Dimetrodon among Alethopteris - Dimetrodon among Alethopteris - Artist's view of a dimetrodon among seed ferns (Alethopteris). Dimetrodon is a mammalian reptile (Therapside), carnivore living in Permian. Dimetrodon was the apex predator of its time and likely had few enemies save for other Dimetrodon. They came as large as 11 feet long, 4 feet tall, and weighing as much as 300 pounds. Their reptilian hide, a relative novelty for that period, ensured their survival out of water. The large sail may have helped them to regulate body temperature, a survival advantage during the extremes of hot and cold during the Early Permian. Given that Dimetrodon is more closely related to mammals than dinosaurs, it could be that our own body's ability to regulate temperature had its origin in this ancient beast. Alethopteris was a seed fern that populated much of the world during the Carboniferous and Early Permian periods. Long extinct, fossilized leaves from the Alethopteris are commonly found today

Dimetrodon Grandis - Dimetrodon grandis portrait - Artist's view of a dimetrodon about 280 million years ago. Dimetrodon is a carnivorous mammalian reptile (Therapside) living in Permian. An eleven foot long Dimetrodon grandis traverses an Earth that became cooler and dryer during the Early Permian period. 280 million years ago - long before the reign of dinosaurs - Dimetrodon emerged as the dominant land predator, a position they held for the next 20 million years. Contrary to their reptilian stance and dinosaurlike appearance, Dimetrodon are in fact more closely related to mammals, and hence to humans, than to dinosaurs or reptiles

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

Estemmenosuchus - Estemmenosuchus mirabilis waterside - Artist's view of three Estemmenosuchus mirabilis by a lake, 225 million years ago. These disappeared animals were not dinosaurs but herbivorous mammalian reptiles (Therapsides) living in Permian. Resembling modern day hippopotami, three Estemmenosuchus mirabilis face off in a Paleozoic lake 255 million years ago in what is today the Perm region of Russia near the Ural Mountains. About the size of a modern adult bull, Estemmenosuchus mirabilis was a plant-eating early ancestor of today's mammals

Moschops - Artist's view of two Moschops 250 million years ago in South Africa. These disappeared animals were not dinosaurs but herbivorous mammalian reptiles (Therapsides) living in Permian. Two giant Moschops face off on a sandstone mesa 250 million years ago in what is today the Karoo region of South Africa. Moschops was not a dinosaur, rather it was a mammal-like reptile that, like Dimetrodon, was more closely related to mammals than to true reptiles such as lizards. Moschops was a heavy-built, 4-legged herbivore that grew up to 16 feet long

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

These disappeared animals were not dinosaurs but herbivorous mammalian reptiles (Therapsides) living in Permian. An Estemmenosuchus mirabilis stands before a lake 255 million years ago in what is today the Perm region of Russia near the Ural Mountains. An ungainly plant-eater, it was the largest animal of its day and is known for its distinctive horns. Maybe not the most handsome of beasts, Estemmenosuchus mirabilis was an early ancestor of today's mammals. In this image it stands among several varieties of fern while cycads known as Bjuvia simplex populate the far side of the lake

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
