About the dinosaurs game
How long was a Tyrannosaurus rex next to a bus, or a Velociraptor next to a person? Resize dinosaurs against familiar objects and animals and see how close your mental picture was.
Lengths are the Natural History Museum’s estimates from its Dino Directory. Fossil specimens vary, so treat each figure as a representative estimate rather than a record.

Common questions
Where do the dinosaur lengths come from?
From the Natural History Museum in London, which publishes an estimated length for each dinosaur in its Dino Directory.
Are the silhouettes accurate?
They are licensed reconstructions scaled so the measured length is correct; other proportions are illustrative.
Do dinosaurs appear in the daily challenge?
Yes, alongside other categories. This page adds a separate dinosaur set every day, played as practice so it does not affect your streak.
