Sabertoothed tiger
The real scientific name for sabertoothed tigers of all ages was smilodon.

There were many kinds of sabertoothed cats, and they varied in size from that of a large house cat to that of a tiger or lion, and some were even bigger. The classic saber toothed "tiger" is called Smilodon and the South American species could weigh up to 500 kgs!
White tigers are not yet extinct. White tigers are also known as snow tigers. But no, they are not yet extinct, even. The white tigers are merely color variations of the Bengal tiger, extremely rare in the wild. They are not a different species from the Bengal, and white cubs can be born at any time in a litter of normal colored cubs. Also, the "snow" tiger is the Siberian tiger, not white Bengals.
sabertoothed tigers.
no
It has been speculated that the mass extinction of dinosaurs was caused by an asteriod, however there is not enough evidence collected to support this. It is still argued possible though.
Cats did not evolve from sabertoothed tigers. Rather, sabertoothed cats evolved from other cats. Modern apes evolved from miocene apes, which were somewhat similar. Miocene apes evolved from some lemur-like primate, or perhaps something like a lorise. http://en.wikipedia.org/wiki/Loris
A lot of people will say lion , however they are wrong because they are just stupid lion fans that know nothing about a tiger's advantages. The tiger will win because it is stronger! heavier, more agile, bigger, has longer canines, is a better fighter, is smarter, and is not lazy and waits for females to hunt. Tigers rule and lions are no sicken beans
The extiction of the dinosaurs made possible the expansion and rise of mammals.
Yes, you can help though.
