DAILY NO. 5 · VERIFIED MEASUREMENTS
The September 26, 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 5: a Brachiosaurus is 1.5× as big as a Spinosaurus.
Puzzle #5 asked about an Allosaurus, a Stegosaurus, a Pteranodon wingspan, a Diplodocus and a Brachiosaurus. 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: Allosaurus — 8.5 m. An Allosaurus measures 8.5 m (length / span), which is about 1.1× smaller than the reference, a Stegosaurus at 9 m.
The common large predator of its day: far more Allosaurus fossils exist than T. rex ones.
Common miss: players tend to inflate an Allosaurus when it sits beside a Stegosaurus — big things get squeezed, small familiar things get stretched.
Answer: Stegosaurus — 9 m. A Stegosaurus measures 9 m (length / span), which is about 1.4× smaller than the reference, a Tyrannosaurus rex at 12.3 m.
A brain the size of a lime, in a body as long as a bus.
Common miss: players tend to inflate a Stegosaurus when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: Pteranodon Wingspan — 6 m. 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.
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: Brachiosaurus — 22 m. A Brachiosaurus measures 22 m (length / span), which is 1.5× as big as the reference, a Spinosaurus at 15 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 Spinosaurus — big things get squeezed, small familiar things get stretched.
