Corrupted Rex Egg & Breeding Calculator
The Corrupted Rex reproduces by laying fertilized eggs after mating. 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.
Full maturation from baby to adult takes ~3 days and 20 hours (1x rate), progressing over an extremely long period, one of the longest in the game. During the baby phase (0–10%), hand-feed it directly. From 10% onward (juvenile), it can eat from a Feeding Trough.
Offspring inherit parental stats and have a small chance to mutate, gaining +2 levels in a random stat. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.
The Corrupted 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.
Imprint bonuses are significant: a fully imprinted Corrupted Rex 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.

Use the raising calculator to plan food requirements for raising Corrupted Rex babies through all three growth stages. Budget ~556 minutes for the Baby phase - this is when hand-feeding or Maewing nursing is mandatory.
Adjust the dino count to calculate food for multiple Corrupted Rex babies at once - essential for batch breeding operations. Consider food spoilage when choosing what to feed: Kibble lasts days, while Raw Meat spoils in minutes.

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 Corrupted Rex, a carnivore creature in ARK: Survival Ascended, is a notable presence across multiple maps. It falls within the Variant classification.
Stamina sits at 420 base, providing solid stamina reserves. Dealing 100% base Melee Damage, the Corrupted Rex brings solid damage output to the table. The Corrupted Rex has 1,100 base Health - solidly tanky. Weight capacity starts at 500, giving it an enormous weight pool.
The Corrupted Rex roams the ARK as a wild, untamable creature. It reproduces by laying eggs, which must be incubated between 32°C and 34°C. A wild Corrupted Rex is worth 30 base experience when killed. It can be cloned at a Cloning Chamber for 0.87 Element plus 0.01 Element per level.
