How to get
Where this pet comes from.
Hatch Pterodactyl Egg in the Prehistoric biome — you need 17,000,000 Speed to enter (train on your treadmill).
Eggs spawn at biome nests and reset every in-game night (4:30). Larger, more exotic egg variants have better odds at rare pets. Watch out for the T-Rex guarding the area.

FAQ
How much income does Pterodactyl give in Steal An Egg?
Pterodactyl's documented base rate is $22K per second. Applying the documented mutation scalars gives $44K/s for Golden, $110K/s for Rainbow, and $132K/s for Golden + Rainbow (mutation bonuses add above the base ×1 rather than multiplying); those scalars are not developer-published values.
How do you get Pterodactyl?
Hatch Pterodactyl Egg in the Prehistoric biome (requires 17,000,000 Speed). Eggs spawn at nests and reset every in-game night (4.5 minutes).
What rarity is Pterodactyl?
Pterodactyl is Legendary.
How do mutations affect Pterodactyl's income?
Mutations stack additively on top of Pterodactyl's documented base rate: Mutation Factor = 1 + Σ(Scalar − 1), so Golden + Rainbow gives ×6, not ×10. The pet's weight adds a nonlinear size factor on top: scale = ∛(pet weight ÷ 180 kg), the species' documented reference weight. The official game page confirms mutations exist, but this site has no developer-published multiplier table, so treat every scalar as a sourced estimate rather than an official guarantee.
Is Pterodactyl currently obtainable?
Pterodactyl is marked obtainable in the current data snapshot. Availability can change with game events, so check the listed biome or egg pool in-game before farming.
