A comet strike (actually seven) around 10,000 years ago caused global tsunami waves over 5Km high that flooded the entire continents of North and South America (and most of the world for that matter) wiping out most of the large mammals. (i.e. mastadons, giant sloths, sabertooth tigers, etc.) Many history books will tell you that it was around this same time that agriculture began, animals became domesticated, and civilizations popped up around the world. I believe it's more likely that all of these things restarted after the strike, the subsequent deluge, and the atomic winter that followed. This is the basis for many flood legends from around the world, not that of Noah however, his story originated from a comet strike localized to the mediteranean area a little over 5,000 years ago. Others have speculated that the lost city of Atlantis actually existed (perhaps not as gloriously as the survivors of the flood remember) but was drowned when the global sea levels rose after the comet strike 10,000 years ago. The strike sped up the melting of the last ice age and as the 2km thick layer of ice covering much of the Northern hemisphere melted, global sea levels rose dramatically swallowing up many ancient civilizations (i.e. underwater ruins in Japan, the Carribean) and of course covering the Grand Banks off of Newfoundland and changing the coastline of North America forever. Look at satelite images of the continent to get an idea of how much land was swallowed up as sea levels rose. My reccomendation is to read "Uriel's Machine" to explore this theory in more detail and discover many more substantiating facts.

Yes, an ox can kill a tiger if it was able to gore the tiger with its horns.
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!
