Every creature, painted
From giant sauropods to feathered hunters
Each creature has its own painting, its size next to yours, where its fossils were found on a map of the ancient Earth, and a story to play, read aloud. All of it is in the app, so it works on a plane or in a tent.
- Fun facts with their sources, from museums and papers
- Maps of the continents as they were in each age
- Size compare, timelines and famous fossils












Hatch a mystery egg
Who's inside? Look for clues
Every few hours your egg gives a clue about who's inside. Guess who's inside, watch it crack open, and give your hatchling a name. Rarer eggs take longer, and twins can surprise you.
- Eggs painted for every kind of dinosaur and pterosaur
- Volcanic ash, earned by learning, warms an egg so it hatches sooner
- Badges bring reward eggs
Collect cards
A card for every creature, and rare full-art ones
Read about a creature to get its card, win it in a quiz, then hatch it for a glowing one. Cards come in six art styles, from crayon to pixel art, with stickers to decorate them. Full-art cards are the rarest of all: their paintings fill the whole card.
Meet Tiko
Ask Tiko the Troodon anything
Tiko knows every creature in the app. Ask a question, or chat with a dinosaur itself: it answers in its own voice, from what scientists know (and what they still argue about). The chat runs on Apple's on-device model, so nothing you type leaves your iPhone. Free-form chat needs a device with Apple Intelligence; on others, Tiko answers from the app's own pages.

Play
Play what you've learned
Nine kinds of quiz, from "Who's that shadow?" to myth busters and a speed round, and ten games: Dino Duel, Card Battle, a fossil dig, a pterosaur glide over the sea, jigsaws and more, alone or with someone next to you. Quizzes and games earn volcanic ash for your egg.
- Compare any two creatures, or a creature with you
- Find fossil sites and the museums that show them



Deep time
Five prehistoric ages, one story
Walk from the Permian, before the dinosaurs, through the Triassic, Jurassic and Cretaceous, to what came after. Each age has its painting, its map and its story, read aloud by a recorded voice, with bedtime stories of your own to make.
