The sabertooth tiger may have become extinct due to climate change, lack of large prey and competition from humans. However, there’s no fossil evidence of tooth wear to suggest sabertooth cats starved. Although climate change killed off the dinosaurs, sabertooth cats consumed mammals almost exclusively.Know More
Palaeontologists have long assumed that sabertooth tigers, native to North America, died out because they no longer had enough food. However, a 2012 study of wear patterns on fossil teeth found no evidence to suggest starvation. When prey populations decline, predators typically eat more of each carcass. Chewing large, heavy bones creates distinct wear patterns on teeth and higher rates of breakage. No fossil examples suggest that sabertooths didn’t have enough to eat.
Another possible explanation for sabertooths’ extinction is that North America’s climate cooled rapidly. Although dinosaurs became extinct because of this cataclysmic climate change, it didn’t affect sabertooths’ typical prey items – mammoths, camels, giant ground sloths, bison and horses – to the same degree. Habitat loss due to climate change forced these prey animals to evolve to smaller species, but they were still plentiful. However, when the first humans arrived in North America about 12,000 years ago, climate change as well as increased competition for food may have led to the extinction of many species of native megafauna.Learn more about Large Cats
Tigers are at risk of extinction due to poaching for illegal wildlife markets, habitat loss and fragmentation, conflict with humans in close proximity and rising sea levels due to climate change. As of 2014, there are only 3,000 to 3,500 tigers of any species left in the wild. The South China tiger is one of the world's most endangered animals, and three species of tiger are already extinct.Full Answer >
Javan tigers became extinct mainly because their natural habitats were destroyed and cultivated for the benefit of a rapidly growing human population, according to About.com. They were hunted down and poisoned, and were considered to be pests because of how common they were in Java in the early 19th century. There was also increased competition for prey when wild dogs were introduced to Java.Full Answer >
The saber-tooth tiger was essentially hunted so heavily by primitive human populations that it became extinct. The last saber-tooth tiger is thought to have become extinct around 10,000 years ago.Full Answer >
Black panthers are considered a dominant predator at the top of the food chain in their environments, and they prey upon deer, tapir and wild boar, but will also eat anything they can dominate when large prey is scarce. Panthers are generally considered an apex predator with no natural predators in the wild.Full Answer >
