Answer: an Allosaurus measures 8.5 m (length / span), which is about 1.1× smaller than the reference, a Triceratops at 9 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 Triceratops — big things get squeezed, small familiar things get stretched.
Answer: a Brachiosaurus measures 22 m (length / span), which is 2.1× as big as the reference, an American school bus at 10.7 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 an American school bus — 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.
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 Triceratops measures 9 m (length / span), which is about 1.4× smaller than the reference, a Tyrannosaurus rex at 12.3 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 Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
