10 Amazing Big Cats From Prehistory Some Of Which You May Not Have Heard Of
Before human beings, Felidae, or cats, were the most successful, powerful predators in most of the world. Even today, big cats such as tigers, lions, jaguars and leopards keep causing admiration and fear, but these magnificent beasts are dwarfed by some of their extinct relatives.
Here are prehistory’s largest, mightiest cats, some of which were seen by humans only a few thousand years ago.
1- Giant Cheetah The Giant Cheetah (Acinonyx pardinensis), belonged to the same genus as modern day Cheetah (Acinonyx jubatus), and probably looked very similar, but it was much bigger.
2- Xenosmilus hodsonae Xenosmilus hodsonae is a relative to Smilodon (“saber-toothed tiger”), but instead of having long, blade-like fangs, it had shorter and thicker teeth.
3- Giant Jaguar In prehistoric times, both North and South America were home to gigantic jaguars, belonging to the same species as modern day jaguars (Panthera onca) but much bigger.
4- European Jaguar It was a huge predator, weighing up to 210 Kgs (463) or more, and probably at the top of the food chain in Europe, 1.5 million years ago. Its fossil remains have been found in Germany, France, England, Spain and the Netherlands.
5- Cave Lion The Cave lion was a gigantic subspecies of lion, weighing up to 300 kgs (661lbs) or more (and therefore, being as large as the Amur or Siberian tiger, the largest cat of our days.
6- Homotherium serum Also known as the “Scimitar cat”, Homotherium serum was one of the most successful felines in prehistoric times, being found in North and South America, Europe, Asia and Africa.
7- Machairodus aphanistus Machairodus aphanistus probably looked pretty much like a gigantic tiger with saber teeth; it had very tiger-like proportions and a long tail, although it is impossible to know if it had stripes, spots or any other kind of fur markings.
8- American Lion The American lion or Panthera atrox, is probably the best known of all prehistoric cats after Smilodon. It lived in both North and South America (from Alaska to Peru) during the Pleistocene epoch, and went extinct 11,000 years ago, at the end of the last Ice Age.
9- Pleistocene Tiger The most obscure cat in the list, being known from fragmentary remains which have yet to be formally described. Most likely “Pleistocene tiger” is not a separate species, but rather the “early version” of the same tigers we see today. It is also known as Ngandong tiger.
10- Smilodon Smilodon is one of the most famous prehistoric predators, and also one of the most formidable. There were at least three species living in both North and South America; the smallest species, Smilodon gracilis, was about the size of a modern day jaguar, while Smilodon fatalis was as big as a lion.
