Saber Tooth Tigers

Saber tooth tigers lived many, many years ago back when the earth was trapped in an Ice Age. At that time, woolly mammoths and mastodons roamed the icy land. Smilodons, which were a type of saber tooth tiger, were a tiny bit smaller than the panthers that live today. However, smilodons were heavier than panthers, weighing a whopping 440 lbs. The smilodons were the biggest kind of saber tooth. Saber tooths were very fierce predators. The saber tooth tiger was about the size of the African lion. Some saber tooth tigers grew up to 15 feet in length!
