Zofia Kielan-Jaworowska was born in 1925 in Sokolow Podlaski, Poland. Her university studies began in the rubble of postwar Warsaw, where the university's geology department had been destroyed and lectures were held in a private apartment. She earned a master's degree in zoology and later a doctorate in paleontology at the University of Warsaw, eventually becoming a professor there.[1]
From 1963 to 1971, she led the Polish-Mongolian Palaeontological Expeditions into the Gobi Desert, one of the most productive dinosaur-hunting collaborations of the 20th century. Her teams recovered around 20 dinosaur species, including a six-meter Gallimimus skeleton and the enormous-clawed Deinocheirus, though her own research priority was always the small, easily overlooked early mammals sharing the same Cretaceous landscape -- what she called the "Lilliputians of the Mesozoic world."[2][1]
Kielan-Jaworowska directed the Polish Academy of Sciences' Institute of Paleobiology from 1960 to 1982 and was the first woman to serve on the executive committee of the International Union of Geological Sciences. Her 1969 book Hunting for Dinosaurs, later translated into English, remains a firsthand account of the Gobi expeditions. She died in Warsaw in 2015 at age 89.[1][2]
