Answer: a Parasaurolophus measures 9.5 m (length / span), which is 1.1× as big as the reference, a Triceratops 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 Triceratops — big things get squeezed, small familiar things get stretched.
Answer: a Spinosaurus measures 15 m (length / span), which is 1.7× as big as the reference, a Stegosaurus at 9 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 Stegosaurus — big things get squeezed, small familiar things get stretched.
Answer: an Ankylosaurus measures 8 m (length / span), which is 1.7× as big as the reference, a family sedan at 4.6 m.
The tail club weighed tens of kilos and could swing hard enough to break bone.
Common miss: players tend to compress an Ankylosaurus when it sits beside a family sedan — big things get squeezed, small familiar things get stretched.
Answer: 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: an Allosaurus measures 8.5 m (length / span), which is about 1.4× smaller than the reference, a Tyrannosaurus rex at 12.3 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 Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
