ROUND 1
Triceratops — 9 m
Answer: a Triceratops measures 9 m (length / span), which is almost exactly the same size as the reference, a Stegosaurus at 9 m.
The skull alone could reach 2.5 m, among the largest of any land animal.
Common miss: players tend to inflate a Triceratops when it sits beside a Stegosaurus — big things get squeezed, small familiar things get stretched.
Answer: a Brachiosaurus measures 22 m (length / span), which is 1.2× as big as the reference, a rescue helicopter at 17.8 m.
Brachiosaurus held its neck upward, making it far taller than long-tailed sauropods of similar length.
Common miss: players tend to compress a Brachiosaurus when it sits beside a rescue helicopter — big things get squeezed, small familiar things get stretched.
Answer: a Pteranodon wingspan measures 6 m (length / span), which is 1.3× as big as the reference, a family sedan at 4.6 m.
Measured across the wings — a span no living bird comes close to.
Common miss: players tend to compress a Pteranodon wingspan when it sits beside a family sedan — big things get squeezed, small familiar things get stretched.
