There were many different types Sabertoothed cats that lived at different time periods but the most popular one Smilodon lived in North America until the continent of South America colided with North America and they migrated across the border and settled down in South America also PS: (the continent of Pangaea started to break up around the Jurrasic period so the continents were pretty much as they were today. ).
The saber-toothed tiger - or more correctly - the saber-toothed cat is one of the most iconic mammals to have ever lived on this planet. However, you may be surprised to find out that there wasn't just one saber toothed cat. There is in fact there are over one hundred species and sub-species that can make claim to this title ranging from the extinct subfamilies of Machairodontinae (Felidae), Barbourofelidae (Feliformia), and Nimravidae (Feliformia).
There are also two families related to marsupials whose remains have been found worldwide. Depending on their species, saber-toothed tigers could weigh anywhere from a hundred pounds or so to more than 1,200 pounds putting them right at the top of the food chain. However, they have now been extinct for at least 11,000 years, believed to have been hunted by prehistoric humans.
It is also suggested that it was the end of the ice age which caused the extinction. Perhaps the most iconic of all the saber-toohed tigers is is the magnificent Smilodon, which itself is made up of three sub-species. In fact, if you combine the ranges of all the saber-toothed families together, their distribution would have once covered every continent in the world except Australia and Antarctica. This make it all the more tragic when you consider how such a successful group of animals managed to die out so completely!
