How to get Pterodactyl
Train until you have at least 17M – 18M Speed, then go to Prehistoric, zone 8 of 14, guarded by the T-Rex. Steal eggs there and bring them back to your base to hatch.
Each egg that spawns in Prehistoric has a 26.044039% chance to be a Pterodactyl Egg. That means you need to see about 3 eggs for a 50% chance of at least one, and 8 eggs for 90%.
A Pterodactyl egg takes 3m to hatch, and the wiki lists its reward as +270k Speed, $2.2m.
