The November 4, 2026 puzzle ran from a Pteranodon wingspan at 6 m to a Diplodocus at 25 m — about 4× apart, drawing on dinosaurs. The pair furthest apart was round 3: a Brachiosaurus is 1.8× as big as a Tyrannosaurus rex.
Answer: Tyrannosaurus rex — 12.3 m. A Tyrannosaurus rex measures 12.3 m (length / span), which is 1.1× as big as the reference, an American school bus at 10.7 m.
A large T. rex reached around 12.3 metres long.
Common miss: players tend to compress a Tyrannosaurus rex when it sits beside an American school bus — big things get squeezed, small familiar things get stretched.
Answer: Diplodocus — 25 m. A Diplodocus measures 25 m (length / span), which is almost exactly the same size as the reference, a blue whale at 25 m.
Almost half of Diplodocus was tail, which may have cracked like a whip.
Common miss: players tend to inflate a Diplodocus when it sits beside a blue whale — big things get squeezed, small familiar things get stretched.
Answer: Brachiosaurus — 22 m. A Brachiosaurus measures 22 m (length / span), which is 1.8× as big as the reference, a Tyrannosaurus rex at 12.3 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 Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: Ankylosaurus — 8 m. An Ankylosaurus measures 8 m (length / span), which is about 1.1× smaller than the reference, a Triceratops at 9 m.
The tail club weighed tens of kilos and could swing hard enough to break bone.
Common miss: players tend to inflate an Ankylosaurus when it sits beside a Triceratops — big things get squeezed, small familiar things get stretched.
Answer: Pteranodon Wingspan — 6 m. A Pteranodon wingspan measures 6 m (length / span), which is almost exactly the same size as the reference, an American pickup truck at 5.9 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 an American pickup truck — big things get squeezed, small familiar things get stretched.
