How it works
Choose one of six Jurassic friends, then paint inside the outline with the brush — colors never spill outside the lines, so it is great for young kids. "Base color" fills the whole body underneath what you already painted, and the eraser turns areas back to white. When you press "Set free in the valley", your dinosaur marches out beneath the smoking volcano and every species moves its own way: the T-Rex stomps along heavily, the Triceratops trots proudly, the Stegosaurus and Brachiosaurus amble at their own slow pace, the Pteranodon soars across the sky, and the baby dino bounces around in its half-hatched egg. Dinos roam the whole valley — near the front, far by the palm trees, up and down the plain — so it feels deep and alive. Your own dinos never disappear while the page is open; the background is filled with recent drawings from other visitors around the world, which rotate over time. When you leave the page, your latest drawings are sent to the valley so other visitors can meet them too.
What we actually know about dinosaur colour
For most of the history of palaeontology, dinosaur colour was pure guesswork — which is why museum models kept changing from grey to green to brown as fashions shifted. That changed when researchers found melanosomes, the microscopic structures that hold pigment, preserved in some fossilised feathers. Their shape indicates the colour they produced, and a few species have now been reconstructed with real evidence: one small feathered dinosaur had a ginger-and-white striped tail.
For the giants, we still have almost nothing. Nobody knows what colour a T-Rex, a Brachiosaurus, a Stegosaurus or a Triceratops was, so a purple one is not less accurate than a grey one. Pteranodon was not a dinosaur at all but a flying reptile, and the baby dino hatching from the egg is a reminder that all of them started that size.
Colouring a creature nobody has seen
Look at living relatives. Birds are dinosaurs, and they are among the most colourful animals alive — bright feathers are not unrealistic.
Crocodiles and lizards suggest the other direction — mottled greens and browns that break up a large shape against foliage.
Give the stegosaurus plates a different colour from its body. Many palaeontologists think they were used for display, which would mean bright.
The triceratops frill is the same idea. A patterned frill on a plain body looks convincing and is easy to do.
Stripes on a long neck follow the shape and make the brachiosaurus read as tall rather than just large.
Life in the valley
Set free, each dinosaur moves in a way that suits its build. The brachiosaurus walks slowly with its long neck held high, the T-Rex strides on two legs, the triceratops and stegosaurus move heavily on four, and the pteranodon does not walk at all but circles overhead. The baby dino, freshly out of its egg, moves in short hurried steps.
The volcano in the background is scenery rather than a threat. Everything you create stays in the valley while the page is open, so it fills up as you colour more, and nothing is uploaded or stored anywhere — save any picture you want before closing the tab.
Yes. While you are on the page, your dinos roam only in your own valley. When you leave the page, your latest drawings are uploaded and appear as background dinos in other visitors' valleys. No name or personal information is attached — only the picture itself.
How long do background dinosaurs stay?
Background dinos from other visitors rotate every few minutes so the valley always feels fresh. Your own dinos are different: they never expire while the page stays open.
Is this safe for kids?
Yes — there is no free drawing, no text, no chat and no user names. Children can only color inside fixed dinosaur outlines, so nothing inappropriate can be created or shared.
Can I save my dinosaur as an image?
Yes — press "Save picture" to download your colored dinosaur as a PNG image, ready for printing or sharing.
What color were real dinosaurs?
For most species nobody knows — skin color rarely survives fossilization, so the greens and browns in books are educated guesses. A few exceptionally preserved fossils changed that: researchers found fossilized pigment structures called melanosomes showing, for example, that Sinosauropteryx had a reddish striped tail. So your color choices are as valid as anyone's.
Is the Pteranodon actually a dinosaur?
Strictly speaking, no — Pteranodon was a pterosaur, a flying reptile that lived alongside dinosaurs but belonged to a separate group. Real dinosaurs walked with their legs held directly under their bodies, and none of the classic ones flew. Pterosaurs are still honorary members of every dino collection, which is why one soars over this valley.
