If you search for the fastest land animals on the Internet, you will find many “fastest animals” lists, most of them are popular “top list” sites. But, in fact, there is a tendency to overestimate the speed of fast animals. Even the speed of the world’s fastest land animal, cheetah’s speed is usually highly overestimated.

After the extinction of the dinosaurs, approximately 66 million years ago, the rise of mammals begun. There were mammals on earth before that date, but after the Cretaceous–Paleogene (K–Pg) extinction event (a mass extinction of some three-quarters of the plant and animal species on Earth—including all non-avian dinosaurs), mammals took over the medium- to large-sized ecological niches.
Some of them reached enormous sizes, usually they were larger than today’s counterparts (with the exception of whales). Here are some of the largest known prehistoric mammals.

Bite force is an important property of carnivore ecology, because these amazing animals need to kill their prey as easily as possible, and the bite force is an vital factor in this context. Here are the top 22 most powerful bites in carnivore land mammals.

Like all prehistoric counterparts of today’s animals, the prehistoric cats were usually larger, heavier and more robust than today’s felines. Here are the top five largest prehistoric cats.

Four of the five species of the big cats (the Panthera genus – lion, tiger, leopard, jaguar and snow leopard), the exception being the snow leopard can hybridize with each other to produce numerous hybrids. In fact, breeding of two different pantheras has been banned in many zoos and animal sanctuaries due to no conservation value of the hybrid, and the risk it poses on the mother that gives birth to it. For instance, the liger’s increased growth rate and enormous size can cause the tigress giving birth to have a difficult delivery, endangering both the mother and her liger cubs, which may be born prematurely or require a Caesarian. Common problems in cubs that survive are neurological disorders, obesity, genetic defects, and a shortened lifespan; though a few have reportedly made it to their twenties, many don’t survive past the age of seven. Moreover, male ligers have lowered testosterone levels and sperm counts, rendering them infertile while females, though capable of reproducing with either a lion or a tiger, often give birth to sickly cubs that don’t survive.
However, hybrids do occur by accident in captivity.

Ligers are the largest cats on Earth. They are more than 900 pounds (~408 kg) and 12 feet (~3.65 m) long, weighing almost 100 times more than house cats and almost twice as much as either Panthera tigris (tiger) or Panthera leo (lion).
