Tek Rex Egg & Breeding Calculator

Breeding the Tek Rex produces fertilized eggs that require careful temperature control. 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.

The baby Tek Rex takes approximately 3 days and 20 hours to fully mature at default rates - at a glacially slow pace - plan for a multi-day commitment. The most labor-intensive part is the baby phase (0–10% maturation) when it can't use a Feeding Trough yet.

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 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%

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.

Maturation has three phases: 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.

Imprint bonuses are significant: a fully imprinted Tek Rex gains 30% extra damage and damage resistance with its imprinter mounted. 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 Tek Rex. Expect ~556 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.

The multiplier feature helps plan large-scale Tek Rex raises by totaling food across all babies. 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 Tek Rex is a tamable, carnivore creature in ARK: Survival Ascended. It belongs to the Variant category.

Dealing 100% base Melee Damage, the Tek Rex brings decent hitting power to the table. The Tek Rex has 1,100 base Health - solidly tanky. Stamina sits at 420 base, providing good endurance. It carries 500 base Weight - excellent carrying capacity.

You'll need to knock the Tek Rex unconscious before taming it. Tranquilizers are the standard approach. For best results, use Exceptional Kibble - it gives the highest taming efficiency.

Once tamed, the Tek Rex is primarily used for resource harvesting, excelling at gathering specific materials. It reproduces by laying eggs, which must be incubated between 32°C and 34°C. Defeating one in the wild grants 30 base XP. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.
