Charles Robert Knight (October 21, 1874 – April 15, 1953) was an American wildlife and paleoartist best known for his detailed paintings of dinosaurs and other prehistoric animals. His works have been reproduced in many books and are currently on display at several major museums in the United States. One of his most famous works is a mural of Tyrannosaurus and Triceratops, which helped establish the two dinosaurs as "mortal enemies" in popular culture. Working at a time when many fossil discoveries were fragmentary and dinosaur anatomy was not well understood, many of his illustrations have later been shown to be incorrect representations. Nevertheless, he has been hailed as "one of the great popularizers of the prehistoric past". Source: Wikipedia (en)
