What's gone extinct: Virtually all of South America's marsupial megafauna (much of this prior to the arrival of humans, triggered by the rising of the central American ithsmus), mammoths, mastodons, native horses (the species was reintroduced by Europeans), giant ground sloth (Megalonyx), short-faced bears, saber-toothed cats, dire wolves, tapirs, peccaries, giant tortoises, the American lion, Miracinonyx (the American cheetah), siaga antelope, several species of llamas, Camelops (a giant camel), and more, all in North America alone. Very nearly the American bison ("buffalo") and California condor, amongst others.
In Europe there were also several species of mammoth and mastodons, native straight-tusked elephants, lions, cave bear, Irish elk, woolly rhinocerous, aurochs, and more.
Australia saw two phases of human-driven extinctions, one triggered by the aboriginies roughly 50kya, the second by Europeans, beginning about 250 years ago.

It was about what has survived
Large land animals only really survive in Africa
This is a very cool idea; I haven't heard of it before, and I'm not finding much on this concept on the 'web.
Anything you can point me to? :)
