In July 2022, three young brothers, Liam, Jessin, and their cousin Kaiden, discovered a rare juvenile Tyrannosaurus rex fossil while hiking in Badlands National Park, North Dakota.

The fossil was initially mistaken for a duckbill dinosaur but was later identified by paleontologist Dr. Tyler Lyson as a T. rex jaw bone with teeth.

This discovery provides new insights into the growth process of the iconic Tyrannosaurus rex species.

The 3,500-pound T. rex, nicknamed 'Teen Rex,' will be showcased in a temporary exhibition at the Museum of Nature and Science in Denver.

A documentary film about the discovery is set to be released on June 21, highlighting its significance in advancing paleontology and deepening our understanding of dinosaur evolution.
