Smilodon

"Spearfang cat" is the informal name of a genus of large machairodontine cats that first appeared 3 million to 10,000 years ago in North and South America. When Europeans first settled in the New World, the spearfang cat was one of the most feared creatures they encountered. In the areas around the colonies, the cats were heavily hunted, with a bounty of 5 pounds per fang.
