Zofia Kielan-Jaworowska was a Polish scientist and the first woman to lead a dinosaur excavation expedition. On her explorations of the Gobi Desert, she discovered many famous animals, including Deinocheirus—a dinosaur that, for decades, was known only by its enormous, terrifying arms & claws. But when we finally found the rest of its body, it turned out to look more like Jar Jar Binks. This is the story of Zofia, and the dinosaur that surprised us all - as told originally aired on the History Dispatches podcast with Matt and McKinley Breen.History Dispatches Podcast: https://historydispatches.com/The Explorers Podcast: https://explorerspodcast.com/History Dispatches & Explorers Podcast are part of the Airwave Media Network: www.airwavemedia.comI Know Dino Website: https://iknowdino.comI Know Dino Book: https://books.disney.com/book/i-know-dino/Sources:https://archive.org/details/inpursuitofearly0000kiel/page/n5/mode/2uphttps://archive.org/details/huntingfordinosa00kielhttps://iknowdino.com/deinocheirus-episode-527/https://www.nature.com/articles/520158ahttps://www.nature.com/articles/nature.2014.16203https://www.nature.com/articles/nature13874https://www.nature.com/articles/nature13930See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
