Daeodon

Daeodon

Daeodon was one of the largest entelodonts, living in North America during the late Oligocene and early Miocene. It had a huge skull, powerful jaws, and a muscular build, making it a dominant omnivore and likely a top scavenger.

 

Doedicurus

Doedicurus

Doedicurus was a heavily armored mammal related to armadillos, living in South America during the Ice Age. It had a large, domed shell and a spiked tail used for defense against predators.

 

Entelodonts

Entelodont

Entelodonts were massive, pig-like omnivores that lived during the late Eocene to Miocene. They had a huge head, strong jaws, and a bulky body, making them a formidable scavenger and predator.

 

Embolotherium

Embolotherium

Embolotherium was a rhino-like herbivore from the Eocene of Central Asia. It had a large, bony crest on its head, possibly used for display or sound resonance, and browsed on soft vegetation.

 

Hyaenodon

Hyaenodon

Hyaenodon was a large carnivorous mammal that lived from the Eocene to Miocene epochs. It had a long skull with powerful jaws and was a dominant predator in its environment, capable of crushing bone with ease.

 

Indricothere

Indricothere

Indricothere was the largest land mammal ever to exist, living during the Oligocene. It was a hornless relative of the rhinoceros, with a long neck and massive body, feeding on treetop vegetation.

 

Macrauchenia

Macrauchenia

Macrauchenia was a long-necked, hoofed mammal from South America, resembling a camel with a short trunk. It lived from the Miocene to the Ice Age and grazed in open grasslands.

 

Wolly Mammoth

Woolly Mammoth

Woolly Mammoths were a giant, shaggy elephants that lived during the Pleistocene. they had long, curved tusks and a thick coat of fur, helping them survive in icy environments across Eurasia and North America.

 

Megatherium

Megatherium

Megatherium was a giant ground sloth from South America that lived during the Pleistocene. It had massive claws and a bulky frame, feeding on leaves and possibly standing upright to reach higher branches.

 

Paraceratherium

Paraceratherium

Paraceratherium was the largest land mammal ever to exist, living during the Oligocene. It was a hornless relative of the rhinoceros, with a long neck and massive body, feeding on treetop vegetation.

 

Smilodon

Smilodon

Smilodon was a powerful saber-toothed cat that lived in the Americas during the Ice Age. It had massive forelimbs and long, curved canine teeth, which it used to take down large prey.

 

Woolly Rhinoceros

Woolly Rhinoceros

Woolly Rhinoceros was a large Ice Age mammal adapted to cold climates. It had a thick coat of fur and a prominent curved horn, which it used to clear snow and graze on frozen grasslands.

 

Gomphothere

Gomphothere

Gomphothere was a large, elephant-like mammal that roamed the Americas during the Ice Age. It had a long trunk and distinctive tusks, which it used to dig for roots and strip bark from trees. Unlike modern elephants, some species had four tusks and a flatter skull, helping them adapt to diverse environments.

 

Mastodon

Mastodon

Mastodon was a shaggy, elephant-like mammal that lived across North America during the Ice Age. It had straight tusks and a low, sloping skull, which helped it browse on shrubs and trees. Unlike mammoths, mastodons had cusped teeth suited for chewing tough vegetation in forested environments.

 

Megaloceros

Megaloceros

Megaloceros was a giant deer that lived across Europe and Asia during the Ice Age. It had enormous, wide-spreading antlers and a strong, muscular build, which it used for display and defense. Often called the "Irish Elk," it grazed in open woodlands and meadows, feeding on grasses and shrubs.
