Word History

Etymology

borrowed from New Latin, genus name, from diplo- diplo- + Greek dokós "beam, especially one supporting a roof or floor, bar" (perhaps, if original sense was "something receiving/accepting a load," nominal agentive derivative from déchesthai, dékesthai "to receive, welcome, accept," going back to an Indo-European verbal base *deḱ- "take up, accept, perceive"); so named from the double chevron bones forming part of the caudal vertebrae — more at decent

Note: The genus name was introduced by the American paleontologist Othniel Charles Marsh (1831-99) in "Principal Characters of American Jurassic Dinosaurs. Part I," American Journal of Science and Arts, 3rd series, vol. 16, no. 95 (November, 1878), pp. 411-416. According to Marsh (p. 414), "It [Diplodocus] may be distinguished from the genera already known by the caudal vertebrae, which are elongated, deeply excavated below, and have double chevrons, with both anterior and posterior rami …To the last character, the generic name refers."
