Once the dominant vertebrate animals for over 160 million years, Dinosaurs became extinct by the Cretaceous period. The truth about Dinosaur fossils was obscured for centuries partly by mythology; villagers in central China dug up Dinosaur bones for medicinal purposes, thinking the remains were those of dragons. Europeans thought them to be remains of giants that died in the Great Flood. In 1677 the first Dinosaur to be scientifically described was the Megalosaurus, a genus of large meat-eating theropod Dinosaurs of the Middle Jurassic period. The bone fragment was identified as the lower extremity of the femur of an animal larger than anything alive. By 1854, thirty years after the initial scientific descriptions of prehistoric remains, the Crystal Palace Park in London exhibited a series of sculptures of Dinosaurs and Extinct Mammals created by Benjamin Waterhouse Hawkins. Our Prehistoric legacy manifests in the cultural record since the beginning of tools, art, and mythology.
