A lost world.
A thousand questions.
Carry a little curiosity into a very big world. Meet remarkable dinosaurs, follow the traces they left, and find the stories waiting between them.

The world is open.
Eighteen painted regions. Every path is yours to follow.

These are original story settings. Fossil localities and ages belong to each dinosaur’s evidence record; a shared path does not mean the animals met.

Existing synthetic Peter narration. The 100 new fables are illustrated text stories; their narration is not recorded yet. Your listening position stays in this browser.
Small changes the meaning of big.
Put up to four dinosaurs on one shared ground plane. Metres and feet, together.
Lengths are rounded reconstruction estimates. The image transform preserves the calibrated body-length relationship; it does not make a fossil estimate exact. Unknown measurements remain unknown.
A world of questions.
A little film to open the door.
A five-minute journey through The Lost World’s paintings, evidence, stories and instruments.

The film is being prepared for this launch.
