The October 16, 2026 puzzle ran from a Velociraptor at 2 m to an Argentinosaurus at 33 m — about 17× apart, drawing on dinosaurs. The pair furthest apart was round 3: a Parasaurolophus is about 1.3× smaller than a Tyrannosaurus rex.
Answer: Allosaurus — 8.5 m. An Allosaurus measures 8.5 m (length / span), which is about 1.1× smaller than the reference, a Triceratops 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 Triceratops — big things get squeezed, small familiar things get stretched.
Answer: Argentinosaurus — 33 m. An Argentinosaurus measures 33 m (length / span), which is about 1.1× smaller than the reference, a Space Shuttle orbiter at 37.3 m.
Some estimates place this giant at more than 30 metres long.
Common miss: players tend to inflate an Argentinosaurus when it sits beside a Space Shuttle orbiter — big things get squeezed, small familiar things get stretched.
Answer: Parasaurolophus — 9.5 m. A Parasaurolophus measures 9.5 m (length / span), which is about 1.3× smaller than the reference, a Tyrannosaurus rex at 12.3 m.
The hollow head crest may have worked like a trumpet.
Common miss: players tend to inflate a Parasaurolophus when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: Velociraptor — 2 m. A Velociraptor measures 2 m (length / span), which is almost exactly the same size as the reference, a queen bed at 2 m.
Real Velociraptors were closer to turkey-sized than movie monsters.
Common miss: players tend to inflate a Velociraptor when it sits beside a queen bed — big things get squeezed, small familiar things get stretched.
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.
