Raise Animals Ancient Update (Cretaterra) — Codes, Biome

The Ancient Update in Raise Animals introduces a colossal new era of prehistoric creatures, mysterious eggs, and powerful upgrade systems. This guide breaks down everything you need to know about the Cretaterra biome, Dino Eggs, Incubation Pods, and more — so you can start breeding your own army of dinosaurs efficiently.

Cretaterra Biome

The new Cretaterra biome marks the game’s most ambitious expansion yet. It’s a volcanic, prehistoric world filled with molten landscapes, ancient fossils, and roaming dinosaurs.
To unlock the biome, progress through your main world until the “Ancient Rift” event appears — then step into the Cretaterra Portal.

Highlights:

• Distinct prehistoric terrain and visual effects
• Unique ambient sounds (meteor showers, distant roars)
• Dino Eggs appear as random falling events

2. New Animals — Complete Dino List

The update adds 10 prehistoric creatures, each tied to a rarity and incubation tier. These dinosaurs can be found through egg hatching, DNA upgrades, or Incubation Pods.

Rarity	Dinosaur	Notes
Basic	Gallimimus	Fast-moving herd dino; great for early fusion farming
Rare	Triceratops	Defensive herbivore; boosts DNA yield
Rare	Ankylosaurus	Tanky dino; resists weather penalties
Epic	Pterodactyl	First flying unit; earns bonuses during Meteor Falls
Epic	Brachiosaurus	Huge herbivore; massive coin multiplier
Legendary	Utahraptor	High speed; bonus fusion output
Legendary	Carnotaurus	Strong predator; boosts DNA during Prehistoric Storms
Rainbow	Spinosaurus	Semi-aquatic beast; top-tier egg dropper
Shine	Tyrannosaurus Rex	King of Cretaterra; multiplies rare egg spawn rate
Exclusive	Mosasaurus	Only hatchable via Tier 4–5 Pods; thrives during Bioluminescent weather

3. New Feature — Dino Egg Fall

How It Works

While exploring Cretaterra, you’ll occasionally see glowing Dino Eggs dropping from the sky. These eggs can be cracked open for rewards.

Drop Rates:

• 30% chance → Dino Egg (can hatch dinosaurs)
• 70% chance → Ruby (currency)

Tip: Use a high-tier incubator or fusion upgrades to maximize your egg hatching success. Egg rarity determines what dinosaur you might get.

4. Egg Fusion (DNA Upgrade System)

A brand-new system that lets you mutate and enhance your eggs.

How to Use Egg Fusion

1. Collect DNA Fragments from duplicate dinosaurs.
2. Head to the Egg Fusion Lab in Cretaterra.
3. Use DNA to upgrade your eggs — each level increases mutation rate.

Benefits

• Higher mutation = increased chance of rare or legendary dinos.
• You can fuse duplicates to raise mutation faster.
• Some dinos (like Utahraptor or Carnotaurus) boost fusion efficiency when active.

5. Incubation Pods — How to Hatch Dinosaurs

Incubation Pods are where you grow your eggs into dinosaurs. Each tier increases the chance of higher-rarity hatches.

Tier 1 — Basic Hatchery

• Gallimimus (80%)
• Triceratops (10%)
• Ankylosaurus (10%)

Tip: Great for farming DNA early on.

Tier 2 — Intermediate Hatchery

• Gallimimus (40%)
• Triceratops (20%)
• Ankylosaurus (20%)
• Pterodactyl (10%)
• Utahraptor (10%)

Tip: Start fusing DNA from Raptors here for faster mutation.

Tier 3 — Advanced Hatchery

• Triceratops (10%)
• Ankylosaurus (10%)
• Pterodactyl (25%)
• Utahraptor (25%)
• Brachiosaurus (15%)
• Carnotaurus (15%)

Tip: This tier introduces real balance — good mix of flyers, tanks, and predators.

Tier 4 — Elite Hatchery

• Brachiosaurus (15%)
• Carnotaurus (35%)
• Spinosaurus (40%)
• Mosasaurus (10%)

Tip: Save high DNA eggs for this tier. Spinosaurus becomes a Ruby generator.

Tier 5 — Apex Hatchery

• Spinosaurus (45%)
• Carnotaurus (40%)
• Mosasaurus (15%)

Tip: Focus on Bioluminescent weather for maximum yield when hatching here.

6. Weather Events — Boost Your Dino Profits

Cretaterra introduces dynamic weather with huge value multipliers.
Each event affects your dinosaur rewards and resource drops.

Weather	Bonus	Effect
Meteor Fall	+800% Value	Increases coin & DNA from all dinos
Prehistoric Storm	+1000% Value	Boosts Legendary hatching rate
Bioluminescent	+1200% Value	Doubles Ruby rewards and enhances Mosasaurus efficiency

Pro Tip: Save your eggs until Bioluminescent weather begins for maximum fusion results.

7. Redeem Codes (November 2025)

Use these new codes for exclusive rewards:

Code	Reward
Primordial	2500 💎
Jurassic	5x Daily Spin Wheel
Ancient	Mystery DNA Pack

Redeem codes via Menu → Settings → Codes section.

The Cretaterra Update transforms Raise Animals into a full-blown prehistoric simulation — combining DNA mechanics, mutation systems, and weather-driven value scaling. Whether you’re aiming to collect every dinosaur or maximize your fusion lab, this update rewards patience and smart timing.
