Tree Tumbo

It is considered a living fossil found in the deserts of Namibia and Angola. Thats not enough for this countdown though. It is unique in that it has one very short trunk and grows two leaves (only two) from the trunk no matter how mature it is. Oh yeah, and carbon dating tells us that theyre anywhere from 500-2000 years old (and maybe older). So the one pictured to the right will probably be alive when your great-great-great grand kids are alive. That is assuming no apocalypses happen, although Id bet these guys know how to survive much better than we do.
