In 1922, the party discovered a fossil of ''[[Indricotherium]]'' (then named "''[[Baluchitherium]]''"), a gigantic hornless [[rhinoceros]], which was sent back to the museum, arriving on December 19. During four expeditions in the [[Gobi Desert]] between 1922 and 1925, he discovered ''[[Protoceratops]]'' (the species ''P. andrewsi'' was named after him), a [[nest]] of ''Protoceratops'' [[Egg (biology)|eggs]] (later studies revealed them to be ''[[Oviraptor]]'' eggs), ''[[Pinacosaurus]]'', ''[[Saurornithoides]]'', ''Oviraptor'' and ''[[Velociraptor]]'', none of which were known before. ''[[Andrewsarchus]]'' was named after him.<eod>

In the 1920s, he went to Mongolia, hoping to find out something about the origins of the human race. He didn't find out anything about early humans, but he discovered a [[treasure]] trove of [[dinosaur]] [[bone]]s.
