David Gillette
David Gillette is an American paleontologist best known for his discovery of the dinosaur Diplodocus hallorum. At the time of its discovery, it was the longest dinosaur known.[1]
Diplodocus hallorum
Gillette found eight huge bones of the Diplodocus in northwestern New Mexico in May 1985. Thinking that this was a dinosaur unknown to science, Gillette began comparing the dinosaur bones he found to those of other dinosaurs. TAfter carefully analyzing the results, he presented the results in a press conference at the New Mexico Museum of Natural History and Science. He gave the new dinosaur the name Seismosaurus halli, or "earth shaker." Seismosaurus was later recognized as a species of Diplodocus, and renamed Diplodocus hallorum.
In 1993, Gillette published his book, Seismosaurus: The Earth Shaker, about the dinosaur he discovered. It was published by Columbia University Press and illustrated by Mark Hallett. The book was re-printed in paperback in 1999.
