Answer: a Brachiosaurus measures 22 m (length / span), which is 1.5× as big as the reference, a Spinosaurus at 15 m.
Brachiosaurus held its neck upward, making it far taller than long-tailed sauropods of similar length.
Common miss: players tend to compress a Brachiosaurus when it sits beside a Spinosaurus — 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 Iguanodon measures 10 m (length / span), which is 1.1× as big as the reference, a Triceratops at 9 m.
Its thumb spike was first reconstructed, wrongly, as a horn on the nose.
Common miss: players tend to compress an Iguanodon when it sits beside a Triceratops — big things get squeezed, small familiar things get stretched.
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 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.
