Earth at the end of Permian - Ring arcs over the Permian Earth - A ring of rocks and dust is orbiting the Earth. The massive continent below is Pangee and the ocean to the west is Panthalassa. This is what Earth was supposed to look like at the end of Permian, about 260 million years ago, before the first dinosaurs appeared. This ring around the Earth was of earthly origin, constitutes debris thrown into orbit by collision with a meteorite or comet. Over time, these debris have either fallen or fallen back to Earth in a meteorite rain. A dusty ring arc orbits four thousand miles above Earth's equator. The massive continent below is Pangea and the ocean to the west is Panthalassa. This is how the Earth may have appeared during the end of the Permian period, a time just prior to the appearance of the dinosaurs, when continental drift was pulling Pangea apart into the seven continents we know today. 260 million years ago the Earth may have been host to ring arcs similar to the incomplete rings that currently circumscribe the planet Neptune. Unlike Neptune's rings, the ring arcs around the Earth were of terrestrial origin, debris thrown into orbit by a collision with a large meteorite or comet. The debris consisted of tiny pebbles that were once molten droplets of ejecta, long since cooled in the vacuum of space. The orbit of the ring arc would eventually decay, returning the debris back to Earth as a shower of meteorites. This debris is found on Earth's surface today in the form of dark, glassy objects known as tektites — Earth at the end of Permian - Ring arcs over the Permian Earth - A ring of rocks and dust is orbiting the Earth.

Coelacanthe - Coelacanth portrait - A coelacanth swim in the ancient Tethys Ocean, 390 million years ago. A prehistoric, 130 pound Coelacanth swims the Paleo Tethys Sea 390 million years ago during the Middle Devonian period. Related to lungfishes and tetrapods, Coelacanths were thought to have gone extinct 65 million years ago until a living specimen was found off the east coast of South Africa in 1938

Arthropleura - An arthropleura crawls among ferns in a carboniferous forest 310 million years ago. The Arthropleura is considered to be the largest arthropod of all times measuring 2-3 metres in length. He is a distant relative of arthropods such as a thousand-legged. A four foot long Arthropleura crawls amidst seed ferns from the genus Neuropteris in a Carboniferous forest 310 million years ago in what is today Scotland. Growing up to 8 feet long and 18 inches wide, Arthropleura was the largest known terrestrial arthropod of all time. A combination of a higher percentage of atmospheric oxygen and relatively few terrestrial predators may have enabled Arthropleura to evolve to such an enormous size. Despite its fierce appearance, Arthropleura is currently believed to have been a vegetarian. In the shadows on the upper right are “” roachoids,””” primitive ancestors of modern cockroaches

The First Trees on Earth - Artist View - First Trees - Artist view - 385 million years ago, in the upper Devonian, the first trees began to appear on Earth. In this illustration, the archaeopteris, considered the first tree, is present at different stages of its evolution, with on the left a young specimen of 6 metres, in the centre a tree twice as large, on the right, an even older specimen. At the extreme right, a strain of an old Archaeopteris collapse. 385 million years ago, near the end of the Devonian period, the first trees began to populate the Earth. Considered the first modern trees, the Archaeopteris were a part of the Earth's primitive forests for the next 25 million years. Unlike the trees we know today, Archaeopteris was in fact a primitive fern that reproduced by means of spores instead of seeds. While terrestrial plants had been around for 130 million years prior to Archaeopteris, this was the first plant to solve the biomechanical challenges of supporting and nurturing ever larger sizes, enabling these Archaeopteris to grow to heights of 70 feet and more, over twice the height of the Calamites. In this image, four stages of the life of the Archaeopteris are illustrated. On the far left nearest our vantage point is a young, 20 - foot Archaeopteris, and in the center at twice that height is a medium - aged Archaeopteris, and on the right is a fully mature specimen. Furthest right is the collapsed and decaying trunk of a mature tree, a contribution the biomassy that will eventually become the oil, coal and natural gas we exploit today — The First Trees on Earth - Artist View - First Trees - Artist view - 385 million years ago, in the upper Devonian, the first trees began to appear on Earth. In this illustration, the archaeopteris, considered the first tree, is present at different stages of its evolution, with on the left a young specimen of 6 metres, in the centre a tree twice as large, on the right, an even older specimen. At the extreme right, a strain of an old Archaeopteris collapse. 385 million years ago, near the end of the Devonian period, the first trees began to populate the Earth. Considered the first modern trees, the Archaeopteris were a part of the Earth's primitive forests for the next 25 million years. Unlike the trees we know today, Archaeopteris was in fact a primitive fern that reproduced by means of spores instead of seeds.

A ring of rocks and dust is orbiting the Earth. The massive continent below is Pangee and the ocean to the west is Panthalassa. This is what Earth was supposed to look like at the end of Permian, about 260 million years ago, before the first dinosaurs appeared. This ring around the Earth was of earthly origin, constitutes debris thrown into orbit by collision with a meteorite or comet. Over time, these debris have fallen or fallen to Earth in a meteorite rain - A dusty ring arc orbits four thousand miles above Earth's equator. The massive continent below is Pangea and the ocean to the west is Panthalassa. This is how the Earth may have appeared during the end of the Permian period, a time just prior to the appearance of the dinosaurs, when continental drift was pulling Pangea apart into the seven continents we know today - 260 million years ago the Earth may have been host to ring arcs similar to the incomplete rings that currently circumscribe the planet Neptune . Unlike Neptune's rings, the ring arcs around the Earth were of terrestrial origin, debris thrown into orbit by a collision with a large meteorite or comet. The debris consisted of tiny pebbles that were once molten droplets of ejecta, long since cooled in the vacuum of space. The orbit of the ring arc would eventually decay, returning the debris back to Earth as a shower of meteorites. This debris is found on Earth's surface today in the form of dark, glassy objects known as tektites.: La Terre à la fin du Permien - Ring arcs over the Permian Earth — A ring of rocks and dust is orbiting the Earth.

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

Such high oxygen levels may help to explain why so many terrestrial invertebrates - - insects, arachnids and some crustaceans - - grew to such enormous sizes. These invertebrates “” breathe”” by adsorbing oxygen directly through their skin. Another consequence of such an oxygen - rich environment would be an increased propensity for organic matter to combust.

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 — Cotylorhynchus - Cotylorhynchus was a large mammalian reptile (Synapside, Pelycosaur) living herbivorous from early Permian to mid-Permian (299 to 265 million years).

Meduses - Artist's view - A smack of jellyfish - Illustration of jellyfish swimming in the Panthalassic Ocean, about 500 million years ago in the Cambrian. A smack, or swarm, of jellyfish swim the Panthalassic Ocean 500 million years ago during the Cambrian Period. Jellyfish, AKA sea jellies, are free - swimming organisms from the phylum Cnidaria and may have been among the first mobile macro life forms to evolve on Earth. Their distinguishing feature is specialized cells that they use mainly for capturing prey. Their bodies consist of a non - living jelly - like substance, sandwiched between two layers of tissue that are mostly one cell thick. There are approximately 9,000 species of Cnidaria today

Eogyrinus - Eogyrinus was one of the largest tetrapods of Carbonifere. It could reach 4.6m in length. His fossils were found in England. He was part of the Anthracosaur amphibian group that survived as far as Permian. It is believed that these amphibians were the ancestors of the group from which the reptiles were derived.

Doryaspis (AKA Lyktaspis) was armored with bony spines and a long snout that had spines set along its length (somewhat like the “” saw””” of a modern sawfish). Doryaspis 'mouth opened above, rather than below, the snout and is believed to have dined on plankton, however the snout may have been used to stir up small crustaceans from the mud or sand. In addition to a variety of anemones are palm-like crinoids (class Crinoidea), pentagonal-shaped sea stars, nautilus-like ammonites, and squid-like nautiloid cephalopods of the genus Orthoceras

It looked like a daisy about 2.5 cm. Resembling modern flowers, species of the genus Dinomischus populate the ocean floor about 505 million years ago. About four inches tall, Dinomischus was an animal permanently attached to the ocean floor by a stalk. It probably fed by filtering the surrounding seawater for nutrients, and may have created a current to facilitate this. Its mouth and anus were positioned side - by side
