In Prehistoric Farm on Roblox, raising creatures centers entirely around dinosaur feeding. The game operates on a single developer-confirmed growth rule: keep your dinosaur's belly over half full so it keeps growing. If its belly drops to half or below, growth stops until you feed it again.
Whether you have just placed your first Cambrian hatchling or are managing a bustling herd on your ranch, understanding diet compatibility, coin management, and the feeding routine ensures your creatures reach mature, rideable stages without unnecessary delays.
The Core Feeding Rule: Belly Fullness and Growth
According to official game descriptions from developer Project Mirvy, dinosaurs require active nourishment to develop from tiny Newborns into massive Elders.
The growth mechanic functions on a straightforward threshold:
- Belly Above Half Full: The creature remains in an active growing state, steadily progressing through its life stages.
- Belly at Half Full or Below: Growth stalls completely. If you notice your dinosaur has stopped growing, an empty or half-empty stomach is the direct cause.
Because the system requires fullness to stay strictly above the halfway mark, feeding cannot be treated as a one-time event. You must regularly return to your ranch pens to top off the hunger meter.
Food Types and Diet Compatibility
Feeding requires matching the right food to the specific creature. Buying random provisions without checking diet compatibility will not resolve hunger.
In-game food vendors, such as Bramble's Feed, offer primary staples purchased with Coins:
- Vegetables: Required for herbivores and plant-eating species.
- Meat: Required for carnivores and predatory dinosaurs.
- Player-Caught Fish: Community wikis document that player-caught fish (such as mackerel, sardines, and swordfish obtained through fishing) can be fed to meat-eaters. However, whether caught fish replenish the exact same Belly volume as store-bought meat remains unconfirmed, and fish cannot be fed to plant-eating dinosaurs.
Always inspect your creature to confirm its diet type before spending your hard-earned Coins at the food stall.
How to Feed Dinosaurs on Your Ranch
Feeding takes place directly on your personal ranch plots after an egg finishes incubating and is collected from the hatchery.
- Earn Coins through Digging: Food is not free. Ensure you have a working balance of Coins earned by digging fossils, selling surplus finds, or uncovering buried treasure.
- Purchase Compatible Food: Head to the food vendor on the home island and buy food matching your dinosaur's specific diet (meat or vegetables).
- Equip Food to Your Hotbar: Place the purchased food items into your active inventory slots.
- Approach the Dinosaur: Walk up to the creature placed on your ranch plot and interact with it to feed.
- Inspect the Belly Meter: Check the creature's belly status to confirm the meter has climbed comfortably above the halfway mark.
Feeding and Care Milestones
Dinosaurs do not remain tiny forever. Consistent care carries them through several documented growth phases:
| Life Stage | Ranch Status and Care Role |
|---|---|
| Newborn | Freshly collected from the hatchery and placed on the ranch. Extremely small; requires immediate feeding to begin development. |
| Juvenile & Subadult | Intermediate growth stages. Requires continuous Belly monitoring above half full to maintain transition timers. |
| Adult & Elder | The mature stages of growth. Reaching full size unlocks the ability to mount and ride your partner dinosaur across the islands. |
Once a dinosaur reaches its fully grown Elder stage, you can mount it to travel faster across land and explore new territory.
Herd Scaling and Upkeep Costs
Managing food costs requires advance planning as your ranch expands. Multiple sources confirm that food costs scale upward once you raise more than one Elder.
Because each active dinosaur draws on your food supply, expanding your herd increases your recurring Coin expenses. If you plan to hatch multiple high-tier creatures, ensure you have upgraded your shovel and maintained a steady loop of fossil excavations to support the higher daily upkeep costs.
Frequently Asked Questions
Why has my dinosaur stopped growing?
A dinosaur stops growing whenever its Belly level drops to half full or below. To resume growth, purchase compatible food (meat or vegetables) and feed the creature until its meter is safely over the halfway mark.
Can you feed every dinosaur caught fish?
No. Fish compatibility is only documented for meat-eating dinosaurs. Plant-eating species require vegetables purchased from the feed stall.
Do fully grown Elders still need to be fed?
While riding unlocks once a dinosaur reaches full maturity, herd upkeep rules indicate that maintaining multiple Elders increases overall food expenses on the ranch. Keeping Coins on hand ensures all your creatures stay properly maintained.
