ROUND 1
Diplodocus — 25 m
Answer: a Diplodocus measures 25 m (length / span), which is 1.1× as big as the reference, a Brachiosaurus at 22 m.
Almost half of Diplodocus was tail, which may have cracked like a whip.
Common miss: players tend to compress a Diplodocus when it sits beside a Brachiosaurus — 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 Stegosaurus 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 Stegosaurus — big things get squeezed, small familiar things get stretched.
Answer: a Velociraptor measures 2 m (length / span), which is about 1.1× smaller than the reference, a three-seat sofa at 2.2 m.
Real Velociraptors were closer to turkey-sized than movie monsters.
Common miss: players tend to inflate a Velociraptor when it sits beside a three-seat sofa — big things get squeezed, small familiar things get stretched.
Answer: an Argentinosaurus measures 33 m (length / span), which is about 2.1× smaller than the reference, a Boeing 747 at 70.7 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 Boeing 747 — big things get squeezed, small familiar things get stretched.
