Saber-toothed tigers, or machairodonts, were large, extinct cats known for their enormous upper canine teeth. These long, saber-like teeth were serrated and could reach up to 7 inches in length.
They had a robust, muscular build with powerful jaws and strong necks to support their fangs. Their fur was typically short and brownish, sometimes with spots or stripes. Some species grew over 10 feet long and weighed more than 500 pounds.
In addition to their famous teeth, they had long legs, powerful hindquarters, and sharp claws for gripping prey. They lived across forests, grasslands, and savannas in the Americas, Europe, and Asia until going extinct around 10,000 years ago.
