The baby Revenant Brontosaurus takes approximately 3 days and 20 hours to fully mature at default rates - at a glacially slow pace - plan for a multi-day commitment. During the baby phase (0–10%), hand-feed it directly. From 10% onward (juvenile), it can eat from a Feeding Trough.

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 Revenant Brontosaurus'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 Revenant Brontosaurus 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.

Planning a mass raise? The Revenant Brontosaurus 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 Revenant Brontosaurus babies at once - essential for batch breeding operations. Match your food choice to your play schedule - longer spoil timers mean less babysitting.
