Once Upon A Time, Size Mattered

Once Upon A Time, Size Mattered

During the Cenozoic era, size did matter.

 

The age of the mammals began at the end of the Cretaceous period 65 million years ago with the extinction of the dinosaurs that kick-started our own evolution. If you were a typical human in that ancient era walking the hills, plains, and valleys then, how would you compare to an elephant bird, a giant sloth, or a cave bear? In physical size, we would be relatively minor mammals in comparison to those huge beasts and many others. It's a wonder we survived and prospered, likely at the expense of these extinct beasts, instead of just becoming fossils ourselves.  WHB
