DAILY NO. 49 · VERIFIED MEASUREMENTS
The November 9, 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 4: a Diplodocus is 2× as big as a Tyrannosaurus rex.
Puzzle #49 asked about a Pteranodon wingspan, a Parasaurolophus, a Tyrannosaurus rex, a Diplodocus and a Triceratops. Each answer below gives the measured size, the reference it stood beside and the source behind the number. Want the surprise first? Replay this puzzle — archived days never touch your streak.
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.
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 1.1× 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 2× as big as the reference, a Tyrannosaurus rex at 12.3 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 Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: Triceratops — 9 m. 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.
