Seasonal Resources
Fern Leaves and Cretaceous Scales upgrade seasonal buildings. Ancient Dino Eggs power the Bio Institute Shop, Dino Feed and Pine Cones raise your chosen dinosaur, Fossils complete the album, and Glory Points drive badge progression.
Core rule
Fern Leaves and Cretaceous Scales are the building engine.
Other currencies unlock valuable rewards, but these two resources control seasonal construction. Falling behind on either slows the Biotech Lab, Greenhouses, combat structures, and Alliance Center development.

What each seasonal currency does
Core
Fern Leaves
Produced by Bio Greenhouses and used as the primary material for seasonal building upgrades.
Best practiceBuild all four Greenhouses at the beginning of the season.
Core
Cretaceous Scales
Earned by defeating map NPCs. Scales are the secondary building resource and are just as necessary as Fern Leaves.
Best sourceVelociraptors and other seasonal NPC activity.
Shop
Ancient Dino Eggs
Earned from Stegosauruses, Predator Squads, events, and duplicate Fossils. Used in the weekend Bio Institute Shop.
Shop accessSaturday and Sunday, with limited refreshes.
Hatch
Dino Feed & Pine Cones
Used to raise the dinosaur selected through Hatch of Legends. Earned through tasks and seasonal NPC kills.
LimitYou select one dinosaur species for the season.
Collection
Fossils
Twenty unique Fossils form the Fossil Album. Duplicates can be exchanged for Ancient Dino Eggs.
Main sourceAncient Dino participation rewards.
Progress
Glory Points & Badges
Dinosaur kills generate Glory. Collect a Glory Chest every eight hours to turn progression into seasonal badges.
Key principleHigher-level dinosaurs produce faster Glory progress.
Resource Planning
Separate building resources from reward currencies.
Fern Leaves and Scales should serve your progression engine first. Eggs, Fossils, Feed, Pine Cones, and Badges support shops, collections, and long-term bonuses. Treating every currency as interchangeable leads to poor priorities.
✓Collect Greenhouses before they cap.
✓Plan Eggs around the weekend shop.
✓Exchange duplicate Fossils instead of ignoring them.
✓Claim Glory Chests on schedule.
Common mistake
Do not neglect Scales while waiting on Fern Leaves.
Seasonal upgrades require both resource streams. Strong Greenhouse production cannot compensate for weak NPC farming, and heavy farming cannot compensate for idle Greenhouses.
