During a recent 4H trip, 12-year-old Corbin Bullard from Clearwater, Kansas, unearthed an 80-million-year-old marine fossil in Jewell County. Initially discovered in September while he was still 11, Corbin found what appeared to be seven or eight large vertebrae. His fossil, identified as a tylosaurus, a type of mosasaur that lived in the ancient seas of Kansas during the Cretaceous period, measures over 15 feet and is made up of eight pieces. Corbin's passion for dinosaurs fueled his interest in the find, which experts say is related to modern-day snakes and swam using paddle-like flippers. The young paleontologist has spent more than 30 hours cleaning the fossil, and he plans to showcase it at the Sedgwick County Fair from July 8-11. Stephanie Hays, the Sedgwick County 4-H agent, expressed pride in Corbin's dedication and the significance of his discovery.
