Edward Drinker Cope (1840-1897) was a US paleontologist who named over one thousand species of fossil animals (some of these were duplicates), including Dimetrodon. He named the following dinosaurs: Agathaumas (1872), Amphicoelias (1877), Camarasaurus (1877), Coelophysis (1889), Cionodon (1874), Diclonius (1876), Dysganus (1876), Dystrophaeus (1877), Hypsibema (1869), Monoclonius (1876), Paronychodon (1876), Pteropelyx (1889), Tichosteus (1877), and others. He also named the dinosaur families: Camarasauridae (1877), Compsognathidae (1875), Hadrosauridae (1869), Iguanodontidae (1869), and Scelidosauridae (1869). The dinosaur Drinker was named by R. Bakker, P. Galton, Siegwarth & Filla in 1990 as a tribute to Cope.
