What is Prehistoric Farm?
Prehistoric Farm is a dinosaur ranch simulation and tycoon experience on Roblox developed by Project Mirvy. Players launch boats from a central home island hub to explore prehistoric period islands, unearth ancient fossils with shovels, and trade completed specimen sets for viable eggs at Dr. Ivy's DNA Lab.
After warming eggs inside lab incubators, players retrieve newborns from the hatchery and place them in ranch pens. Keeping each dinosaur's belly over half full allows it to mature through developmental stages into a massive Elder companion that can be ridden across the terrain or used to navigate open waters.

Find Your Next Guide
From your first fossil dig to open-sea exploration, choose the topic you need.
Beginner Guide
Start with fossil digging, egg hatching, and dinosaur care. Follow the core progression toward raising and riding your first dinosaur.
Launch your boat from the home dock and navigate to an accessible geological period island.
Time your shovel swings in the green zone to collect complete fossil sets and coins.
Turn finished specimen sets over to Dr. Ivy at the DNA Lab on the home island to receive an egg.
More details
Warm the egg in an incubator slot, collect your newborn at the hatchery, and feed it past half full.
Digging and Fossils
Release your shovel when the digging meter turns green for a better find. Collect complete fossil sets for egg creation.
Locate marked ground mounds scattered across period islands like Cambrian or Devonian.
Hold down the dig button and release the input when the oscillating slider rests in the green zone.
Collect creature fragments while budgeting for standard empty misses and direct coin rewards.
More details
Excavate glowing dig mounds during nighttime cycles to claim bonus coins alongside fossil drops.
DNA Lab and Egg Hatching
Bring complete fossil sets to Dr. Ivy's DNA Lab to create eggs. Warm your eggs in an incubator to hatch them.
Assemble all required anatomical fragments for a single species until the collection shows ready.
Speak with Dr. Ivy at the DNA Lab on the home island and select trade fossils for an egg.
Place the egg into one of your free incubator slots and let the real-time countdown clock run.
More details
Interact with the nearby hatchery station once the timer reaches zero to claim your newborn.
Dinosaur Feeding and Growth
Keep your dinosaur's belly over half full so it continues growing. Raise dinosaurs from Newborns to Elders and ride them once grown.
Dinosaurs only advance in size while their hunger meter stays strictly above the 50 percent threshold.
Feed store-bought vegetables to herbivores, and provide meat or player-caught fish to carnivores.
Creatures progress sequentially from Newborn through Juvenile, Subadult, and Adult into an Elder.
More details
Reaching maximum Elder maturity unlocks the ability to ride your partner creature across the islands.
Boats and Islands
Buy bigger boats to reach new fossil islands. Explore beyond your ranch to continue your fossil hunt.
The free starter vessel carries two players at 12 knots for short hops to nearby Cambrian Island.
Purchasing larger vessels like the 4,000-coin Banks Dory or motorboats increases speed and seating.
Tool tiers restrict digging across periods, requiring upgrades like the 2,500-coin Bronze Shovel.
More details
Riding a fully grown marine reptile provides open-water transportation without buying a new boat.
Sunken Grotto and Sea Reptile Eggs
Sneak into the Sunken Grotto to steal sea reptile eggs. Discover another egg source alongside Dr. Ivy's fossil conversion.
Sail away from the home island docks using a boat or mount a mature aquatic dinosaur.
Search the open sea without automated waypoints by keeping visual landmarks in sight.
Navigate the secluded grotto using stealth rather than standard shovel excavation tools.
More details
Retrieve sea reptile eggs directly from the nest as an open-sea exploration collectible.
Fishing and Diving
Fish in the open sea. Dive beneath the surface to search for rare catches.
Purchase bait from the dock vendor for 5 coins per bundle and cast directly into coastal waters.
Surface casting yields common hauls including mackerel, sardines, puffer fish, and lucky swordfish.
Heading out into deep water allows players to dive for items classified under rare catches.
More details
The collection tracker features six Cretaceous Seas entries obtained through open-sea fishing.
Mosasaurus Combat Guide
Take on the giant Mosasaurus with spears. Team up with other players to bring it down.
Coordinate with players on your server since the encounter is designed as a multiplayer group battle.
Carry spears into open water as the only recognized combat weapon for the boss fight.
Launch upgraded boats or ride aquatic dinos to reach the marine encounter off the home hub.
More details
Work together to strike the giant Mosasaurus and defeat the open sea apex predator.

How do you hatch eggs in Prehistoric Farm?
Trade a completed creature fossil set to Dr. Ivy at the DNA Lab, place the resulting egg in an incubator slot, wait out the timer, and claim your newborn at the nearby hatchery.
When can you ride dinosaurs in Prehistoric Farm?
Riding unlocks once a dinosaur reaches its fully grown Elder life stage after receiving consistent feeding on your ranch.
How do you reach new islands in Prehistoric Farm?
You can reach farther geological islands by purchasing larger and faster boats from the dock vendor or by riding a mature aquatic dinosaur across the water.
