Zofia Kielan-Jaworowska

Zofia Emilia Kielan-Jaworowska (25 April 1925 – 13 March 2015) was a Polish paleobiologist. In the mid-1960s, she led a series of Polish-Mongolian paleontological expeditions to the Gobi Desert. She was the first woman to serve on the executive committee of the International Union of Geological Sciences. The most notable dinosaur species she discovered include: Deinocheirus and Gallimimus while Kielanodon and Zofiabaatar were named in her honour.

In her obituary in Nature, Richard L. Cifelli wrote that "Much of what we know about the origin and early evolution of mammals stems, directly or indirectly, from [her work]".
