How to unlock Prehistoric
The gate is 17M Speed. Speed comes from rebirths and from the pets you keep running, so the way through it is the rebirth loop rather than a single purchase. The collection before it in the ladder is Abyss Ocean, at 2.5M Speed. The next gate after it is Cosmic, at 700M Speed.
Hatching happens on the map, so a pet from this collection is only reachable from a run that has already opened it. " That is the reason the ladder order matters more than raw playtime: a run parked below the gate cannot reach the pets above it.
What is not published
This site does not print hatch odds, drop rates, spawn rules or trade prices for Prehistoric: none of those are published anywhere it could verify, and copying them from an unverifiable source would make the table wrong rather than useful. Egg and source names for individual pets are also left open — the site does not turn a collection name into an egg name. What is published here is the part it can stand behind: the gate, the guardian, the pet list and the reference values.
