Welcome to Dinosaurium — your personal prehistoric sanctuary built from sun-warmed cliffs, mossy ferns, and ancient riverbeds. Discover, care for, and grow over 500 unique dinosaur species across nine richly themed prehistoric habitats.

With a single click, your dinosaurs leave the habitat and roam freely across your real desktop — characterful, transparent companions striding over your windows while you work, study, or browse. They never get in the way: clicks pass right through them, and a tap of ESC sends them home. Your living collection, alive on your screen.

Build the ultimate dinosaur library across nine themed packs — Theropods, Tyrants, Raptors, Sauropods, Ceratopsians, Armored, Marine Reptiles, Pterosaurs, and more. Each species is assigned one of seven rarity tiers — from Common to Ancient. Unlock stunning visual variants: Normal, Painted, Golden, and Rainbow. From tiny feathered hunters to towering long-necks, complete your collection one fossil at a time.

Witness prehistory come alive in real time. Eggs hatch into tiny hatchlings that wobble through your habitat. Watch them grow into magnificent adults — raptors darting through the ferns, sauropods stretching their necks to the canopy, tyrants striding across the plains. Release them for instant rewards, or keep them in your habitat for steady passive income. Every decision shapes your strategy.

Your prehistoric park keeps thriving in the background while you work, study, or browse the web. The automatic feeding system keeps your dinosaurs happy and fed; when you return, gathered rewards are waiting. No pressure, no timers — just progress at your own pace.

Choose from cliffs, ferns, volcanoes, decorations, and day-night lighting cycles. Customize multiple habitats exactly the way you want. Build a lush jungle valley, a sun-baked desert ridge, or a misty marine cove — this is your sanctuary, your rules.

Climb the rankings by total collection value or by the number of unique species you've discovered. See how your prehistoric park measures up against dinosaur keepers worldwide.
