Humans have been encountering the fossilized remains of dinosaurs for millennia. The myth of the dragon, for instance, may be based on discoveries of dinosaur fossils. As an example, Chinese historian, Chang Qu mislabeled such a fossil as a dragon in the 4th century B.C.E. The concept of dinosaurs as a group, however, occurred much more recently…in the nineteenth century, in fact. The first published description of what is now known to be a dinosaur bone (but was thought to be the thighbone of a giant human at the time) occurred in the seventeenth century.
