The November 3, 2026 puzzle ran from a Parasaurolophus at 9.5 m to an Argentinosaurus at 33 m — about 3× apart, drawing on dinosaurs. The pair furthest apart was round 5: a Tyrannosaurus rex is 1.4× as big as a Stegosaurus.
Answer: Brachiosaurus — 22 m. A Brachiosaurus measures 22 m (length / span), which is about 1.1× smaller than the reference, a Diplodocus at 25 m.
Brachiosaurus held its neck upward, making it far taller than long-tailed sauropods of similar length.
Common miss: players tend to inflate a Brachiosaurus when it sits beside a Diplodocus — big things get squeezed, small familiar things get stretched.
Answer: Diplodocus — 25 m. A Diplodocus measures 25 m (length / span), which is 1.1× as big as the reference, a Brachiosaurus at 22 m.
Almost half of Diplodocus was tail, which may have cracked like a whip.
Common miss: players tend to compress a Diplodocus when it sits beside a Brachiosaurus — big things get squeezed, small familiar things get stretched.
Answer: Argentinosaurus — 33 m. An Argentinosaurus measures 33 m (length / span), which is about 1.1× smaller than the reference, a Space Shuttle orbiter at 37.3 m.
Some estimates place this giant at more than 30 metres long.
Common miss: players tend to inflate an Argentinosaurus when it sits beside a Space Shuttle orbiter — big things get squeezed, small familiar things get stretched.
Answer: Parasaurolophus — 9.5 m. A Parasaurolophus measures 9.5 m (length / span), which is 1.1× as big as the reference, a Triceratops at 9 m.
The hollow head crest may have worked like a trumpet.
Common miss: players tend to compress a Parasaurolophus when it sits beside a Triceratops — big things get squeezed, small familiar things get stretched.
Answer: Tyrannosaurus rex — 12.3 m. A Tyrannosaurus rex measures 12.3 m (length / span), which is 1.4× as big as the reference, a Stegosaurus at 9 m.
A large T. rex reached around 12.3 metres long.
Common miss: players tend to compress a Tyrannosaurus rex when it sits beside a Stegosaurus — big things get squeezed, small familiar things get stretched.
