A remarkably preserved teenage Tyrannosaurus rex that died around 66.5 million years ago is giving scientists a rare glimpse into what the fearsome predator looked like before reaching adulthood.
The fossil was discovered in North Dakota’s famous Hell Creek Formation by an unlikely team — three children and their father. What they found would eventually become one of the most intriguing young T. rex specimens to attract scientific attention.
The dinosaur was estimated to have been only around six to eight years old, yet it was already roughly 17 feet long. At that age, the young predator may have been experiencing an extraordinary growth spurt, potentially gaining as much as one to three pounds per day.
But its size isn’t what makes the fossil so remarkable.
At the Denver Museum of Nature & Science, the specimen’s skull remains intact and partially articulated, making it unusually easy to identify. Its teeth are also remarkably well preserved, providing researchers with a rare opportunity to study a T. rex during its teenage years.
Even more striking, a fossilized palm frond lies directly on top of the dinosaur’s remains, offering a haunting glimpse of the environment in which the animal was buried.
Scientists hope specimens like this can help fill a major gap in our understanding of T. rex growth.
For decades, paleontologists have known what an adult T. rex looked like.
But this extraordinary fossil could reveal what happened during the transformation from a relatively small youngster into the legendary giant predator.
