Prehistoric Farm dinosaurs: hatch, feed, grow, and ride ranch partners

Eggs to rideable Elders

Trade sets at Dr. Ivy, incubate, keep belly over half full, ride from Subadult, then unlock flyers at Sky Spires.

Egg route

Matching set → Home Island DNA Lab → Trade fossils for an egg → incubate → hatchery collect.

  1. Complete a matching fossil set for one creature on a dig island.
  2. Sail back to Home Island. Use the waterfall landmark if you lose the dock heading.
  3. Talk to Dr. Ivy at the DNA Lab: "I'm Dr. Ivy. I bring fossils back to life. Got any samples for me?"
  4. Choose Trade fossils for an egg when the set is ready.
  5. Place the egg in an open incubator slot and wait out the timer on that egg.
  6. Collect at the hatchery, place the hatchling on a ranch slot, and start feeding.

Incubator slots list

Two free slots cover early play. Slot 3 costs 30,000 and unlocks before slot 4 at 50,000. Robux slots add more capacity. Fish or dig while timers run. Skip Hatching only skips the hatch cutscene. Tutorial eggs can finish in 10 to 15 seconds; normal eggs use the countdown on the slot.

Growth and belly

Growth runs Newborn → Juvenile → Subadult → Adult → Elder. Buy Meat (12) or Veggies (8) at Bramble's Feed, or grab x10 / x50 packs (Meat 120 / 600, Veggies 80 / 400). Put food on the hotbar, stand next to the dino, and press F. Match diet on the panel: carnivores can take meat or fish; herbivores need plants. Growth stops at half belly or lower. After Elder, stop feeding to save coins.

Growth timers table

Approximate stage times by rarity. Blank cells mean read the meter on your ranch dino.

RarityNewborn → JuvenileJuvenile → SubadultSubadult → AdultAdult → Elder
Common~3 min~8.5 min~18 min—
Uncommon~7 min~16.5 min~35 min~70 min
Rare——~120 min—
Epic—~54 min—~240 min
Legendary—~135 min——

Hatch sizes

The same species can hatch Normal, Big, or Giant. Size rolls at hatch and is separate from rarity, so a Common can hatch Giant and a Legendary can hatch Normal. Many eggs share the same shell look; rarity shows on the bottom color.

Riding

Riding unlocks from Subadult. Newborn and Juvenile stay on foot. Open the planner, assign a Partner, then Hold R. The partner follows on land. Aquatic mounts must enter water first; use Shift + Space for a water jump. A grown aquatic dino can replace a boat for island travel, but it does not replace shovel dig gates.

Hatch timers table

Approximate hatch times by rarity. Tutorial eggs can finish in 10 to 15 seconds. Use the countdown on your incubator slot.

RarityTimer
Common~1 minute
Uncommon~2 min 30 sec
Rare~5 minutes
Epic~10 minutes
Legendary~20 minutes

Ranch notes

Eight ranch slots. Prefer Epic and Legendary when space is tight. An Epic juvenile can make about 210 coins per minute, so park rare dinos first and sell Common and Rare fossils when slots are full. Codes can grant eggs and fragments: UPDATE1 includes a Velociraptor egg, and SORRYFORDELAYSGUYS grants Nessie Fragments.

Cambrian creatures list

Six starter species. Each needs five matching fossils.

Flyer / Sky Spires

Clara's quest: Silver shovel, 20 Puffer, 70 Triassic digs, 10,000 coins.

  1. Buy Digby's Silver shovel so you can dig on Triassic.
  2. Sail toward Auction Island (upper center of the map), go behind Auction, and follow the buoy line to Sky Spires.
  3. Talk to Clara and accept the quest.
  4. Return to Home Island, buy bait up to 15, and catch 20 Puffer fish.
  5. Hand the Puffer fish back to Clara at Sky Spires.
  6. Dig 70 times on Triassic with the Silver shovel.
  7. Return to Clara, pay 10,000 coins, and collect the flyer egg.
  8. Incubate and hatch. Top-tier flyers are rare (around 5%). Repeat the quest if you want another roll.
  9. Example hatch: Legendary flyer, Adult, Normal size, 257 kg. Your weight and rarity will differ.

Stock Puffer fish on the fishing page. Silver shovel pricing is on upgrades.

FAQ

How do I get my first egg?

Complete a matching fossil set, return to Home Island, and talk to Dr. Ivy at the DNA Lab. She trades fossils for an egg.

Why did growth stop?

Belly hit half or lower. Feed at Bramble's (Meat 12, Veggies 8), press F next to the dino, and match its diet.

When can I ride?

From Subadult. Assign a partner, then Hold R. Aquatic mounts need water first; Shift + Space for a water jump.

What hatch sizes exist?

Normal, Big, or Giant. Size rolls at hatch and is separate from rarity.

How do I unlock a flyer?

Clara's Sky Spires quest: Silver shovel, 20 Puffer, 70 Triassic digs, 10,000 coins. Steps are in the flyer section above.

Do I need Robux incubators?

No. Two free slots cover early play. Coin slots 3 and 4 (30,000 / 50,000) come first if you need more eggs at once.

What should I feed my dinosaur?

Match the diet on the dino panel. Carnivores can also eat fish. Details are in Growth and belly above.

How do I read egg rarity?

Check the bottom color of the egg. Size (Normal, Big, Giant) is a separate roll.
