The September 23, 2026 puzzle ran from a Velociraptor at 2 m to a Triceratops at 9 m — about 5× apart, drawing on dinosaurs. The pair furthest apart was round 3: an Allosaurus is about 1.3× smaller than an American school bus.
Puzzle #2 asked about a Triceratops, a Pteranodon wingspan, an Allosaurus, a Velociraptor 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 a Triceratops compared with a Stegosaurus?
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.
How wide is a Pteranodon wingspan compared with an American pickup truck?
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.
How long is an Allosaurus compared with an American school bus?
Answer: Allosaurus — 8.5 m. An Allosaurus measures 8.5 m (length / span), which is about 1.3× smaller than the reference, an American school bus at 10.7 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 an American school bus — big things get squeezed, small familiar things get stretched.
