The Central Asiatic Expeditions took place between 1921 and 1930, and were
led by Roy Chapman Andrews. Walter Granger was chief paleontologist and the
second in command. With a team of up to forty scientists, drivers, and
assistants, they were able to collect a vast multitude of objects for the
American Museum of Natural History and make many groundbreaking discoveries such
as the first dinosaur eggs. They explored throughout the Gobi Desert and
cemented this area as a prime location for paleontological study.
