In Prehistoric Farm on Roblox, digging up ancient remains across time-period islands is only half the journey. To turn bone fragments into living creatures, you must bring complete fossil sets back to Dr. Ivy at the DNA Lab.
The DNA Lab serves as the central hub for resurrecting extinct species. Once you understand where the lab is located, how fossil exchanges work, and how the incubation pipeline operates, you can efficiently expand your ranch from early Cambrian invertebrates to rideable apex predators.
Where to Find Dr. Ivy's DNA Lab
Dr. Ivy’s DNA Lab is located on the central Home Island (the main spawn island), positioned close to your player ranch and the boat launch dock. In recorded gameplay, players easily spot the spawn area from sea by its prominent waterfall and home harbor.
The Home Island clusters several essential services together:
- Dr. Ivy's DNA Lab for converting completed fossil collections into eggs.
- The Hatchery, where ready dinosaurs are picked up after incubation.
- The player ranch, where newly hatched creatures are placed and raised.
- Upgrades and merchant stalls, including the shovel merchant, boat vendor, and feed supplies.
Because you cannot extract DNA or generate eggs directly at remote dig sites, you must always take a boat back to the home harbor once your collection is finished.
How to Trade Completed Fossil Sets for Eggs
The official game tutorial states: "Collect a full set of fossils and bring them to Dr. Ivy to grow an egg." Individual fossil pieces cannot be restored on their own; only complete species sets can be exchanged.
1. Complete a Fossil Set
Equip your shovel and sail to an unlocked period island. When excavating dig spots, hold down the action button and release when the meter lands in the green zone to maximize your rewards. Digging returns either random fossils for that island's era, empty misses ("No fossil"), or currency bonuses like buried treasure.
Once you collect every required piece for a specific animal, your collection interface updates with the status "Ready to extract DNA." The starting Cambrian sets require five or six matching fossils per creature, depending on the UI version logged in gameplay tests.
2. Speak to Dr. Ivy
Return to the Home Island and step inside the DNA Lab. Speak with Dr. Ivy, who greets visitors with: "I'm Dr. Ivy. I bring fossils back to life. Got any samples for me?"
3. Select "Trade fossils for an egg"
Interact with the conversion prompt. A brief animation plays, the completed fossil set is consumed, and Dr. Ivy creates a species-specific dinosaur egg on the spot without charging an extra coin fee in documented versions.
Incubating Eggs and Hatch Times
Securing an egg from Dr. Ivy is immediately followed by the incubation phase inside the facility. Official directions summarize the sequence as warming the egg in an incubator and watching it hatch.
Observed Incubation Countdown Timers
Unlike instant item drops, eggs require incubation time before they hatch into live animals. Gameplay sessions and independent community documentation record differing incubation times based on species and creature rarity:
| Creature / Tier | Observed Incubation Duration | Source Type |
|---|---|---|
| Common (e.g., tutorial/early species) | Approximately 1 minute | Third-party wiki reference |
| Uncommon (e.g., Tiktaalik) | 2 minutes 30 seconds | Recorded player session |
| Rare (e.g., Hallucigenia in early runs) | Approximately 5 minutes | Recorded player session |
| Epic | Approximately 10 minutes | Third-party wiki estimate |
| Legendary | Approximately 20 minutes | Third-party wiki estimate |
Note: The official developer description does not publish an exact timing table. Displayed countdowns may vary between game balance updates, so always check the specific on-screen timer above your active incubator slot.
What You Can Do During Incubation
You are not required to stand idle inside the DNA Lab while the countdown ticks down. In recorded runs, players leave the lab to fish off the docks or gather coins. The game interface provides distance announcements as the hatch nears completion, alerting players when only one minute or twenty seconds remain.
Collecting Your Dinosaur at the Hatchery
When the countdown reaches zero, the incubation step concludes. Dr. Ivy’s lab does not automatically deposit the live animal into your inventory or directly into your pasture.
- Walk over to the Hatchery station adjacent to the lab area.
- Confirm the hatch completion notice.
- Collect your newborn creature.
- Carry the hatchling directly to your ranch and place it into your pen.
From this point onward, the creature enters its life-cycle progression, starting as a Newborn. Per developer instructions, you must keep the animal's belly over half full by feeding it compatible food so it steadily grows into an Adult and Elder that you can eventually mount and ride across the islands.
Upgrades That Support the DNA Lab Loop
Progressing through higher-tier fossil sets requires upgrading your equipment on Home Island so you can access later geological eras.
- Starter Wooden Shovel: Digs exclusively on the starting Cambrian Island.
- Bronze Shovel (2,500 Coins): Documented to unlock excavation on Devonian Island, where creatures like Tiktaalik are discovered.
- Higher Shovel Tiers: Tiers priced at 12,000 coins and above expand access into Triassic, Jurassic, and Cretaceous grounds.
- Boat Upgrades: Better boats (such as the 4,000-coin rowboat upgrade) increase transit speed across the open sea, cutting down travel time between remote excavation mounds and the Home Island DNA Lab.
Frequently Asked Questions
Can you extract DNA at excavation dig sites?
No. Dig sites only award raw fossil pieces and coins. The "Ready to extract DNA" prompt requires you to sail back to Home Island and interact directly with Dr. Ivy at the lab.
Can sea reptile eggs from the Sunken Grotto be hatched at the DNA Lab?
In official materials, sneaking into the Sunken Grotto to steal sea reptile eggs is classified as an open-sea exploration activity. The developer documentation links the DNA Lab, incubator, and ranch loop strictly to fossil-restored species, leaving stolen sea reptile egg functions unverified.
What happens if I log off during egg incubation?
Incubation runs on a standard countdown timer. Checking your active incubator slot upon returning to the DNA Lab allows you to resume tracking or immediately collect the completed hatch from the Hatchery if the timer has expired.
