If the bone was not re-deposited into that stratum by weathering action, it would provide evidence that some dinosaur populations may have survived at least a half million years into the Cenozoic. Similar reports have come from other parts of the world, including China. Dinosaur fossils have been known for millennia, although their true nature was not recognized.
The Chinese considered them to be dragon bones and documented them as such. Scholarly descriptions of what would now be recognized as dinosaur bones first appeared in the late 17th century in England. Part of a bone, now known to have been the femur of a Megalosaurus ,  was recovered from a limestone quarry at Cornwell near Chipping Norton , Oxfordshire, in He therefore concluded it to be the femur of a giant human similar to those mentioned throughout the ages.
Between and , the Rev William Buckland , the first Reader of Geology at the University of Oxford, collected more fossilized bones of Megalosaurus and became the first person to describe a dinosaur in a scientific journal. Gideon Mantell recognized similarities between his fossils and the bones of modern iguanas. He published his findings in The study of these "great fossil lizards" soon became of great interest to European and American scientists, and in the English paleontologist Richard Owen coined the term "dinosaur".
He recognized that the remains that had been found so far, Iguanodon , Megalosaurus and Hylaeosaurus , shared a number of distinctive features, and so decided to present them as a distinct taxonomic group. With the backing of Prince Albert , the husband of Queen Victoria , Owen established the Natural History Museum, London , to display the national collection of dinosaur fossils and other biological and geological exhibits. In , William Parker Foulke discovered the first known American dinosaur, in marl pits in the small town of Haddonfield, New Jersey.
https://itlauto.com/wp-includes/secret/3502-comment-pirater-les.php Although fossils had been found before, their nature had not been correctly discerned. The creature was named Hadrosaurus foulkii. It was an extremely important find: Hadrosaurus was one of the first nearly complete dinosaur skeletons found the first was in , in Maidstone, England , and it was clearly a bipedal creature.
This was a revolutionary discovery as, until that point, most scientists had believed dinosaurs walked on four feet, like other lizards. Foulke's discoveries sparked a wave of dinosaur mania in the United States. Dinosaur mania was exemplified by the fierce rivalry between Edward Drinker Cope and Othniel Charles Marsh , both of whom raced to be the first to find new dinosaurs in what came to be known as the Bone Wars.
The feud probably originated when Marsh publicly pointed out that Cope's reconstruction of an Elasmosaurus skeleton was flawed: Cope had inadvertently placed the plesiosaur's head at what should have been the animal's tail end. The fight between the two scientists lasted for over 30 years, ending in when Cope died after spending his entire fortune on the dinosaur hunt. Marsh 'won' the contest primarily because he was better funded through a relationship with the United States Geological Survey. Unfortunately, many valuable dinosaur specimens were damaged or destroyed due to the pair's rough methods: for example, their diggers often used dynamite to unearth bones a method modern paleontologists would find appalling because the explosions from the dynamic would potentially destroy any and all dinosauric evidence.
Despite their unrefined methods, the contributions of Cope and Marsh to paleontology were vast: Marsh unearthed 86 new species of dinosaur and Cope discovered 56, a total of new species. After , the search for dinosaur fossils extended to every continent, including Antarctica. The first Antarctic dinosaur to be discovered, the ankylosaurid Antarctopelta oliveroi , was found on James Ross Island in ,  although it was before an Antarctic species, the theropod Cryolophosaurus ellioti , was formally named and described in a scientific journal.
Current dinosaur "hot spots" include southern South America especially Argentina and China. China in particular has produced many exceptional feathered dinosaur specimens due to the unique geology of its dinosaur beds, as well as an ancient arid climate particularly conducive to fossilization. The field of dinosaur research has enjoyed a surge in activity that began in the s and is ongoing. This was triggered, in part, by John Ostrom 's discovery of Deinonychus , an active predator that may have been warm-blooded, in marked contrast to the then-prevailing image of dinosaurs as sluggish and cold-blooded.
Vertebrate paleontology has become a global science. Major new dinosaur discoveries have been made by paleontologists working in previously unexploited regions, including India, South America, Madagascar, Antarctica, and most significantly China the amazingly well-preserved feathered dinosaurs  in China have further consolidated the link between dinosaurs and their living descendants, modern birds.
The widespread application of cladistics , which rigorously analyzes the relationships between biological organisms, has also proved tremendously useful in classifying dinosaurs. Cladistic analysis, among other modern techniques, helps to compensate for an often incomplete and fragmentary fossil record. One of the best examples of soft-tissue impressions in a fossil dinosaur was discovered in the Pietraroia Plattenkalk in southern Italy. The discovery was reported in , and described the specimen of a small, very young coelurosaur, Scipionyx samniticus.
The fossil includes portions of the intestines, colon, liver, muscles, and windpipe of this immature dinosaur. In the March issue of Science , the paleontologist Mary Higby Schweitzer and her team announced the discovery of flexible material resembling actual soft tissue inside a million-year-old Tyrannosaurus rex leg bone from the Hell Creek Formation in Montana. After recovery, the tissue was rehydrated by the science team. Scrutiny under the microscope further revealed that the putative dinosaur soft tissue had retained fine structures microstructures even at the cellular level.
The exact nature and composition of this material, and the implications of Schweitzer's discovery, are not yet clear. In , a team including Schweitzer announced that, using even more careful methodology, they had duplicated their results by finding similar soft tissue in a duck-billed dinosaur , Brachylophosaurus canadensis , found in the Judith River Formation of Montana. This included even more detailed tissue, down to preserved bone cells that seem even to have visible remnants of nuclei and what seem to be red blood cells.
Among other materials found in the bone was collagen , as in the Tyrannosaurus bone. The type of collagen an animal has in its bones varies according to its DNA and, in both cases, this collagen was of the same type found in modern chickens and ostriches. The extraction of ancient DNA from dinosaur fossils has been reported on two separate occasions;  upon further inspection and peer review , however, neither of these reports could be confirmed.
By human standards, dinosaurs were creatures of fantastic appearance and often enormous size. As such, they have captured the popular imagination and become an enduring part of human culture. Entry of the word "dinosaur" into the common vernacular reflects the animals' cultural importance: in English, "dinosaur" is commonly used to describe anything that is impractically large, obsolete, or bound for extinction.
Public enthusiasm for dinosaurs first developed in Victorian England, where in , three decades after the first scientific descriptions of dinosaur remains, a menagerie of lifelike dinosaur sculptures was unveiled in London 's Crystal Palace Park. The Crystal Palace dinosaurs proved so popular that a strong market in smaller replicas soon developed.
In subsequent decades, dinosaur exhibits opened at parks and museums around the world, ensuring that successive generations would be introduced to the animals in an immersive and exciting way. In the United States, for example, the competition between museums for public attention led directly to the Bone Wars of the s and s, during which a pair of feuding paleontologists made enormous scientific contributions. The popular preoccupation with dinosaurs has ensured their appearance in literature , film , and other media.
Beginning in with a passing mention in Charles Dickens ' Bleak House ,  dinosaurs have been featured in large numbers of fictional works.

The discovery that birds are a type of dinosaur showed that dinosaurs in general are not, in fact, extinct as is commonly stated. National Geographic Readers: Dinosaurs. Using one of the above definitions, dinosaurs can be generally described as archosaurs with hind limbs held erect beneath the body. Temporal range: Late Triassic — Present ,
Jules Verne 's novel Journey to the Center of the Earth , Sir Arthur Conan Doyle 's book The Lost World , the iconic film King Kong , the Godzilla and its many sequels, the best-selling novel Jurassic Park by Michael Crichton and its film adaptation are just a few notable examples of dinosaur appearances in fiction. Authors of general-interest non-fiction works about dinosaurs, including some prominent paleontologists, have often sought to use the animals as a way to educate readers about science in general. Dinosaurs are ubiquitous in advertising ; numerous companies have referenced dinosaurs in printed or televised advertisements, either in order to sell their own products or in order to characterize their rivals as slow-moving, dim-witted, or obsolete.
