Alpha Skeletal Rex Egg & Breeding Calculator

After a successful mate, the Alpha Skeletal Rex lays a fertilized egg. Incubation temperature must stay between 32°C and 34°C - use Air Conditioners, Standing Torches, or Dimetrodons to maintain the range. At the correct temperature, the egg hatches in approximately 4 hours and 59 minutes.

After hatching or birth, the baby Alpha Skeletal Rex matures over many real-world days, demanding serious time investment, reaching adulthood in about 3 days and 20 hours at 1x maturation. Hand-feeding is required until 10% maturation. After that, a Feeding Trough handles the rest.

Mutations can add +2 levels to any stat and change colors. Stacking mutations across generations is the key to min-maxed breeding lines. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.

The dino is inside an egg, needing specific conditions to incubate and hatch. The ideal temperature range is 32 - 34 °C.

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%

18:31:06

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

Adolescent

50% - 100%

23:08:53

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

The Alpha Skeletal Rex's growth progresses through three stages: Baby (0–10%) lasts ~556 min and requires constant hand-feeding. Juvenile (10–50%) spans ~37h - it can eat from a Trough now. Adolescent (50–100%) takes ~46h - continues eating from troughs, nearly fully grown.

Imprinting during maturation provides permanent stat bonuses. At 100% imprint, the Alpha Skeletal Rex gains 30% bonus damage and resistance when ridden by the imprinter. Keep various kibble types on hand, as imprint requests are randomized between cuddles, walks, and kibble feeding.

Planning a mass raise? The Alpha Skeletal Rex raising calculator breaks down food needs per phase so nothing goes to waste. Expect ~556 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.

Adjust the dino count to calculate food for multiple Alpha Skeletal Rex babies at once - essential for batch breeding operations. 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 Alpha Skeletal Rex as a carnivore creature that survivors will encounter in the wild. Classified under the Ignore group.

Its base Melee Damage sits at 100%, giving it decent hitting power. With 17,500 base Health, the Alpha Skeletal Rex is an absolute bullet sponge. Its base Stamina of 420 gives it solid stamina reserves. A base Weight of 500 means an enormous weight pool.

The Alpha Skeletal Rex roams the ARK as a wild, untamable creature. Breeding produces fertilized eggs that hatch within a 32°C–34°C temperature window. Killing a wild Alpha Skeletal Rex yields 885 base XP. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.
