Lost Yutyrannus
Lost Yutyrannus Egg & Breeding Calculator
Full maturation from baby to adult takes ~7 days and 17 hours (1x rate), progressing at a glacially slow pace - plan for a multi-day commitment. 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.
Raising a baby Lost Yutyrannus involves three maturation phases: Baby (0–10%) lasts ~1111 min and requires constant hand-feeding. Juvenile (10–50%) spans ~74h - it can eat from a Trough now. Adolescent (50–100%) takes ~93h - continues eating from troughs, nearly fully grown.
Imprinting during maturation provides permanent stat bonuses. At 100% imprint, the Lost Yutyrannus gains 30% bonus damage and resistance when ridden by the imprinter. You'll be asked to cuddle, walk, or feed specific kibble at regular intervals during maturation.

The raising calculator above shows exactly how much food you need for each maturation phase of the Lost Yutyrannus. Budget ~1111 minutes for the Baby phase - this is when hand-feeding or Maewing nursing is mandatory.
Raising multiple Lost Yutyrannus 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.
