The woolly rhinoceros lived throughout northern Europe and Asia during the Pleistocene epoch until it became extinct relatively recently following the last glacial period. They grew up to 6 1/2 feet tall, 12 feet long, and weighed up to 7,000 lb and were adapted well to the harsh temperatures during the glacial periods. Images of woolly rhinoceroses adorn a number of prehistoric cave dwelling walls.

Dinoceras mirabile, now known as Dinoceras anceps were mammals that lived during the early Eocene 52 million years ago in the areas of Utah and Wyoming. They were herbivores that grew to 7 1/2 ft tall, 13 ft long, and weighed 2 1/4 tons. An exceptionally thick skull left a small cranial cavity for brains.

Titanotheres and Tortoises. Titanotheres, or Brontotheres were hoofed mammals that lived between 56 and 34 million years ago during which some species evolved to have huge bulky body sizes up to 8 feet in height with with strong, pillar-like limbs, massive skulls, and bizarre hornlike skull appendages. Their remains are numerous providing clear records of varying forms.

Aepycamelus were camelids that lived in the prairies where the great plains of North America are now during the Miocene between 20 and 5 million years ago. They had leathery skin pads on their legs that functioned as cushions when the animals knelt to rest like those of modern camels.

Hyaenodon (left) were a genus of carnivorous mammals that lived from 42 to 16 million years ago. They varied in size and form. Some species were amongst the largest terrestrial carnivorous mammals of the time. One species, Hyaenodon gigas, grew to more than 10 feet long and weighed more than 1,000 lbs. Moropus (right) lived in North America during the Miocene from about 23 to 14 million years ago. Moropus were herbivores with long front legs and horse-like snouts. They are related to horses, rhinos, and tapirs, although they differed in that they had three-clawed front feet rather than hooves, which they may have used for foraging or defending themselves.

Arsinoitherium are related to elephant species. These extinct mammals were rhinoceros-like herbivores that lived during the late Eocene and the early Oligocene of northern Africa from 36 to 30 million years ago in areas of tropical rainforests and mangrove swamps. They stood 5 feet tall at the shoulders, were 10 feet long and weighed more than 2 1/2 tons. Their enormous horns were solid bone.

Horned Gophers lived in the prairie areas of Nebraska and have been extinct since the Pliocene. They had two horns which were made of compressed hair and nail like substances. Horned gophers are the smallest known mammals to ever have horns and the only known horned rodents.

Phenacodus lived about 55 million years ago, evolving only 10 million years after the dinosaurs had gone extinct and was one of the earliest of the first hoofed mammals, possibly a predecessor of the long leaniage of hoofed animals.

Hypohippos a Miocene Horse, Charles R. Knight.Hypohippos was a Miocene Horse that inhabited heavy undergrowth in North America. Early North American Horses were not the ancestors of present day horses.

Hyracotherium, the earliest known horse, lived in the early Eocene, about 50 million years ago in Asia, Europe and North America, was less than 20 inches long and stood less than 10 inches tall at the shoulder. This tiny horse was preyed on by early dog and cat like predators and even giant carnivorous birds!

This is another illustrated version of the Great Toothed Diver, Hesperornis regalis, an extinct five foot long diving bird that lived during the Cretaceous period - with teeth! Hesperornis regalis did not have wings, but propelled itself with powrful hind legs and lobed toes similar to the grebes of today. Hesperornis regalis lived in the prehistoric North Sea, the West Siberian Sea, and the Great American Inland Sea, preyed upon fish, crustaceans, cephalopods and mollusks and were preyed upon by Mosasaurs.

Diatrymas were another large bird which you would not have been able to outrun, however, it is uncertain whether they were herbivores or carnivores. With that beak you would run regardless. It may have been used to crack nuts or to rip flesh. They grew to 6 feet tall and weighed more than 200 lbs. They lived about 60 million years ago in North America and Europe

Elephant birds lived on Madagascar until their extinction in the 17th century. Sightings in Madagascar were recorded as late at the 1640s and 1650s. Aepyornis was the largest bird in the world at that time standing 10 feet tall and weighing almost 900 lbs. Remains of eggs have been found that measure more than a foot long and 3 feet in circumference. Marco Polo may have encountered Elephant Birds in the 12th Century. Descriptions recorded in his travels are believed to describe elephant birds.
