Paleontology humor

There was a young paleontology exchange student from the orient named Lati Do. On an expedition she encountered a set of fossilized bones which, very peculiarly, were arranged as in the manner of the musical scale. She excitedly asked the renowned paleontologist in charge of the dig, “professor, what type of creature was that?” He replied dispassionately, “why, that’s a Doe Reime fossil, Lati Do.”
