Triggering the Rift Event

How to Start a Prehistoric Invasion

Locate a deepslate or rusted copper laboratory structure in plains or desert biomes. Enter the facility and find the target block positioned between two signs. Apply redstone to this block to open a time rift.

Once activated, three escalating waves of dinosaurs and prehistoric flora will spawn into your world. Stronger creatures appear in later waves. Defeat enemies to collect rare dinosaur parts.

If the invasion becomes unmanageable, craft an Extinction Trigger using dinosaur drops and drop it on the ground to eliminate all spawned prehistoric mobs at once. This tool is essential for containment if you're building dinosaur enclosures away from your main base.
