DAILY NO. 22 · VERIFIED MEASUREMENTS
The five dinosaurs objects from the Size It Up puzzle on October 13, 2026, with the measured size of each, the reference it was compared against, a source you can check, and how the community's guesses landed. Want the surprise first? Replay this puzzle — archived days never touch your streak.
The October 13, 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 Spinosaurus is 1.2× as big as a Tyrannosaurus rex.
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: 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: Triceratops — 9 m. A Triceratops measures 9 m (length / span), which is 1.1× as big as the reference, an Ankylosaurus at 8 m.
The skull alone could reach 2.5 m, among the largest of any land animal.
Common miss: players tend to compress a Triceratops when it sits beside an Ankylosaurus — big things get squeezed, small familiar things get stretched.
Answer: Spinosaurus — 15 m. A Spinosaurus measures 15 m (length / span), which is 1.2× as big as the reference, a Tyrannosaurus rex at 12.3 m.
The longest predatory dinosaur known, and probably one that spent much of its life in water.
Common miss: players tend to compress a Spinosaurus when it sits beside a Tyrannosaurus rex — 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.
