Breeding the Acrocanthosaurus produces fertilized eggs that require careful temperature control. Incubation temperature must stay between 43°C and 44°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 Acrocanthosaurus takes approximately 3 days and 20 hours to fully mature at default rates - over many real-world days, demanding serious time investment. 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 Acrocanthosaurus'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 Acrocanthosaurus 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.

The raising calculator above shows exactly how much food you need for each maturation phase of the Acrocanthosaurus. 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 Acrocanthosaurus raises by totaling food across all babies. Different food types have different spoil timers - factor that into which food you stockpile.
