These were two important scientific expeditions, the first between 1963 and 1965, and the second between 1967 and 1971, both sponsored by the Polish Academy of Sciences and led by the prominent paleobiologist Zofia Kielan-Jaworowska (1925-2015) in collaboration with the naturalist Naydin Dovchin of the Mongolian Academy of Sciences. Her work allowed the discovery of numerous remains of prehistoric animals under the sands of the Gobi desert, among which that of the first Deinocheirus know and a a Protoceratops and a young Velociraptor entangled in a fight, a position in which they were surprisingly fossilized.
