11-Year-Old Girl Becomes A Sensation After Discovering Something Exceptional At The Tennessee Lake

Iguanodon (1820)

Back in 1820, naturalist Gideon Mantell discovered some bones that belonged to the dinosaur Iguanodon. However, many naturalists like Georges Cuvier and William Buckland didn’t believe in the discovery as they both thought these bones are of a fish or rhinoceros. They weren’t ready to believe some ancient reptiles existed on Earth and refuted the discovery made by Mantell. Later, Richard Owen gave a detailed view on Iguanodon and they identified this dinosaur. Iguanodon became the second dinosaur after Megalosaurus who was given an official genus identification.
