10 Huge Prehistoric Cats
Before man became a hunter and made his way to the top of the food chain, the 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. I give you ten of prehistory’s largest, mightiest cats, some of which were seen by humans only a few thousand years ago.
The Giant Cheetah (Acinonyx pardinensis), belonged to the same genus as our modern day Cheetah (Acinonyx jubatus), and probably looked very similar, but it was much bigger.
At around 120-150 kgs (265-331lbs), it was as large as an African lioness, and was able to take on larger prey than its delicate modern day counterpart.
The Giant Cheetah was also adapted to fast running, but there’s some debate on whether it could run as fast as the modern Cheetah, due to its larger weight, which, according to some, probably made it somewhat slower.
Others, however, have suggested that the Giant Cheetah, having longer legs and bigger heart and lungs, was probably able to run as fast, or even faster, than the cheetah does today – that’s over 115 kph (72mph)! The Giant Cheetah lived in Europe and Asia (from Germany and France to India and China) during the Pliocene and Pleistocene epochs; it went extinct during the last Ice Age. Due to its living in colder environments than modern day Cheetahs, it is possible that the Giant Cheetah had longer fur and perhaps a lighter coloration.
Xenosmilus is a relative to Smilodon (the ever famous “sabertoothed tiger”), but instead of having long, blade-like fangs, it had shorter and thicker teeth. All of its teeth (not only the canines) had serrated edges to cut through flesh, and were more like the teeth of a shark or a carnivorous dinosaur, than the teeth of modern day cats.
Xenosmilus didn’t strangle its prey as modern day cats do; it only had to bite off a huge chunk of flesh from its victim, and wait until it bled to death. A Xenosmilus’ kill was much bloodier and messier than that of any big cat today!
Xenosmilus was a very big cat for today’s standards; at 180-230 kgs (397-507lbs), it was as big as most adult male lions and tigers, and was much more robust, with shorter, stronger limbs and a very powerful neck. The remains of this cat have been found in Florida, along with those of giant prehistoric peccaries (pig-like animals) which were seemingly its favorite meal. It lived during the Pleistocene period but no one knows exactly when it went extinct; whether it encountered (or ate) humans or not is anyone’s guess.
Jaguars today are rather smallish cats if compared to lions or tigers; they usually average 60-100 kgs (132-220lbs), and the largest males (recorded from South America) were around 150 kgs (330lbs), about the size of an African lioness. In prehistoric times, however, both North and South America were home to gigantic jaguars, belonging to the same species as modern day jags (Panthera onca) but much bigger.
These giant jaguars also had longer limbs and tails than jaguars living today; scientists believe that jaguars used to be open plain denizens, but that competition with American lions and other big cats forced them to adapt to more forested environments, where they developed their modern short-legged appearance.
Giant prehistoric jaguars were about the size of a fully grown lion or tiger, and were probably several times stronger, with a much stronger bite.
There are two subspecies of prehistoric giant jaguars known to date; Panthera onca augusta, from North America, and Panthera onca messembrina, from South America (also known as the Patagonian panther). Both of them were active during the Pleistocene period, but went extinct about 11.000 years ago, during the last Ice Age.
Unlike the Giant Jaguar mentioned before, the European jaguar or Panthera gombaszoegensis did not belong to the same species as modern day jags. Nobody knows what the European Jaguar looked like; some scientists have suggested that it probably looked much like a modern day jaguar (hence the name), or perhaps, a cross between a lion and a jaguar. A fossil feline from Eastern Africa has been said to resemble the European jaguar, and described as having “tiger-like” features as well.
Regardless of its external appearance, it is obvious that 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.
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).
It was one of the most dangerous and powerful predators during the last Ice Age in Europe, and there is evidence that it was feared, and perhaps worshiped, by prehistoric humans. Plenty of cave paintings and a few statuettes have been found depicting the Cave Lion. Interestingly, these show the animal as having no mane; barely a ruff around the neck sometimes, as in modern day tigers.
Confusingly, some cave paintings also show the Cave Lion as having faint stripes on its legs and tail. This has led some scientists to suggest that perhaps the Cave Lion was actually more related to the Tiger. Genetic studies on the ancient bones, however, have confirmed the original idea that the Cave Lion is, indeed, a lion after all – albeit, if cave artists are to be trusted, a very unusual looking one.
Also known as the “Scimitar cat”, Homotherium was one of the most successful felines in prehistoric times, being found in North and South America, Europe, Asia and Africa. It adapted well to a variety of habitats, including the sub-arctic tundra and survived for five million years until its extinction 10,000 years ago.
Homotherium was seemingly a pack hunter, adapted to fast running and active mostly during day (thus avoiding competition with other, nocturnal predators). It had very long forelegs and shorter hind legs, which gave it a slightly hyena-like appearance. Although Homotherium is not very famous for its size, some fossil remains of a Scimitar cat unearthed recently in the North Sea suggest that they could reach 400 kgs (882lbs) in weight, being larger than modern day Siberian tigers.
If you are wondering what these enormous, pack-hunting cats ate, some paleontologists believe that they were quite skilled mammoth hunters, although their ability to run at high speed would allow them to chase after fleet-footed animals as well.
Despite Smilodon’s fame as the classic “sabertooth tiger”, its short tail and different body proportions were very different from an actual tiger.
Machairodus, on the other hand, probably looked pretty much like a gigantic tiger with saberteeth; 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.
Machairodus is seldom mentioned as a giant feline, but some fossil remains found in Chad, Africa, (and classified as a new species, Machairodus kabir), suggest that this creature was among the largest cats of all times- weighing up to 490 (1080lbs) or perhaps 500 kgs (1102lbs), and being “the size of a horse”. It fed on elephants, rhinos and other large herbivores which were abundant at the time.
Machairodus kabir probably looked somewhat like the gigantic “sabertooth tiger” in the film 10.000 B.C, although sadly, it went extinct during the Miocene period, long before the appearance of humans.
Often called the largest cat of all times, 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. Most scientists believe that the American Lion was a gigantic relative to modern lions, perhaps even belonging to the same species (in which case the correct name would be Panthera leo atrox).
However, others are not so sure, and suggest that the American lion, although closely related to the lion, was a separate species and probably looked quite different on the outside. Recently, it was suggested that the American lion was probably more similar to the jaguar.
One thing is certain; the American lion was the largest cat in North America during the Ice Age, weighing up to 470 (1036lbs), perhaps even 500 kgs (1102lbs), and being able to take on very large prey. There is still some debate about its hunting technique, for although modern day lions hunt in groups, American lion remains are scarce, suggesting that these cats were probably solitary hunters.
This would make sense if we consider that the North American Smilodon fatalis, a species of sabertooth, was seemingly a pack hunter. By hunting alone and preying on different animals, it may be that the American lion avoided competition with the sabertooth, explaining why both cats coexisted successfully for such a long time.
This is easily the most obscure cat in the list, being known from fragmentary remains which have yet to be formally described. I should mention that the “Pleistocene tiger” is not a separate species, but rather the “early version” of the same tigers we see today. Tigers evolved somewhere in Asia about 2 million years ago, specifically to prey on the enormous diversity of large herbivores living on the continent at the time. Tigers are the largest felines nowadays, with large Bengal and Siberian males reaching up to 300 kgs (661lbs) or more.
However, during the Pleistocene, the food supply was greater, and so the tigers themselves were bigger. Some fragmentary remains (including massive jaws and fangs) have been found in Russia, China and Java, suggesting that these “Cave tigers” could reach up to 490 kgs (1080lbs) in weight, being worthy contenders for the title of largest cat ever.
The ever popular “sabertooth tiger”, 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.
However, the South American species Smilodon populator dwarfed both of them, weighing 300 kgs (661lbs) on average and reaching up to 500 kgs (1102lbs) when fully grown!
Smilodon was not as agile as modern day big cats, but it was immensely powerful, with thicker, stronger limbs and neck than modern day cats, and particularly long claws to hold on to prey. Its fangs could reach 30 cms (12″) in length, and were perfect for causing mortal injury to mammoths, ground sloths and possibly any large animal unlucky enough to be ambushed by this super predator.
Smilodon went extinct 10,000 years ago, meaning it encountered humans, and probably hunted them once in a while. But perhaps the most amazing thing about Smilodon, is that it is the only prehistoric cat known to have caused the extinction of an entire species. The victim was another formidable predator, the saber-toothed marsupial or marsupial relative known as Thylacosmilus.
This beast ruled South America for millions of years, until the sea levels became lower and North America became connected to South America.
Smilodon, native to North America, made the journey to South America about 2 million years ago. Thylacosmilus disappeared practically at the same time, outcompeted, and perhaps even, hunted to extinction by the cat. In other words, Smilodon basically conquered an entire continent, driving its less adaptable competitors to extinction, therefore its place as #1 in this list.
