Pleistocene deer were as large as moose and had even larger antler spreads.
Since they lived on a steepe-tundra grassland, they must have carried
several hundred lbs. of fat.  These were the most common form of deer in the
last two million years.

The Pleistocene extinction's that began with man's domestication of the dog,
seemed to have happened in order of fat content.
