Three Young Fossil Hunters Discover Rare Teenage T. rex in North Dakota

The remarkable find by two brothers and their cousin could reshape our understanding of Tyrannosaurus rex growth and behavior.

The fossil was found in the Hell Creek Formation, a rich paleontological site in North Dakota.
The boys, aged 7 to 10, initially thought they had found a common duckbill dinosaur bone.
Paleontologists identified the fossil as a juvenile T. rex, estimated to be 13 to 15 years old.
This discovery is significant due to the rarity of juvenile dinosaur fossils, which can provide new insights into T. rex development.
The find and its excavation are being documented in a film narrated by Sir Sam Neill, premiering June 21.
