The September 22, 2026 puzzle ran from a Velociraptor at 2 m to a Parasaurolophus at 9.5 m — about 5× apart, drawing on dinosaurs. The pair furthest apart was round 2: a Pteranodon wingspan is about 1.5× smaller than a Triceratops.
Puzzle #1 asked about an Allosaurus, a Pteranodon wingspan, a Velociraptor, a Parasaurolophus and an Ankylosaurus. 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.
ROUND 1
How long is an Allosaurus compared with an Ankylosaurus?
Answer: Allosaurus — 8.5 m. An Allosaurus measures 8.5 m (length / span), which is 1.1× as big as the reference, an Ankylosaurus at 8 m.
The common large predator of its day: far more Allosaurus fossils exist than T. rex ones.
Common miss: players tend to compress an Allosaurus when it sits beside an Ankylosaurus — big things get squeezed, small familiar things get stretched.
How wide is a Pteranodon wingspan compared with a Triceratops?
Answer: Pteranodon Wingspan — 6 m. A Pteranodon wingspan measures 6 m (length / span), which is about 1.5× smaller than the reference, a Triceratops at 9 m.
Measured across the wings — a span no living bird comes close to.
Common miss: players tend to inflate a Pteranodon wingspan when it sits beside a Triceratops — big things get squeezed, small familiar things get stretched.
How long is a Velociraptor compared with a road bicycle?
Answer: Velociraptor — 2 m. A Velociraptor measures 2 m (length / span), which is 1.1× as big as the reference, a road bicycle at 1.8 m.
Real Velociraptors were closer to turkey-sized than movie monsters.
Common miss: players tend to compress a Velociraptor when it sits beside a road bicycle — big things get squeezed, small familiar things get stretched.
How long is a Parasaurolophus compared with an American school bus?
Answer: Parasaurolophus — 9.5 m. A Parasaurolophus measures 9.5 m (length / span), which is about 1.1× smaller than the reference, an American school bus at 10.7 m.
The hollow head crest may have worked like a trumpet.
Common miss: players tend to inflate a Parasaurolophus when it sits beside an American school bus — big things get squeezed, small familiar things get stretched.
