How much bigger is a bison than a human?

Small dinosaurs were much smaller than humans. Epidexipteryx was only 9.8 inches long and weighed a few ounces. The largest well known dinosaur, Argentinosaurus, was 100 to 115 feet long and weighed 50 to 73 tons. That's as long as 19 men laying end to end, and as heavy as 975 people!
