Shastasaurus Egg & Breeding Calculator

The Shastasaurus gives live birth after mating, skipping the egg-incubation step entirely. Gestation takes approximately 8 hours at default rates.

Full maturation from baby to adult takes ~7 days and 17 hours (1x rate), progressing over an extremely long period, one of the longest in the game. 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 dinosaur is in its mother's womb, requiring time and care from the mother for successful gestation and birth.

The hatched dinosaur, now a baby, needs constant attention and food placed directly in its inventory to survive, or a nearby Maewing to take care of its needs.

Juvenile

10% - 50%

37:02:13

The dinosaur reaches the juvenile stage, where it can now eat from a feeding trough, reducing the need for direct feeding.

Adolescent

50% - 100%

46:17:46

The dinosaur reaches the adolescent stage, becoming more independent and able to follow you while continuing to grow toward full maturity.

Raising a baby Shastasaurus 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 Shastasaurus 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 Shastasaurus. Budget ~1111 minutes for the Baby phase - this is when hand-feeding or Maewing nursing is mandatory.

Raising multiple Shastasaurus 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.

Found throughout the ARKs, the Shastasaurus is a tamable, aquatic, piscivore creature in ARK: Survival Ascended. Classified under the Water group.

With 4,500 base Health, the Shastasaurus is one of the toughest creatures in the game. With 100% base Melee Damage, the Shastasaurus has solid damage output. Its base Stamina of 300 gives it decent staying power. Weight capacity starts at 3000, giving it massive inventory space.

After taming, the Shastasaurus is well-suited for deep-sea exploration, cave diving, and ocean resource runs. Breeding is via live birth rather than eggs, simplifying the process. Defeating one in the wild grants 15 base XP. It can be cloned at a Cloning Chamber for 0.88 Element plus 0.01 Element per level.
