DinoGuide: Diplodocus carnegii
Diplodocus was one of the longest animals ever to walk the earth.
One of the best
known sauropod dinosaurs, Diplodocus had a more slender body
and longer neck and tail than its close relative Apatosaurus.
The distinctive skull of Diplodocus has the bony nostrils
placed on the top of the head. The peg-like teeth are restricted
to the front of the jaws.
forming most of the reconstructed skeleton on exhibit, CM 84, was
found in 1899 and was vital in establishing Carnegie Museum's place
in the collection and study of dinosaurs. Andrew Carnegie was so
delighted with this find that he presented plaster casts of the
skeleton to major museums around the world. Today, casts of Carnegie
Museum's Diplodocus stand in museums on four continents.
During the first
excavations at what is now Dinosaur National Monument, Carnegie
Museum collectors were puzzled. They had found bones of several
different sauropod dinosaurs, but which skull belonged with the
bones of Diplodocus? Dinosaurs in Their Time presents a lucky find,
shown as originally preserved: the neck vertebrae associated
with the skull, neatly solving the puzzle.
