So what extinct animals should we bring back? How about the giant cave bears or maybe the prehistoric elk?
The original American moose (replaced by its Asian cousin after the Pleistocene die-off)
The Irish Elk.
The Stellar Sea Cow hunted to extinction by early Russian explorers in Alaska.
The great auk (northern penguin)
Along with the latifrons bison above, these are a few of my pet choices for resurrection.
