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 Spinosaurus measures 15 m (length / span), which is 1.2× as big as the reference, a Tyrannosaurus rex at 12.3 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 a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: a Triceratops measures 9 m (length / span), which is about 1.2× smaller than the reference, an American school bus at 10.7 m.
The skull alone could reach 2.5 m, among the largest of any land animal.
Common miss: players tend to inflate a Triceratops when it sits beside an American school bus — big things get squeezed, small familiar things get stretched.
Answer: a Parasaurolophus measures 9.5 m (length / span), which is 1.1× as big as the reference, a Stegosaurus at 9 m.
The hollow head crest may have worked like a trumpet.
Common miss: players tend to compress a Parasaurolophus 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 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.
