Overview

• 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.
