Edaphosaurus amidst cordaites - An Edaphosaur among cordaites (Cordaites angulostriatus) 300 million years ago in Europe. Edaphosaurus was a large herbivore (more than 3m long) living in Permian. A ten-foot-long, 600 pound synapsid of the genus Edaphosaurus boreages in a brackish mangrove-like swamp of gymnosperms of the genus Cordaites 300 million years ago in what is today Western Europe. Like its better-known synapsid cousin Dimetrodon, Edaphosaurus had a large sail on its back supported by elongated neural spines, however unlike Dimetrodon, these spines include numerous short cross bars; while the sail may have served the purpose of both helping to regulate body temperature and as sexual display, the purpose of the cross bars is unknown. Jaw and teeth structure suggests that Edaphosaurus probably dined on both plants and small invertebrates, such as mollusks. Tree-like Cordaites, now extinct, grew on wet ground similar to the Everglades in Florida, numerous fossils of which are now found associated with coal deposits. Also in this image are several examples of extinct seed fern of the genus Neuropteris as well as smaller examples of generic fern that may have been present during the period. Other fauna include two examples of the large dragonfly-like Meganeura, a centipede, and in the foreground a juvenile prehistoric shark of the genus Xenacanthus, its distinctive spine projecting from the back of its head and out of the water

Deinotherium - Deinotherium appeared in the middle Miocene and the genus fades in the lower Pleistocene. It probably looked like modern elephants, except that its trunk was shorter, its defenses were attached to the lower jaw (not to the skull), and they pointed downwards. Deinotherium is the third largest known terrestrial mammal ever; only Baluchitherium grangeri and Mammuthus sungari were larger. Males were generally 3.5 to 4.5 m tall to the shoulders, although some large specimens were able to measure up to 5m. Their weight was estimated to be between 5 and 10 tonnes and above 14 tonnes for the larger males. Deinotherium crosses the rolling plains of what is today Europe. A prehistoric relative of modern elephants, Deinotherium was larger and had a shorter trunk and downward-curving tusks attached to its lower jaw. Deinotherium is the third largest land mammal known to have existed; only Paraceratherium and some mammoths were larger. Deinotherium likely behaved like modern elephants and may have lived side-by-side with the early human ancestor Australopithecus

Doliosauriscus - Doliosauriscus was a fossil carnivorous reptile of the order of Therapsides and the suborder of Dinocephales. He lived in the middle of Permian about 265 million years ago. In the picture, in the background, a dimetrodon. 12-foot-long dinocephalian therapsids of the genus Doliosauriscus face off in a dry mid-permian landscape 265 million years ago in what is today Russia. On the horizon is a synapsid of the genus Dimetrodon. Vegetation includes various ferns and cycads. Similar to its better-known relative Titanophoneus, Doliosauriscus was a carnivore, one of the largest predators of its time with large dagger-like canines in front and sharp incisors and flat molars in back for grinding up flesh

Woolly rhinoceros - Woolly rhinoceros - Woolly rhinoceros (Coelodonta antiquitatis), also known as cloisonnee nostrils, was a species of large rhinoceros (1.6 to 2 metres high at withers and up to 3.5 metres long, weighing 2 to 3 tonnes) characterized by A thick woolly fleece. He lived in the cold steppes which covered in Pleistocene much of Eurasia. At its peak, less than 30,000 years ago, it was found from central Spain and southern England to Mongolia and southern Siberia. A woolly rhinoceros (Coelodonta antiquitatis) wanders the snow-covered terrain of Northern Europe 200 thousand years ago. In the foreground is a common rabbit of the family Leporidae. About the size, and maybe a little larger, than today's white rhinoceros, the woolly rhinoceros is believed to be related to the modern Sumatran rhinoceros. Covered with thick fur (AKA pelage), this stocky herbivore was well-suited to the cold climates associated with the Pleistocene glaciations. Woolly rhinoceros remains have been found dating as far back as 3.6 million years and as recent as 8,000 years ago. Cave paintings featuring the woolly rhinoceros have been identified; human and Neanderthal hunting, along with climate change, may have contributed to its extinction

Lycaenops - Lycaenops is a genus of Gorgonopsian, that is, a therapside (mammalian reptile) that lived 270 million years ago, during the second part of Permian. Its name comes from the Greek and means “wolf face”. It was about 1 metre long. A three-foot-long, 35 pound carnivorous therapsid (mammal-like reptile) of the genus Lycaenops wanders a mountainous Mid-Permian landscape 270 million years ago in what is today South Africa. Vegetation includes various ferns forming ground cover and a large cycad. While reptilian in origin, Lycaenops more resembled a modern wolf with a long and slender skull, wolf-like fangs, and long legs held close to its body which probably enabled it to out-run the small reptiles and dicynodonts it dined on

Kannemeyeria grazing - An artist's view of Kannemeyeria 240 million years ago, in South Africa. These missing animals 3 metres long were not dinosaurs but dicynodonts, herbivorous mammalian reptiles (Therapsides) living in Permian. Large dicynodonts of the genus Kannemeyeria graze on ferns 240 million years ago in what is today South Africa. The trees on the right are Glossopteridales while those on the left are Ginkgos. About the size of a modern ox with tusks and a beak for grazing on tough vegetation, Kannemeyeria was one of the first large herbivores of the Triassic era. They won't dinosaurs, rather they are classified as mammal-like reptiles

Large dicynodonts of the genus Kannemeyeria graze on ferns 240 million years ago in what is today South Africa. The trees on the right are Glossopteridales while those on the left are Ginkgos. About the size of a modern ox with tusks and a beak for grazing on tough vegetation, Kannemeyeria was one of the first large herbivores of the Triassic era. They won't dinosaurs, rather they are classified as mammal-like reptiles

Doedicurus and Eremotherium - Doedicurus clavicaudatus is a glyptodon, a giant tattoo, that lived during pleistocene until 11,000 years ago. It was three metres long and weighed two tons. Behind it is an eremotherium. Prehistoric glyptodonts of the genus Doedicurus graze on grassy plains 25,000 years ago in what is today South America. In the background is a giant ground sloth of the genus Eremotherium. With a turtle-like shell five feet tall and weighing over two tons, Doedicurus was the largest known glyptodontid, an extinct family of heavy-armored herbivores related to modern armadillos. Doedicurus carried a large spiked tail that could have helped protect it from large predators and other Doedicurus. Eremotherium was a Megatheriid that grew to 20 feet long and weighed up to three tons

Jonkeria - Artist view of Jonkeria dinocephals 262 million years ago, in South Africa. These missing animals were not dinosaurs but mammalian reptiles (Therapsides) living in Permian. 12-foot-long 500 pound dinocephalian therapsids of the genus Jonkeria pause in a shallow stream in a dry mid-Permian landscape 262 million years ago in what is today South Africa. Vegetation includes various ferns. Jonkeria was large mammal-like reptile with a stout piglike build. Paleontologists haven't been able to determine whether Jonkeria was an herbivore, carnivore, or possibly like modern pigs an omnivore

Cotylorhynchus - Cotylorhynchus was a large mammalian reptile (Synapside, Pelycosaur) living herbivorous from early Permian to mid-Permian (299 to 265 million years). They were the largest terrestrial animals of their time, measuring 6 metres long and weighing two tons. Giant, 20-foot-long and one-ton synapsids of the genus Cotylorhynchus forage in an Early Permian swamp 275 million years ago in what is today North America. Also in this image on the lower left is a 3-foot long lepospondyl amphibian of the genus Diplocaulus. Vegetation includes ferns and horsetails in the foreground and on the horizon is a forest of ginkgos. Cotylorhynchus is the largest known non-mammalian synapsid and was the largest land animal of its time. An herbivore, Cotylorhynchus had a massive barrel-shaped body and limbs with a relatively small head, making it perhaps one of the most unattractive land animals to have ever walked the Earth. Standing about 6 feet tall at the shoulder Cotylorhynchus probably had no predators; even the fierce Dimetrodon (also a synapsid) weighed little more than 300 pounds compared to Cotylorhynchus' 2,000

Tyrannosaurus rex and Purgatorius - A seven-ton Tyrannosaurus in a cretacious forest 68 million years ago. A Purgatorius is watching his way. Purgatorius is the name of a genus of four fossil species considered to be the oldest representatives of primates (proto-primates). A 40 foot long, seven ton coelurosaurian theropod dinosaur of the species Tyrannosaurus rex wanders among oak trees and ground ferns 68 million years ago on a Cretaceous island continent known as Laramidia in what is today the western United States.This example of Tyrannosaurus rex hosts fur-like downy feathers on its head, back and along the top of its tail. While it's not known whether Tyrannosaurus rex was feathered, other tyrannosaur fossils have shown tantalizing evidence of them.On the lower left is a rodent-size proto-primate of the genus Purgatorius, and in the lower middle is an amphibious tetrapod of the family Salamandridae
