R-Thylacoleo
Variant
R-Thylacoleo Egg & Breeding Calculator
Full maturation from baby to adult takes ~2 days (1x rate), progressing slowly. Hand-feeding is required until 10% maturation. After that, a Feeding Trough handles the rest.
Each baby inherits stats from both parents with a chance of mutation - +2 wild levels to a random stat plus a color change. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.
The R-Thylacoleo's growth progresses through three stages: Baby (0–10%) lasts ~292 min and requires constant hand-feeding. Juvenile (10–50%) spans ~19h - it can eat from a Trough now. Adolescent (50–100%) takes ~24h - continues eating from troughs, nearly fully grown.
Imprint bonuses are significant: a fully imprinted R-Thylacoleo gains 30% extra damage and damage resistance with its imprinter mounted. Imprint requests include cuddling, walks, and specific kibble - check the wiki for which kibble to stockpile.

The raising calculator above shows exactly how much food you need for each maturation phase of the R-Thylacoleo. Budget ~292 minutes for the Baby phase - this is when hand-feeding or Maewing nursing is mandatory.
Raising multiple R-Thylacoleo simultaneously? Set the dino count and the calculator scales food requirements automatically. Different food types have different spoil timers - factor that into which food you stockpile.

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.
The R-Thylacoleo, a tamable, carnivore creature in ARK: Survival Ascended, is a common sight across multiple maps. It belongs to the Variant category.
At 679 base HP, the R-Thylacoleo is solidly tanky. With 105% base Melee Damage, the R-Thylacoleo has respectable melee power. Stamina sits at 400 base, providing solid stamina reserves. It carries 400 base Weight - good carrying capacity.
Taming the R-Thylacoleo requires rendering it unconscious first - use Tranq Arrows, Darts, or Shocking Tranq Darts to apply torpor. Feed it Extraordinary Kibble for the fastest tame and highest effectiveness bonus.
Once tamed, the R-Thylacoleo is valued for its harvesting efficiency, collecting key resources faster than most tools. Defeating one in the wild grants 5 base XP. It can be cloned at a Cloning Chamber for 0.5 Element plus 0.01 Element per level.
