220 prehistoric animal families

Build a collection. Grow a family.

Claim two new adults each day. Shuffle to meet an animal, then choose Collect & favorite to keep it. Daily claims reset at midnight UTC; repeat finds never use a claim.
Find its other half. Choose Find mate from a favorite in your collection. Collect both fictional variants, then choose Make a pair.
Care, then hatch. Three pair-care days produce an egg. Your first egg needs three care days; later eggs need ten. Check in once per calendar date. Missed days keep your progress.
Meet your baby companion. Hatches can be Common, Uncommon, Rare or Legendary. Keep its saved appearance, replay the hatch or open its animated browser companion.

Reading an exhibit saves no animal automatically. Play as a guest in this browser, or sign in to keep your collection across devices. Pairing, eggs and care are fictional game systems.

440 adult variants. 220 original baby rewards.
