The November 8, 2026 puzzle ran from an Allosaurus at 8.5 m to an Argentinosaurus at 33 m — about 4× apart, drawing on dinosaurs. The pair furthest apart was round 5: a Spinosaurus is 1.4× as big as an American school bus.
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: 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: 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 1.4× as big as the reference, an American school bus at 10.7 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 an American school bus — big things get squeezed, small familiar things get stretched.
