LBY4724797: The Great Wall of China is close to Pekin. Construction of the Great Wall began in the 9th and 8th century BC, and continued for more than 2,000 years. If all its constructions and trunks spread across the vast region of North and Central China were combined, the Great Wall would extend over 50,000 km (100,000 li). Indeed, historical records show that since the Fighting Kingdoms, more than 20 feodal states and imperial dynasties have begun building defense walls. Photography 25/10/07 / Bridgeman Images

PIX4662929: Einiosaurus - The Einiosaurs were herbivorous dinosaurs of the cretace, of the same family as the triceratops. A herd of plant-eating Einiosaurus roam the plains in what is today the Two Medicine Formation in northwestern Montana. In the distance a long-dormant volcano signals its return to activity by cauterizing snowcover into great clouds of steam. Within weeks the volcano will bury this scene beneath a massive ash fall, preserving the remains of the flora a fauna for future exhumation and examination by Homo sapiens 75 million years later. Einiosaurus was from the same family as the better known Triceratops. These dinosaurs were about 20 feet long, 6 feet tall at the hips and weighed about 2 tons / Bridgeman Images
PIX4662989: Torosaurus - Torosaurs were herbivorous dinosaurs of the cretace, of the same family as the triceratops. Here, a five-ton male is drinking a river. A five ton, 25 foot long male Torosaurus drinks from a river bordered by ferns and Bald Cypress in what is today southeastern Wyoming. Torosaurus was a plant-eating dinosaur from the same family as the better known Triceratops. Torosaurus had one of the largest skulls of any known land animal, reaching over 8 feet in length / Bridgeman Images
PIX4662994: Torosaurus and White Rhinoceros - Comparison - Torosaurus & White Rhinoceros compared - An adult Torosaurus who lived 75 million years ago is compared to today's adult white rhinoceros (Ceratotherium simum). The Torosaurus was 2 metres high at the withers and weighed 4.5 tonnes, while the white rhinoceros was 1.8 metres high at the withers and weighed 3.2 tonnes. An adult Torosaurus from 75 million years ago is compared to a modern adult White Rhinoceros (Ceratotherium simum). The Torosaurus is 6 and a half feet tall at the shoulder and weighs 10,000 pounds*, while the White Rhinoceros is 6 feet tall at the shoulder and weighs 7,000 pounds.* Values are estimates only based upon available paleontological data / Bridgeman Images
PIX4663332: Marine predators of the cretace - Cretaceous marine predators - Artist's view showing three marine predators that evoluted in the inland sea of North America 75 million years ago. From left to right there is an invertebra pursued by a 1.2 metre Enchodus, followed by a 5 metre Dolichorhynchops followed by an 18 metre Mosasaurus. Three primary marine predators that shared the ocean waters of the Western Interior Seaway of North America 75 million years ago are illustrated here. Left to right is a non-descript invertebrate pursued by a 4 foot long Enchodus, followed by a 17 foot long Dolichorhynchops, followed by a 55 foot long Mosasaur / Bridgeman Images
PIX4663447: Elasmosaurus - Artist's view of two Elasmosaurus, of the great marine reptiles of the cretace, swimming under the gaze of Ichthyornis. A pair of 40-foot-long Elasmosaurus engage in a swimming courtship dance in a secluded pool 80 million years ago in what is today North America. The gull-like birds are Ichthyornis, the Cretaceous ecological equivalent of modern seabirds such as gulls, petrels, and skimmers. At over two tons, Elasmosaurus was an air-breathing carnivorous reptile with flippers for limbs and a relatively small head with sharp teeth. More than half of its length was neck which had more than 70 vertebrae, more than any other animal / Bridgeman Images
PIX4663577: Antarctosaurus stalked by an Abelisaurus - Antarctosaurus stalked by Abelisaurus - An Abelisaurus (Abelisaurus) chases a young Antarctosaurus in a forest in Argentina. A 30-foot-long, 10 ton juvenile titanosaurian sauropod dinosaur of the genus Antarctosaurus is approached from behind by a 25-foot-long, two ton adult abelisaurid theropod dinosaur of the genus Abelisaurus deep in a forest in what is today Argentina. Likely a fierce predator, Abelisaurus resembled the larger Tyrannosaurus Rex that was to roam North America 10 million years later. Antarctosaurus was an herbivore that may have grown to 60 feet long and weighed up to 100 tons. Antarctosaurus had a squarish, blunt head with peg-shaped teeth / Bridgeman Images
PIX4634712: Uranus and three satellites seen by Voyager 2 - Image obtained by the Voyager 2 probe in January 1986 showing the planet Uranus accompanied by the satellites Ariel (top right), Miranda (closest to the planet) and Umbriel (bottom left). This Voyager photograph of Uranus taken in january 1986 is a composite of for images taken by the narrow angle camera. At this range, clouds and other features in the atmosphere as small as 1,370 km. could be detected by Voyager 2. Yet, no such features are visible. This view is toward the illuminated south pole of Uranus. The predominant blue color is the result of atmospheric methane, which absorbs the red wavelengths from incoming sunlight. The spot at the upper left edge of the planet's disk reulted from the removal of a network mark used in making measurments on the photograph. Three of Uranus' five known satellites are visible; Miranda (at far right, closest to the planet), Ariel (next out, at top), and Umbriel (lower left). Titania and Oberon are now outside the narrow angle camera's field of view when it centered on the planet. This color composite was made from images taken through blue, green, orange, and clear filters / Bridgeman Images
PIX4635257: Venus by Magellan: part of Bereghinya Planitia - Plain of the hemisphere north of Venus. The image covers an area 260 km wide by 330 km high. You can see ancient terrain (upper right and lower left), as well as more recent lava flows associated with the Tepev Mons volcano located below the image / Bridgeman Images

PIX4664037: Late Cretaceous Fauna - Late Cretaceous Fauna - Late Cretaceous Fauna. On the banks of the inner sea of Niobraran, a Parasaurolophus walkeri approaches to drink. In the sky and on the bank, Ichthyornis. Far in the sky, a pterosaur (azhdarchidae) spotted a carcass of Brachylophosaurus canadensis on the bank. On the right a Leidyosuchus canadensis. Montana during the late Cretaceous. Near the shores of the Western Interior Seaway, a Parasaurolophus walkeri bellows a call, while an Ichthyornis dispar stands on the foreground sand (and flies in from above) at a safe distance from the crocodilian Leidyosuchus canadensis. In the distance, the decaying carcass of a Brachylophosaurus canadensis has attracted a huge azhdarchid pterodaur / Bridgeman Images
PIX4664384: Brontotheres and birds - Brontotherium with birds - Artist's view of Brontotheres (Brontotherium) in a landscape of South Dakota 35 million years ago. Brontotherium wander the lush Late Eocene landscape of South Dakota 35 million years ago. Modern rhinoceroses have a symbiotic relationship with birds (variously known as oxpeckers or tick birds) that eat parasites they find on the rhino's skin and noisily warn of danger. No doubt similar symbiotic relationships existed between birds and the megafauna of the Eocene / Bridgeman Images
