Two young brothers and their cousin were wandering through a fossil-rich stretch of the North Dakota badlands when they made a discovery that left them “completely speechless”: a T. rex bone poking out of the ground.

The trio announced their discovery publicly Monday at a Zoom news conference as workers at the Denver Museum of Nature & Science prepare to begin chipping the fossil out of its rock cast at a special exhibit called Discovering Teen Rex. The exhibit's opening on June 21 will coincide with the debut of the film “T.REX,” about the July 2022 find.

It all started when Kaiden Madsen, then 9, joined his cousins, Liam and Jessin Fisher, then 7 and 10, on a hike through a stretch of land owned by the Bureau of Land Management around Marmarth, North Dakota. Hiking is a favorite pastime of the brothers' father, Sam Fisher.

“You just never know what you are going to find out there. You see all kinds of cool rocks and plants and wildlife,” he said.
