Dunkleosteus and Cladoselache - Dunkleosteus & Cladoselache - A Dunkleosteus approaches a Cladoselache, the ancestor of sharks. Dunkleosteus, formerly called Dinichthys, is a large fossil placoderm. He lived in the Upper Devonian, between 415 and 360 million years. The largest representatives of the genus were approximately 8-10 m long and weighed around 5 tonnes. These fish were probably the greatest marine predators of their time. A 30-foot-long, four-ton hypercarnivorous apex predator of the species Dunkleosteus terrellix is about to make a meal of a six-foot-long primitive shark of the genus Cladoselache 370 million years ago in the Rheic Ocean near what is today North America. Dunkleosteus terrellix was one of the largest arthrodire placoderms ever to have lived. Almost as long as a school bus, It was heavily armored and therefore likely a relatively slow, but powerful swimmer. There are four Cladoselache/primitive sharks in this image. The schooling fish are generic representativ

Archegosaurus - Archegosaurus in a swamp in Europe 285 million years ago. Archegosaurus was a large, 3m long amphibian living in Permian. Ten-foot-long temnospondyl amphibians of the genus Archegosaurus lounge in an Early Permian swamp 285 million years ago in what is today Western Europe. Also in this image are several varieties of fern including tree-like seed ferns of the genus Alethopteris. Archegosaurus was a large, crocodile-like carnivore that likely fed upon fish and perhaps other amphibians

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

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

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

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

Pterosaurs - Pterosaurs amidst Bjuvia - A Pterosaur approaches an appetizing carcass 228 million years ago. A pterosaur alights near the bank of a shallow pond, attracted by the prospect of a tasty dinner of carrion. 228 million years ago the Earth's open and sunny plains were home to a type of cycad known as Bjuvia simplex. Bjuvia, a cone-bearing seed plant, resembled modern palms, however they were more closely related to pines. Adult Bjuvia grew to a height of 25 feet and became extinct about 210 million years ago during the late Triassic period. Also during this time the skies were home to a flying variety of reptiles known as pterosaurs. While pterosaurs' reptilian origins appear clear, they were not related to birds, and it isn't certain whether they were even related to dinosaurs. There were many varieties of pterosaur during their reign of 160 million years, becoming extinct, along with most of the dinosaurs, about 65 million years ago

Stegosaur and allosaur - Allosaurus meets Stegosaurus - Meeting between an allosaurus (allosaurus, carnivorous dinosaur) and a stegosaur (stegosaurus, herbivore dinosaur) in a Jurassic forest. The stegosaur moves back by walking on a pachypteris, causing a little lezard to escape. An Allosaurus stumbles upon a grazing Stegosaurus in a Jurassic Redwood forest. While it's probable that the 30 foot, 2 ton Allosaurus preyed upon large herbivores, I doubt that one would have risked a direct confrontation with an adult Stegosaurus, which could weigh as much as 5 tons and wields a powerful tail tipped with 3-foot spikes. Adding to its survivability, Stegosaurus 'front legs may have been strong enough to allow it to pivot and swing its entire backside around to ward off an assault. In addition to Redwoods and varieties of fern, this Jurassic-period forest includes the now extinct Pachypteris, an arboreal plant that grew to a height of 10 feet and populated every major continent 160 million yea

Dimorphodon - Close up of a Dimorphodon on the edge of the ancient Tethys Ocean. Dimorphodon (Dimorphodon macronyx) is a pterosaur belonging to the family dimorphodontidae and living in the lower Jurassic, between 200 and 180 million years. He had a beak like a puffin. The dimorphodon was about 1 metre long, with a wingspan of 1.4 metres. A close-up of a colorful large-billed Dimorphodon from Early-Jurassic England 195 million years ago. In the background is the ancient Tethys Ocean. While Dimorphodon's coloration is unknown, here an adult male has been given a colorful inspired by modern day puffins and toucans. Dimorphodon was a medium-sized pterosaur (flying reptile) with a wingspan of about four feet and a large head and puffin-like “” beak.”” Its long front teeth suggest that it was built for plucking fish from near the surface of the water. Its head and beak combined were about 9 inches long

Sunrise seen from Triton - Artist view - Sunrise on Triton - Artist view - Sunrise seen from Triton, the largest satellite in Neptune. A diminutive sun rises over Triton's hard and glistening landscape of rock, frozen water, carbon dioxide, nitrogen, and methane. The little warmth that reaches Triton's surface induces a nitrogen and methane haze, forming a very tenuous atmosphere. It is very cold on Triton with temperatures falling as low as minus 391o F. While as much as 25% of Triton may be composed of water ice, it is very unlikely that there is any liquid water, or life, on this world

Also in this image, on the lower right is a snake - like, legless amphibian from the genus Ophiderpeton. Flying overhead and resembling a giant dragonfly is a prehistoric insect from the genus Meganeura. The tree - like plants making up the surrounding forest include Sigillaria scutell

Ocean level rise - West Hemisphere - Earth's Western hemisphere with sea level+100m - Artist's view showing North and South America as they would appear if ocean levels increased by 100 metres. This would happen if all glaciers on Earth melt. This is how the Earth's Western hemisphere may appear with mean sea level about 100 meters (330 feet) above today's. Such a dramatic rise in sea level could occur if all of the Earth's glaciers were to melt. In this image the Gulf of Mexico and Atlantic ocean have inundated almost all of southeastern United State including the entire state of Florida, almost all of Louisiana, and significant portions of the other southeastern states and the District of Columbia. Major US cities submerged include New York City, Boston, and Houston, and on the west coast Los Angeles, San Francisco, and much of San Diego. In addition to land claimed from the United States this 100 meter rise in sea level has also claimed much of Central America including the Yucatan

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

Earth 90 million years ago - Artist's view - Late Cretaceous Earth - Earth seen in the upper cretace, about 90 million years ago. This is how the western hemisphere of the Earth may have appeared 90 million years ago during the Late Cretaceous period. During this period continental drift, driven by the massive forces of plate tectonics, had broken the supercontinent of Pangea into Laurasia in the north and Gondwana in the south. With a climate much warmer than today's there were no frozen polar caps and the resulting high ocean levels submerged a third of today's landmasses under warm shallow seas creating numerous waterways and “” island””” continents. In this image much of the incipient North American continent is divided by the Western Interior Seaway, the Isthmus of Panama is submerged by the Proto - Caribbean Sea, and the Pacific Ocean is making an incursion into South America

This is how the Indian subcontinent may have appeared 70 million years ago during the Late Cretaceous period. Looking north, immediately to India's west is the island continent of Madagascar and further west is the eastern coast of southern Africa. In the distant past India and Madagascar formed a single continent, however India was part of a separate tectonic plate that subsequently began to drift northward. This northward motion (covering about 8 inches per year making it among the fastest on the Earth's lithosphere) split India from Madagascar and carried it north across the Tethys Ocean until it collided with Eurasia about 50 to 35 million years ago. This collision between the Indian and Eurasian plates joined India to South Asia and created the Tibetan Plateau and the Himalaya Mountains

From its surface, its star, about 100 times less bright than our Sun, must be large in the sky because of its proximity to the planet. In April 2007 the Geneva Observatory in Switzerland announced the discovery of a “super - earth”” extrasolar planet orbiting the red dwarf star Gliese 581. Dubbed Gliese 581 c, it's been called a super - earth because it is one of the few known extrasolar planets that has a mass near Earth's, and the only one to occupy its sun's “” habitable zone.”” Gliese 581 c is believed to be about five times more massive than the Earth with a diameter about half - again as large as Earth's. Depending upon the planet's composition, whether mostly rock or a combin

Gl 581c: discovery of a habitable planet - Gl 581c: discovery of an habitable planet - Artist's view of the exoplanet Gliese 581c. Gliese 581c, with a radius of 1.5 times that of the Earth, is the first exoplanet gathering the necessary elements to imagine the existence of a possible extra-terrestrial life.

Jupiter seen from its satellite Europe - Illustration - Jupiter & Io from Europa's surface - Illustration - Jupiter and Io seen from the ice surface of the satellite Europe. The surface of Europe is about five times brighter than our Moon. A crescent Jupiter hovers near the horizon along with Jupiter's volcanic satellite Io. In the foreground a meandering crevasse cleaves Europa's icy surface, one of thousands that crisscross this moon's exceedingly flat and bright exterior. The surface of Europa is about five times brighter than our own Moon and is so flat that no feature rises more than 3,000 feet

Lava lake on Io - Illustration - Lava lake on Io - Artist's view of a lava lake on the surface of Io, one of Jupiter's satellites. There are places on Io where molten lava has been observed actively welling up from beneath the surface of this otherwise frozen world. Lavas on Io were originally thought to be molten sulfur, but with caldera temperatures far exceeding 1,000o F - - too hot for liquid sulfur - - these eruptions are now thought to be primarily molten silicate rocks. In this image a dormant volcanic caldera re - awakens with a surge of new lava that breaks up and melts a frozen crust. A gibbous Jupiter hangs over the horizon

Ice on the Moon - Illustration - Lunar ice - Illustration - Artist's view of ice on the surface of a crater that remains perpetually in the shade of the Sun, near the poles. Water from an encounter with an icy comet has collected in the perpetual shade of a deep crater where the temperature is a constant - 380o F. In 1998, the unmanned Lunar Prospector probe discovered evidence for water ice on the surface of the moon. Some scientists believe that as much as 10 to 300 million tons of ice may reside at the moon's North and South poles. The source of the ice is thought to be from one or more comets that struck the moon's surface four billion years ago. (It is thought that Earth's water may have come from comets as well.) Unfortunately, the moon's small size and lack of an atmosphere caused it to lose almost all of its accumulated water to space. Any water that does remain on the moon would likely be on the poles, hidden in craters and depressions shaded from the Sun

Brown dwarf star Gliese 229 b - Brown dwarf Gliese 229 b - Artist view of the brown dwarf star Gliese 229B. Discovered in 1995 in the constellation Lievre at 18 years - light from Earth, this brown dwarf is 30 to 40 times more massive than Jupiter and is estimated to be 2 to 4 billion years old. Top left is the red dwarf star Gliese 229A. This is how the brown dwarf Gliese 229b might appear from a distance of about a half million miles. Glowing like a charcoal ember, Gliese 229 b was discovered in 1995 and is 19 light years from the Earth. This brown dwarf orbits the red dwarf Gliese 229A in the constellation Lepus. Gliese A can be seen shining dimly on the upper left. These two dwarfs are about four billion miles apart, about the same distance between Pluto and our sun. Gliese 229 b is believed to be 30 to 40 times more massive than the planet Jupiter, which is massive enough for Gliese 229 b to sustain deuterium fusion, but not enough mass to initiate hydrogen fusion like our Sun.
