Marsh 1872 Dinosaur (original) (raw)

Wherein, O. C. Marsh recounts the discovery of the remains of a dinosaur from the chalk of western Kansas. According the Carpenter, et al. (1995), these remains were found by Marsh about four miles east of present day Russell Springs, Kansas, on the north side of the Smoky Hill River. Marsh later (1890) changed the genus name to Claosaurus("broken lizard") when major differences between it and _Hadrosaurus_became apparent. The remains found in Kansas indicated a 12 to 15 foot long animal.

The picture below shows a related species of hadrosaur discovered by O. C. Marsh in Wyoming. Earl Manning notes (pers. comm, May, 2003) that "Hadrosaurus"annectens is now considered to be a primitive hadrosaurine called Edmontosaurus.
