Fear of crocodiles (deinosuchus) Such a huge four-legged predators are terrestrial crocodiles after the Cretaceous period of a giant. Body length of about fifteen meters. Today, fear of crocodiles in the size of three times the largest crocodile, its name is "terrible crocodile" means. It lives in swamps, quietly waiting there, from here after killing the dinosaurs. It lives in the Late Cretaceous North America. Length: There may be 15 meters long Category: Crocodile Variety: d. hatcheri (type) d. riograndensis d. rugosus Fear of alligators living in sixty-seven million years ago, the body length of up to 12-15 meters, is the largest ancient crocodiles kind of predator, and it can be contemporary of the dinosaurs. Fear of crocodiles (denosuchus) die - noh - sook-uhs Name meaning: "terrible crocodile" Age: 65 million years ago Fossil Location: North West Size: body length 15 meters One of the largest carnivores to date, compared with its The largest carnivorous dinosaur contemporaries violent Tyrannosaurus Rex even longer. It may eat dinosaurs Mesozoic biosphere is not fully dominated by the dinosaurs --- Whether in the general public's impression, or in the eyes of paleontologists, dinosaurs dating back millions of years ago, the Mesozoic are worthy of the earth king. Recently, however, a team composed of 12 paleontologists expedition, the Amazon basin in northern Peru have found a body length of up to 13 meters and weighing up to 9 tons, the general length as the super giant bus. All kinds of people in the excavated dinosaur fossils, including abnormal fierce, invincible predator who have found the fatal wounds left by the giant. Formed about 1.1 billion years ago, the Cretaceous, giant is well deserved, "the king of predators." Amazon basin of Peru found 13 meters long giant fossil. The summer of 2005, a paleontologist from the 12 expedition composed of the Amazon basin in northern Peru to conduct investigations. Local lush forests, rivers, clouds, hot and humid air anomaly is an inaccessible rainforest. But this environment is the eyes of paleontologists "heaven", a variety of ancient animals and plants can grow freely here, has witnessed a touching scene endless. Amazon is the world's most famous crocodile produced where the blunt fierce crocodiles and alligators are there wide hegemony. Expedition in the woods wearing a patrol carefully to avoid those terrible disturb neighbors. Expedition also spell out the crocodile with these fossil skull: 1.3 meters long, the teeth will have 5 cm long. According to the crocodile head and body length ratio, paleontologists speculate that this giant can reach 13 meters in length, body width 2.5 meters, the largest crocodile in modern 10 to 15 times the weight of 9 tons, the ferocious Tyrannosaurus Rex but also heavy 1 ton. The crocodile's teeth and did not aging, estimated that it should also be able to continue to grow until 16 to 20 meters long. Because reptiles increased with age, body length increase is almost unlimited. Super giant killer is cruel, it can tear the body of T. rex. Salas also said that this rare forest in the Amazon should be able to prove that, it was the Amazon jungle inland, perhaps connected with the Caribbean. He also gave us paint this: the huge 13-meter-long crocodile hidden in the huge lake side, like a tiger, ready to go. A group of dinosaurs is carefully next to drinking water. Suddenly, the giant jaws open, fast to swoop on its prey, sharp teeth instantly pierced the giant dinosaur hard skin ... ... Giant fossils have been repeatedly found in the world. They believe that only the absolute horror of the giant reptiles living in the mid-Cretaceous, 110 million years ago to 9000 million years, but it is not the direct ancestors of modern crocodiles, but only close relatives. The prototype of the modern crocodilians animals appeared 230 million years ago, the late Triassic Mesozoic, and then differentiated into many types. In the early Jurassic period, they differentiate into two completely different, one in the water, one on land. Giant fossil history of the evolution of a unique value. Columbia State University paleontologist Kuwait Merle Davis said: super giant fossils of prehistoric creatures on Earth can be less in the archaeological history of the discovery of dinosaur fossils. This major discovery in the history of biological evolution to make up the Earth's long history of crocodilians gaps help to help the evolution of human history on earth to do a deeper understanding.

Chinese name: fear of crocodiles Latin name: Deinosuchus (戴诺苏克斯) Name meaning: "giant of terror" Survival Age: Late Cretaceous of North America, since about 80 million to 73 million years ago Subspecies: D. hatcheri (type species) D. riograndensis D. rugosus -------------------------------------------------- ---------------------------- Fear of crocodiles (scientific name: Deinosuchus), is an extinct large crocodiles, alligators are super-families, lived in the Late Cretaceous of North America East Coast region. Fear of crocodiles in the Greek context of the generic name for the "giant of terror", δεινός / deinos means "terrorist", σουχος / suchos meaning "crocodile." Although the fear of crocodiles in length have different estimates, but their size was larger than any existing crocodiles. Even the smallest estimate, and its weight is still greater than any existing crocodiles. The history of fear of crocodiles is considered to be one of the largest crocodile. Other prehistoric giant crocodiles include: Early Cretaceous crocodile emperor muscle muscle Africa species, Miocene of Brazil Brazil Bruce crocodile species, Miocene and Pliocene crocodile India beak. Habitat Fear of crocodile fossil found in many areas, mainly in the United States, including Alabama, Mississippi, Montana, Georgia, New Jersey, North Carolina, New Mexico, Texas, Utah and Wyoming. In 2006, a fear of crocodiles in northern Mexico found within the skin into the bone, the first fruit in the U.S. fear of crocodile fossils found outside. The most common fear of fossil crocodile of the Gulf Coast in Georgia found in plain areas, near the Alabama border. According to the fossil distribution of fear of crocodiles, these giant could survive in the estuarine environment. Some of the fear of crocodile fossils have been found in marine sediments, but may be fear of crocodiles into the sea in search of food, as today's crocodile. In A Guha group (Aguja Formation), some of the fear of crocodiles can survive in the salt marsh or tidal zone, the area also found that the biggest fear of crocodile fossils. And the fear of crocodile habitat Albert off with the dragon, is a 9-meter-long theropod dinosaurs, T. rex and other giant may also be predators in before the advent of the food chain on land at the top, and the fear is likely to crocodile conflict. Feeding habits In 1954, the first time 内德科尔伯特 and Roland Bird, fear of crocodiles are likely to live in the same region of the dinosaurs for food.内德科尔伯特 in 1961 reiterated this theory: "The crocodile should be eating dinosaurs, or why they can grow to a size beyond the dinosaurs? Terrorist attack in the water crocodile prey shore, where is the theropod dinosaurs can not hunt the area. " Fear is often considered similar crocodile crocodile hunting mode now, the body immersed in water near the shore of the dinosaur attacks or other terrestrial animals, until the prey drowning. Big Bend National Park in the vicinity of hadrosaur caudal vertebrae found in several sections, with the fear of teeth marks in crocodile, alligator will strengthen the fear of some of the theory of dinosaurs for food. David Shiwei Mo et al: fear of crocodiles may use sea turtles as food. Department of fear of alligators may be back-mouth, blunt teeth, crush turtle shells to sea turtles for food. In the fear of crocodile fossils found in eastern North America Department, often find the side necked turtle fossil suborder Bothremydidae Division, a number of turtle shells have been found of such indentation, most likely left by a large crocodile. In 2002, David Shiwei Mo's diet may be made based on fear of crocodiles living in different areas, but there are different changes. Living in fear of eastern North America crocodile smaller, niche may be similar to today's alligators, a variety of food sources, such as: turtles, large fish and small dinosaurs. Texas and Montana's fear crocodiles larger, more rare, may be mainly to duck-billed dinosaur and other large dinosaurs for food. David Shiwei Mo also suggested that eastern North America was no body of theropod dinosaurs, crocodiles than fear, so fear of alligators may be the region's top predators. Discovery and Classification In 1858, geologist 埃比尼泽埃蒙 Sri Lanka (Ebenezer Emmons) found in North Carolina Bladen County, two large teeth. Emmons these two teeth classified Polyptychodon, and the establishment of new species P. rugosus, this is a time to be classified as a crocodile, is now the purpose of a genus of Asian dragons. The shape of these two teeth thick, slightly curved, enamel surface with a vertical grooves. These two teeth are the earliest known account of the fear of being scientific crocodile fossils. 1903, 约翰贝尔海彻 Seoul (John Bell Hatcher) and TW Stanton Willow Creek area in Montana, found that a number of fossil bone within the skin. The bone within the skin was initially classified as a Long Long Branch header. In addition to bone formation within the skin, the local also dug up the spine, ribs, pubic bone and other fossils. As more fossils were dug up, Hai Cheer found that these fossils belong to a large crocodile, specializing in the Hai Cheer on the fossils of dinosaurs have lost interest. Hai Cheer died in 1904, WJ Holland continue to study these crocodile fossils. 1909, WJ Holland The establishment of these new fossils are: fear of crocodiles (Deinosuchus), type species Deinosuchus hatcheri, species name is based on fossils found in Hai Cheer name. In 1940, the excavation team of the United States Museum of Natural History in the Texas Big Bend National Park, many large crocodile fossil dig. In 1954, 内德科尔伯特 and Roland Bird published studies of these fossils, called terror crocodile (Phobosuchus riograndensis). In 1979, Donald Baird (Donald Baird) and Jack Horner (Jack Horner) found that fear of terror alligators and crocodiles are the same species, terror crocodile alligator as a synonym of terror. American Museum of Natural History in the reconstruction of the head model, the reference to the head of the Cuban crocodile, and the use of gypsum reconstruct most of the head. Colbert and Bird that this version is too conservative, that if the reference to reconstruct the crocodile, the body can produce a greater fear of crocodiles model. At that time, fear of crocodiles is not clear whether the broad snout, Colbert and Bird, head of computing the proportion of fear of crocodiles when the error occurred. Although the reconstruction error, this fear has become a crocodile head model the general public's first impression of fear crocodiles. In recent years, more fear of crocodile fossils have been discovered. Mostly broken fossils, but help on the fear of crocodiles Paleontology for more research. Christopher A. Brochu suggested that fear of crocodile skin in a unique bone shape, is one of identifying the characteristics of fear of crocodiles. In 2002, David Shi Weimo more fear of crocodile fossils according to construct up to 90% of the full degree of computer models of the head. Colbert and Bird, based on dental characteristics, the fear of crocodiles in the crocodile classified Section. According to Gregory, who in 1999 利艾利克森 proposed phylogenetic studies, fear of crocodile alligator superfamily is the original species.
