24a. Diplodocus, the Human Dimension, 1899
This partial skeleton of Diplodocus was found by Barnum Brown at Como Bluffs, Wyoming, in 1897, and later excavated by J. L. Wortman and mounted in the American Museum of Natural History in New York. The pencil restoration is unusual for the time in that it includes a human figure to provide scale. Osborn would later use a human to similar effect in the famous restoration of Tyrannosaurus in 1905 [this should link to osb1905.htm], although there the human is more fittingly shown as a skeleton.
