ROUND 1
Allosaurus — 8.5 m
Answer: 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.
Answer: 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.
Answer: 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.
Answer: 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.
