Dinodocus (meaning "terrible beam") is a genus of sauropod dinosaur, named by Richard Owen in 1884. The name is now usually considered a nomen dubium. The only species, D. mackesoni, a name given to some fossil bones from the Lower Greensand Group (Lower Cretaceous) of Hythe, Kent, England, were formerly placed in the genus Pelorosaurus (Mantell, 1850[1]), but a review by Upchurch et al. (2004) concluded that Dinodocus is a nomen dubium.[2]

Discovery and naming
editThe holotype was discovered in 1840 by Mr H. B. Mackeson. In 1841, Richard Owen noted on the fossils.[3] The holotype, NHMUK 14695, was listed by Owen as "portions of the corocoid, humerus and ulna, iliac, ischial and pubic bones, a large portion of the shaft of a femur, parts of a tibia and fibula, and several metatarsal bones". Owen assigned the specimen to the pliosaur Polyptychodon.[3] In 1850, Gideon Mantell assigned the specimen to Pelorosaurus[1] but Richard Owen placed the fossils in a separate genus, Dinodocus, in 1884. In 1908, Dinodocus was synonymized with Pelorosaurus again, this time by Arthur Smith Woodward.[4] In 2004, Paul Upchurch validated the genus Dinodocus.[2]
