![]() ![]() A carnivorous reptile, Megalania is related to modern-day goannas. It lived in Australia in the Pleistocene epoch. It had long tusks and a trunk, and lived in the forests of North America. The Mastodon was an ancestor of the elephant that walked the Earth in the Pleistocene epoch, around 10,000 to 11,000 years ago. With a long skull, and powerful, doglike body, it would have had little to fear from most other animals. The largest Hyaenodons were among the largest predators of their time. Hyaenodon is a genus of large carnivorous mammals that lived from the Eocene to the mid Miocene epochs. With a shell that was around 1.5 m (5 ft.) in length, and a total body length of around 3.3 m (11 ft.), it would have been an impressive sight walking through the South American forests and grasslands in which it lived. Glyptodon was a giant armadillo of the Pliocene and Pleistocene epochs. It lived in North America, Europe and Asia from the mid-Paleocene to the early Neogene period. ![]() Originally thought to be a type of prehistoric pig, it is now believed to be more closely related to whales and hippos. EntelodonĮntelodon was a hoofed animal that lived in the Paleogene period. Coelodonta lived during the last ice age. It was found in Europe, Africa and Asia, and several species have been identified. This huge animal was covered with thick fur and had two large horns on its nose. CoelodontaĬoelodonta is also known as the woolly rhinoceros. It is the largest beaver ever to have lived, but it had a small brain in proportion to its body size and may not have been as smart as its modern day counterpart. Brygmophyseter grew to around 7 m (23 ft.) long, CastoroidesĬastoroides was a 2.5 m (8 ft.) long giant beaver that lived in North America during the Pleistocene epoch. Its name means ‘biting sperm whale’, and for good reason its teeth were up to 14 cm (5.5 in.) long, and it was an apex predator. Analysis of its skull suggests that it may have had the strongest bite force of any animal! Brygmophyseterīrygmophyseter was an early sperm whale that lived in the Miocene epoch. Its jaws were full of long, dagger-like teeth. In fact, Basilosaurus was an early whale that lived in the Eocene epoch of the Paleogene period.īasilosaurus was around 21 m (70 ft.) long and had a 1.5 m (5 ft.) skull. BasilosaurusĪlthough its name, which includes the word ‘saurus’, suggests that Basilosaurus was a reptile, it was later found to be a mammal. Andrewsarchus was discovered in Mongolia by naturalist Roy Chapman Andrews, after whom the genus was subsequently named.Īndrewsarchus was a large-snouted predator, and, based on skull measurements, may have been the largest ever carnivorous mammal (that lived on land). It was an early artiodactyl (hoofed animal), related to hippos and whales. List of Prehistoric Animals That Are Not Dinosaurs AndrewsarchusĪndrewsarchus was a large mammal that lived in the Paleogene period. We would like to extend our thanks to Rupert Harwood for his invaluable help in compiling this article. We’re going to meet giant horses, killer birds, the biggest snake that ever lived, plus old favorites such as saber-toothed cats and woolly mammoths. We’ve already made a list of awesome prehistoric animals that lived with dinosaurs, so this page contains pictures and information on prehistoric animals that lived after the dinosaurs. Not every amazing prehistoric creature was a dinosaur! This list contains some of the world’s most awesome – and strangest – prehistoric animals, many of which were early relatives of familiar modern-day animals.Īre you brave enough to meet the Titanoboa? Some, such as the glaciers in the summit craters of Mount Redoubt and Katmai Volcanoes, have reformed following eruptions during the 20 th century.A list of prehistoric animals that are not dinosaurs. Others may date from other post-Pleistocene colder climate events. Many formed as recently as the start of the Little Ice Age, approximately 700 years ago. For Greenland, ice cores and related data suggest that all of southern Greenland and most of northern Greenland were ice-free during the last interglacial period, approximately 125,000 years ago. Then, climate was as much as 3-5 o Fahrenheit warmer than the interglacial period we currently live in.Īlthough the higher mountains of Alaska have hosted glaciers for as much as the past 4 million years, temperate glaciers in Alaska are generally much, much younger. ![]() Other areas, such as valley glaciers of the Antarctic Peninsula and glaciers of the Transantarctic Mountains may date from the early Pleistocene. Parts of the Antarctic Continent have had continuous glacier cover for perhaps as long as 20 million years. It depends on which glaciers you are considering. ![]()
