Seasonal Buildings
Dinosaur Origin uses Fern Leaves and Cretaceous Scales to upgrade a seasonal building network. The Biotech Lab and Bio Greenhouses create the progression engine; Command Center, Armories, Fortifications, and Alliance Centers convert that progress into combat and alliance power.
Core rule
Do not rush combat structures before your resistance engine.
Command Center, Armory, and Fortification bonuses are useful, but they cannot replace access to stronger dinosaurs. Prioritize resistance and resource output until your account can reliably farm the levels you need.

What each structure contributes
Priority #1
Biotech Lab
Raises Virus Resistance and determines which dinosaur levels you can attack effectively.
Progression targetOnce level-60 dinosaurs are accessible, resistance upgrades become less mandatory.
Priority #2
Bio Greenhouses
Produce Fern Leaves, the primary seasonal construction resource. Four are available by default.
Best practiceBuild all four from the start and keep their levels reasonably balanced.
Damage
Command Center
Increases seasonal troop damage. Valuable after the Biotech Lab and Greenhouses are established.
TimingUpgrade after your resistance engine reaches a comfortable level.
Attack
Armory
Increases seasonal troop attack. Two can be built normally; a later combat unlock may allow a third.
BalanceDevelop alongside Fortification rather than creating a one-sided build.
Defense
Fortification
Increases seasonal troop defense. Two can be built and should support your Armory progression.
BalanceUse once resistance and production are no longer the immediate bottleneck.
Alliance
Alliance Centers
Required for Glory War and seasonal alliance development. Dinosaur Origin supports three themed Alliance Centers.
Alliance priorityPlace them as early as possible through coordinated teamwork.
Recommended Build Order
Resistance → Production → Alliance → Power
This order protects your ability to farm the season while still creating room for later combat specialization. The exact stopping point depends on which dinosaur levels your alliance expects members to handle.

Common mistake
Seasonal combat stats do not replace access to good targets.
A stronger formation still earns poor seasonal progression if Virus Resistance prevents it from attacking high-level dinosaurs. Build access first, then power.
