Prehistoric Farm brings paleontology and tycoon simulation together on Roblox, letting players sail across ancient islands, unearth fossils, and bring extinct beasts back to life. Developed by Project Mirvy, the game revolves around collecting complete fossil sets, exchanging them for eggs at Dr. Ivy's DNA Lab, and raising prehistoric creatures on a personalized ranch.

Whether you want to ride a swift raptor across the dunes or hatch an endgame apex predator, understanding how dinosaur management works is essential. This guide covers every documented dinosaur and prehistoric creature in Prehistoric Farm, how to obtain and hatch their eggs, and the exact care routines needed to raise them from tiny newborns into rideable elders.

Prehistoric Farm Dinosaurs and Creature List

Creatures in Prehistoric Farm span several distinct geological eras and rarity tiers. In-game dig sites and collection menus categorize discoveries by period: Cambrian, Devonian, Triassic, Jurassic, Cretaceous, and Cretaceous Seas. While early islands feature primordial organisms, later islands introduce legendary dinosaurs.

Community wikis document an economic progression where higher-rarity dinosaurs generate greater farm resource yields, require costlier fossil investments, and take longer to grow.

In addition to traditional land dinosaurs, the collection log features marine entries under Cretaceous Seas. Unlike terrestrial creatures, fan wikis note that these sea reptile eggs are acquired through open-water activities such as fishing rather than regular land excavations.

How to Get and Hatch Dinosaur Eggs

Every terrestrial dinosaur egg follows a strict multi-step restoration path. You cannot simply purchase living dinosaurs off a shelf; you must excavate their bones and incubate them yourself.

  1. Excavate Dig Sites: Sail to the island matching your target creature's period. Hold down your dig button on a mound and release when the indicator hits the green zone to secure a "Perfect" hit. Digs yield specific fossils, coins, buried treasure, or occasionally no fossil at all.
  2. Assemble a Complete Fossil Set: Check your fossil inventory. In observed Cambrian gameplay, sets required specific fossils from that period before the game displayed the "Ready to extract DNA" prompt.
  3. Trade with Dr. Ivy at the DNA Lab: Head back to the main home island. Speak with Dr. Ivy at her station and exchange your complete fossil set for a viable egg.
  4. Place the Egg in an Incubator: Take your egg to the incubation room. Players start with two unlocked incubator slots, with additional slots available for purchase.
  5. Wait Out the Incubation Timer: Hatching timers scale according to creature rarity. Recorded common and early eggs take between 1 minute and 5 minutes, while rare, epic, and legendary eggs scale up to 10 or 20 minutes.
  6. Collect at the Hatchery: When the timer reaches zero, walk over to the hatchery station to collect your hatched newborn, then place it inside a pen on your ranch.

Dinosaur Care: The Belly Rule and Growth Stages

Once you place a newly hatched creature on your ranch, it arrives as a fragile Newborn. According to official developer descriptions, creature growth relies on a single strict care mechanic: keep your dinosaur's belly over half full so it keeps growing.

How Feeding Works

  • Purchase Food: Buy supplies from the ranch food stall using coins earned from digging, treasure, and farm earnings.
  • Feed Manually: Approach your placed dinosaur with compatible food in hand to feed it.
  • Monitor the Half-Full Threshold: If your dinosaur's belly drops to 50% or below, growth halts immediately. Feeding it back above half full resumes development.
  • Check Dietary Needs: Herbivores require plant-based fodder, while carnivores require meat. Gameplay observations confirm meat-eaters can also consume certain player-caught ocean fish (such as mackerel or sardines).
  • Budget for Expansion: Upkeep costs scale as your farm expands. Feeding multiple mature dinosaurs requires a consistent coin reserve, so continue your excavation trips while raising young stock.

Growth Progression

Official documentation outlines the full progression from Newborn to Elder. Third-party guides divide this journey into five life stages: Newborn, Juvenile, Subadult, Adult, and Elder. As dinosaurs advance through these stages, their physical size expands, their economic resource production increases, and their interaction options broaden.

Riding Dinosaurs and Exploring Islands

Reaching maturity unlocks one of the most rewarding features in Prehistoric Farm: mounting and riding your dinosaurs.

  • Mount Requirements: Dinosaurs become rideable once they mature into their larger life stages. A prompt appears allowing you to hop onto your partner creature.
  • Mount Characteristics: Riding utility varies across species. Agile carnivores like the Velociraptor offer swift acceleration and nimble steering, making them ideal for navigating between island dig spots. Heavyweights like the T-Rex and Triceratops provide substantial stamina and steady ground coverage.
  • Exploration Utility: Riding mature dinosaurs helps players cross vast ranch pastures and island terrain much faster than traveling on foot.

Upgrades That Accelerate Your Dinosaur Farm

Progressing through higher-tier dinosaurs requires investing in tool and travel upgrades:

  • Shovel Tiers: Island dig sites are gated by shovel strength. The starting wooden shovel only works on Cambrian dig sites. Upgrading to the Bronze Shovel (observed at 2,500 coins) unlocks Devonian excavations, while advanced tiers like Silver, Iron, and Titanium open Triassic, Jurassic, and Cretaceous grounds.
  • Boat Upgrades: Sailing from the home island to remote dig sites requires seaworthy transport. Players can upgrade from the basic Dinghy to larger vessels like the Banks Dory (4,000 coins) or motorboats to reach distant islands faster.
  • Luck Potions and Clovers: Consumable items such as 2x Luck Potions or Lucky Clovers boost fossil extraction rates during dig runs, cutting down the time needed to finish rare sets.

Frequently Asked Questions

Why has my dinosaur stopped growing?

Under official game mechanics, a dinosaur only grows while its belly is more than half full. If growth stalls, buy compatible food from the stall and feed your creature until its fullness meter rises above 50%.

How long do dinosaur eggs take to hatch?

Hatch times depend on species rarity. Recorded early-game eggs take between 1 minute and 5 minutes. According to community documentation, uncommon eggs average around 2 minutes 30 seconds, rare eggs take 5 minutes, epic eggs take 10 minutes, and legendary eggs take up to 20 minutes unless sped up by boosts.

Which dinosaur is the best in Prehistoric Farm?

In community tier rankings, the Tyrannosaurus Rex and Spinosaurus rank highest (S-Tier) due to their unmatched endgame resource generation, large stature, and powerful riding presence. For mid-game progression, the Velociraptor is highly favored for its fast riding speed.

Can you ride every dinosaur immediately after hatching?

No. Freshly hatched creatures arrive as Newborns and cannot be mounted. You must feed them continuously until they reach their grown adult and elder stages before the riding prompt unlocks.
