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
PIX4662983: Nedoceratops and White Rhinoceros - Comparison - Nedoceratops & White Rhinoceros compared - An adult Nedoceratops (Diceratops) who lived 70 million years ago is compared to today's adult white rhinoceros (Ceratotherium simum). The Nedoceratops was 2.5 metres high at the withers and weighed 5.4 tons, while the white rhinoceros was 1.8 metres high at the withers and weighed 3.2 tons. An adult Nedoceratops (FKA Diceratops) from 70 million years ago is compared to a modern adult White Rhinoceros (Ceratotherium simum). The Nedoceratops is a little over 8 feet tall at the shoulder and weighs 12,000 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
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
