its egg and the same goes for pteranodon.

Met this thing once and lived to tell the tale.

Do NOT approach them, they are aggressive and merciless and can spot you from afar, if that happens good luck running away...

I stole its egg once… I turned around and it pounced on me nibbled my toes i jabbed it with my spear it broke my spear I got mad and killed it…

I feel bad now😞

How to hatch a lystro egg:

1. get 2 lystros (male and female)

2. Stick them in a house

3. On mobile, enable wandering

4. Whistle stop

5. They will mate, you can see mating progress if you look at the female

6. Get the fertilized egg

7. Get some campfires and drop the egg next to them. (Lit campfires)

If it says too cold or too hot, heat it by holding a torch or cool it by turning off a campfire.

8. Claim the lystro (push the creature rex bone at the top)

9. Give it berries so it doesn't starve

10. Do the imprinting tasks.

11. This works on all reptiles except Griffin and titanosaur.

If you get killed by one of these your a bot

I was scavenging for eggs on the beach, when I found 2 lystro eggs. Swiped those bad boys up when literally 7 LYSTROS JUMPED ME FROM A BUSH.

Don't.

Eat.

The eggs

(I'm done with this comment ;-;)

Lystros are on the lost island even though they say it doesn't

Run fast just run fast or you can use a hatchet to kill it

The walking fridges of ark. Hungry? Find a beach find a lystra and away you go.

Fun fact: This is the only nonmammal creature in the game closest to humans.

If you see it being attack rescue it DO it just rescue it NOW!

to kill this creature you need 50 gigas, 25 carcharodontosaurus, 30 rexes, 1 dragon… and of course 500 overseers

Battle this one in time for this dinospur

Everyone how sees them Kill the them Now!!

*takes egg from them* *them* come here Boah

Biden

U encounter this u must

1 murder it

2 make sure it is dead

3 shoot it just to make sure this useless piece of trash will never breath again

4 cut its heart out with ur bear hands

5 congratulate ur self from not taking the 2nd most annoying thing I hav found so far

Saw one and stole it’s egg and it sent me to hell

Use caution, very aggressive and can one shot most Dino’s including Bronto and even Giga! Saw it with my own eyes. Passive tame, but be really careful, very lethal. Useful tame, strong and provides xp boost after being pet. 10/10

Warning: these things even at level 3 are devastating kill sarcos no joke
