A free dinosaur mod for 1.20.1 and 1.21.1, inspired by the classic JurassiCraft experience – no paywalls, no nonsense.
📦 About the Mod:
Jurassic Revived is a fan-made dinosaur mod for Minecraft 1.20.1 and 1.21.1, inspired by the gameplay and features of the original JurassiCraft mod.
🧬 Core Features:
-
🦴 Fossil & DNA System Dig up fossils, extract DNA, and bring dinosaurs back to life using high-tech machines.
-
🧠 Dynamic Dinosaur AI Species-specific behaviors such as aggression, fleeing, roaming, and herding.
-
🏞️ Park-Building Tools Create enclosures, labs, research zones, and viewing areas.
💡 Why Jurassic Revived?
When JurassiCraft went private and its downloads disappeared, this mod was made to continue the legacy — for the community, by the community. Jurassic Revived offers the same immersive dinosaur gameplay — without restrictions.
⚠️ Disclaimer: This is a fan project and is not affiliated with the newer JurassiCraft team (everything that appears in this mod comes either from the assets that the former team members have provided us with or was directly created by us) or any associated franchises. The mod is non-commercial and only inspired by the legacy of JurassiCraft.

This update got big enough that it became difficult to track the changes, so there are many more micro changes and fixes, but this list should cover the majority of what was changed.

This version is a complete rewrite from the ground up! There are some slight differences and places where we are lacking, but other new features should fill the void.
<span style="color:#E03E2D;">THIS VERSION IS NOT A DROP IN REPLACEMENT WITH OLDER VERSIONS. YOU WILL LOSE YOUR DATA IF YOU UPDATE</span>
- Notable Changes:**
- 1.21.1 Support!
- JEI Support!
- 33 Dinos!
- Reworked textures, models, animations
- New GUIs
- New machine logic and an optional power requirement
- Reworked the animation system to allow concurrent animations
- Fancy code to make the tails flow when turning
- Adjusted entities to (hopefully) not spin, regardless of size
- Steps back:**
- No sounds (we are hard at work implementing this system, and should be here the next update)
- Pteranodon missing (We made the decision to not bring the Pteranodon over, moving him to his own update with several other avian creatures for a themed update in the future)
- Jeep missing (As the systems weren't in place, we removed the Jeep, which will be returning in the locomotive update, including more than just the jeep)
From here on out, updates should be more often, not as impactful, and be more feature rich. Ownership and development of the mod has had some drastic changes, constituting a split with a former owner who attempted to sabotage the mod. We are still considering supporting fabric for at least one of the current versions, but have not made the decision one way or another. We are also considering what versions we will be supporting in the future.
