Happy birthday to Zofia Kielan-Jaworowska (1925-2015) a Polish #paleobiologist, famous for a series of Polish-Mongolian expeditions she lead from 1963-1971 to the Gobi desert! 🧪🐡👩🏼‍🔬 #histsci There she discovered dinosaurs including the Deinocheirus, plus she & team found the “Fighting Dinosaurs”
My linocut portrait of Zofia Kielan-Jaworowska shows her as in slacks and sleeveless button down with collar turned in a 3/4 view with her right arm extended and left arm bent and resting on the small of her back. She has short hair and appears brightly lit from the left side. In front of her are the Fighting Dinosaurs fossils: a protoceratops and velociraptor entwined. Above her hand is a Cretaceous rodent Catopsbaatar and behind her is a Deinocheirus dinosaur. She is in the field in Mongolia with mountains in the distance. The print is made in a gradient of sandy golden green through dark green-brown through a dark rust from the bottom to the top.
