Answer: a Triceratops measures 9 m (length / span), which is almost exactly the same size as the reference, a Stegosaurus at 9 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 a Stegosaurus — big things get squeezed, small familiar things get stretched.
Answer: a Pteranodon wingspan measures 6 m (length / span), which is almost exactly the same size as the reference, an American pickup truck at 5.9 m.
Measured across the wings — a span no living bird comes close to.
Common miss: players tend to compress a Pteranodon wingspan when it sits beside an American pickup truck — big things get squeezed, small familiar things get stretched.
Answer: an Argentinosaurus measures 33 m (length / span), which is 1.5× as big as the reference, a Brachiosaurus at 22 m.
Some estimates place this giant at more than 30 metres long.
Common miss: players tend to compress an Argentinosaurus when it sits beside a Brachiosaurus — big things get squeezed, small familiar things get stretched.
Answer: a Stegosaurus measures 9 m (length / span), which is about 1.4× smaller than the reference, a Tyrannosaurus rex at 12.3 m.
A brain the size of a lime, in a body as long as a bus.
Common miss: players tend to inflate a Stegosaurus when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: an Ankylosaurus measures 8 m (length / span), which is about 1.1× smaller than the reference, a Triceratops at 9 m.
The tail club weighed tens of kilos and could swing hard enough to break bone.
Common miss: players tend to inflate an Ankylosaurus when it sits beside a Triceratops — big things get squeezed, small familiar things get stretched.
