Lystrosaurus Egg & Breeding Calculator
Breeding the Lystrosaurus produces fertilized eggs that require careful temperature control. Incubation temperature must stay between 24°C and 28°C - use Air Conditioners, Standing Torches, or Dimetrodons to maintain the range. At the correct temperature, the egg hatches in approximately 49 minutes.
After hatching or birth, the baby Lystrosaurus matures at a medium pace, reaching adulthood in about 15 hours and 25 minutes at 1x maturation. The most labor-intensive part is the baby phase (0–10% maturation) when it can't use a Feeding Trough yet.
Offspring inherit parental stats and have a small chance to mutate, gaining +2 levels in a random stat. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.
Raising a baby Lystrosaurus involves three maturation phases: Baby (0–10%) lasts ~93 min and requires constant hand-feeding. Juvenile (10–50%) spans ~6h - it can eat from a Trough now. Adolescent (50–100%) takes ~8h - continues eating from troughs, nearly fully grown.
Don't skip imprinting - each successful imprint boosts the Lystrosaurus's stats, and hitting 100% grants a 30% combat bonus when the imprinter rides it. Imprint requests include cuddling, walks, and specific kibble - check the wiki for which kibble to stockpile.

Planning a mass raise? The Lystrosaurus raising calculator breaks down food needs per phase so nothing goes to waste. The Baby phase (0–10%) takes ~93 minutes and is the most hands-on, requiring direct feeding or a Maewing.
Raising multiple Lystrosaurus simultaneously? Set the dino count and the calculator scales food requirements automatically. Match your food choice to your play schedule - longer spoil timers mean less babysitting.

During the Baby phase (0-10%), you must hand-feed or use a Maewing to nurse. From Juvenile (10%+), dinos can eat from a Feeding Trough on their own. Use Preserving Salt in troughs to double spoil times.
ARK: Survival Ascended features the Lystrosaurus as a tamable, herbivore creature that survivors will encounter in the wild. It belongs to the Support category.
Its base Melee Damage sits at 100%, giving it solid damage output. Starting at 90 Health, it's extremely fragile. Stamina sits at 100 base, providing tires quickly. A base Weight of 90 means minimal inventory space.
This is a passive tame: no tranquilizers needed. Get close without startling it, then offer food from your last hotbar slot. Its preferred food is Rare Flower.
As a tame, the Lystrosaurus earns its keep through resource gathering, making tedious farming runs much faster. Breeding produces fertilized eggs that hatch within a 24°C–28°C temperature window. Defeating one in the wild grants 0.5 base XP. It can be cloned at a Cloning Chamber for 0.33 Element plus 0 Element per level.
