Chuck Jennissen is a pediatric emergency medicine physician at the University of Iowa Department of Emergency Medicine and the Stead Family Department of Pediatrics in Iowa City, Iowa. Like a lot of children, he was fascinated by dinosaurs, but actually being able to dig up their bones seemed like a pipe dream while growing up on a dairy farm in Central Minnesota. Picking up granite boulders in the corn fields did not hold the same excitement! As he approaches retirement, Chuck has had the opportunity to fulfill some of his long-held interests in paleontology. He has dug in the Morrison Formation with the Burpee Museum of Rockford, Illinois, at the Burpee-Hanksville quarry in Utah for four seasons. He found and dug up the largest femur that has been identified in the quarry since it was first worked in 2007. Chuck has also participated in digs in the Hell Creek with PaleoAdventures for many years, the Carter County Museum in Ekalaka, Montana, and at several private ranches. This summer, he is planning to dig in Alberta at Dinosaur Provincial Park and with the Museum of the Rockies at Egg Mountain near Choteau, Montana. In September, 2024, he was fortunate to prospect and dig in the Gobi Desert in Mongolia on a trip led by Phil Currie.
