PIX4661176: Mount Everest seen from space - Himalaya Mountains, Nepal March 1996 - Part of the Himalayan chain with Mount Everest (below the center, on the left), observed by the shuttle Atlantis in March 1996. At the top of the picture, the foggy plains of northern India, at the bottom the Tibetan plateau. The Himalaya Mountains provide a formidable physical barrier between the hazy environmental conditions of north central India (top) and Nepal (middle), and the clear atmosphere of the Tibetan Plateau (lower third of image). Elevation disparities in this region of the world are tremendous. For example the elevations on the Gangetic Plain in India averages about 300 feet (92 meters) above sea level, the foothills (dark - looking features that run laterally across the image) in Nepal average about 2500 feet (762 meters), and finally the snow capped Himalayas average around 24000 feet (7315 meters). Mt. Everest, highest mountain peak in the world at 29028 feet (8848 meters), is visible as an identifiable bright feature (slightly below and left of center). Several east - west aligned fault valleys (result of tectonic forces - collision of plate boundaries) are visible on the sparsely vegetated Tibetan Plateau (China) where the average valley elevation is 15000 feet (4572 meters) above sea level. A small section of the easterly draining Brahmaputra River can be discerned near the lower right corner of the image / Bridgeman Images
PIX4676186: Miscanti lagoon. Chile - Laguna Miscanti. Chile - The Miscanti Lagoon is situated at 4200 metres above sea level in the Andes Mountains, about 120 kilometres from San Pedro de Atacama. The lagoon is dominated by the Miscanti volcano, whose snow summit reaches 5622 metres above sea level. Laguna Miscanti is a water lake located in the altiplano of the Antofagasta Region, in northern Chile. Cerro Miscanti tower over this lake / Bridgeman Images

PIX4677032: Eruption of the volcano Semeru night view - Semeru volcano at night - Eruption of the volcano Semeru in June 2008 night view. This explosive active volcano is 3676 metres from the highest point of the island of Java in Indonesia. It's a stratovolcano located on the Pacific belt of fire. Volcanic eruption of Semeru seen at night in june 2008. This active volcano is located in Indonesia on the Pacific Ring of fire. With an elevation of 3676 meters, this stratovolcano is the tallest mountain on the island of Java / Bridgeman Images
PIX4661665: Dimetrodons by a lake - Dimetrodon lakeside - View of an artist of dimetrodons in a Permian landscape. Dimetrodon is a mammalian reptile (Therapside), carnivore living in Permian. A pair of carnivorous Dimetrodon explores an Early Permian landscape. The tree on the left is a Corodite, an ancient ancestor of today's conifers, and on the far right is a Glossopteris, a seed plant that came to dominate this period with over 70 different species / Bridgeman Images
PIX4661669: 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 representatives of the class Actinopterygii, a sub-class of the bony fishes which emerged about 420 million years ago, while the sea jellies are generic representatives of the subphylum Medusozoa / Bridgeman Images
PIX4661737: 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 / Bridgeman Images
PIX4661943: Allosaurus among the sequoias - Allosaurus amidst Sequoias - A couple of allosaurus (allosaurus, carnivorous dinosaur) foraging in the middle of a sequoia forest. The adult male allosaur is recognizable with its orange “” horns””. For 5 million years, allosaurs were the most frequent carnivores in North America. A pair of Allosauruses search for dinner in the pre-twilight of a lush mountainside forest. The orange “” horns”” on the foreground Allosaurus identifies this as an adult male, while his female companion behind attempts to make a meal of an unfortunate terrapin. 150 million years ago during the late Jurassic period, giant Sequoias - also known as Redwoods - may have populated all of the northern continents. These evergreens grow as tall as 370 feet and some have trunk diameters exceeding 25 feet. The only living Sequoias today - and some are over 2,000 years old - occupy a narrow strip of land along the North American Pacific coast. Also during the late Jurassic, a large, carnivorous dinosaur known as Allosaurus is likely to have hunted in the shade of the first Sequoias. For 5 million years Allosaurus was the most common large carnivore in North America. Growing as long as 40 feet and weighing up to two tons, this fierce predator probably had few, if any rivals / Bridgeman Images
PIX4662392: Suchomimus - Suchomimus (crocodile mime) was a large carnivorous dinosaur with a jaw similar to that of a crocodile, living in the middle of the cretace 110 to 120 million years ago. 12 feet tall and weighing five tons, a carnivorous Suchomimus wanders a beach on the ancient Tethys Ocean 115 million ago in search of her next meal. A ferocious predator nearly as big as T-Rex with a crocodile-like head, Suchomimus (“crocodile mimic”) may have lived largely on fish and carrion in what today is Northern Africa / Bridgeman Images
PIX4677507: Eruption de la Soufriere - Ile de Montserrat - Volcanic eruption of Soufriere Hills - Montserrat - Eruption of the Soufriere volcano on the island of Montserrat in the Caribbean, seen from the International Space Station (ISS) on October 11, 2009. The Soufriere Hills, a volcano on the island of Montserrat, in the Lesser Antilles island chain in the Caribbean Sea, has been active since 1995. This oblique astronaut photograph from the International Space Station (ISS) captures a white-to-gray ash and steam plume extending westwards from the volcano on October 11, 2009. While much of the island is covered in green vegetation, gray deposits that include pyroclastic flows and volcanic mudflows (lahars) are visible extending from the volcano towards the coastline. The silver-gray appearance of the Caribbean Sea surface is due to sunglint, which is the mirror-like reflection of sunlight off the water surface back towards the handheld camera onboard the ISS. The sunglint highlights surface wave patterns around the island / Bridgeman Images
