Knight's work, found in museums around the United States, helped popularize dinosaurs and influenced generations of paleoartists. His early work showing fighting "Laelaps" (="Dryptosaurus") depicted dinosaurs as much more lively than they would be presented for much of the 20th century. At the same time, improvements in casting allowed dinosaur skeletons to be reproduced and shipped across the world for display in far-flung museums, bringing them to the attention of a wider audience; "Diplodocus" was the first such dinosaur reproduced in this way.
