Dino Strata

Tap the rock face, crack the strata, and lift a real fossil into the light. Dino Strata is an idle excavation game about digging down through geological time. Your strikes break the layer in front of you; the dig team you hire keeps working while you are away. Every fossil you unearth is a real prehistoric animal, painted in watercolour and filed in a fossil log with its scientific name, period and locality. ■ Dig, hire, descend Break a layer, earn Excavation Points, and spend them on your pick and on a dig team of 33 specialists who excavate on their own. When a run has gone as deep as it can, descend through time: the run resets, but the Specimen Value you have appraised makes every future dig permanently faster. Deeper always means older. ■ 100 real prehistoric species Tyrannosaurus, Stegosaurus, Anomalocaris, the woolly mammoth, and 96 more. Every entry carries its scientific name, period, age in millions of years, locality, approximate length, and a note on how firm the restoration actually is. ■ A fossil log across nine eras The log is a grid of nine geological bands, from the Early Paleozoic to the Quaternary. Undiscovered species stay in silhouette; the deeper you dig, the older the band you open. Rarity runs Common, Rare, Super Rare, Ultra Rare - and the rarer the find, the longer the reveal lingers. ■ Idle that actually idles This is the part most tap-and-dig games leave hollow. Your team keeps clearing layers while the app is closed, up to 8 hours, and the reward waiting for you is unconditional, immediate, and yours without watching anything. An ad only doubles it. It is never required. ■ Ads are optional, always Rewarded video only. No banners, no forced interstitials, nothing that interrupts a dig. The reward is a fixed amount and is granted only when the video finishes. Everything in the game can be reached without watching a single one. ■ No gacha. No loot boxes. No subscription. Excavation Points cannot be bought. The fossils you unearth are random, but the points that pay for the dig come only from playing and from optional ads, so there is no path from real money to a random result. Nothing with a randomised outcome is ever sold. ■ Premium (one-time) One non-consumable purchase: it removes ads, extends offline progress from 8 hours to 24, and adds auto-dig so your hand can rest. That is all it does, and it is permanent. Restore Purchases is supported. Nothing is ever put back behind a second paywall. ■ Built to be kept Progress is saved on device and can be backed up to and restored from iCloud, because losing an idle save is unforgivable. Reduce Motion, Dynamic Type, numbers written to be read aloud, rarity shown by frame shape and star count rather than colour alone, and a layout you can reach one-handed. ■ Honest notes - The fossil restorations are illustrations made with generative AI. They are original watercolour art, not photographs, and not to scale. - Every species is real. Scientific names, periods and localities come from the Paleobiology Database (CC BY 4.0); body length and diet are editorial estimates and are marked as such in the app. - Restorations are interpretations. Where the science has not settled, the entry says so. The Paleobiology Database attribution (CC BY 4.0) is shown in Settings > About and on every fossil entry.
