How Big Is Big?

 The largest dinosaur fossil - a human only reaches it's ankles.

The largest known dinosaur, Argentinosaurus huinculensis, weighed as much as 80 tons (160,000 pounds) and perhaps grew as long as 98 to 130 feet.

 

In comparison, the largest living mammal, the blue whale, can grow up to 111 feet long and weigh 200 tons (400,000 pounds).  It's heart is the size of a Volkswagen Beetle.

And size-wise, some things just don't make any sense at all.
