WASHINGTON, June 5, 2024 (BSS/AFP) - What did you do for summer vacation?
Three pre-teen dinosaur aficionados have the answer of a lifetime: they
discovered the remains of a rare juvenile Tyrannosaurus rex in the North
Dakota dirt.

Scientists and filmmakers announced Tuesday that brothers Liam and Jessin
Fisher, age seven and 10 at the time of the find, and their nine-year-old
cousin Kaiden Madsen, were walking in the Hell Creek formation of the
Badlands in July 2022 when they found a large fossilized leg bone.

"Dad asked 'What is this?' and Jessin said, 'That's a dinosaur!'" exclaimed
young Liam on a video call with his brother, cousin, father Sam Fisher,
dinosaur experts and reporters.

They snapped a pic and sent it to a family friend, vertebrate paleontologist
Tyler Lyson of the Denver Museum of Nature & Science, according to a
statement.

When Lyson eventually arrived at the site, he brushed off a tooth and quickly
realized the enormity of what the fossil hunters uncovered: an "extremely
rare" juvenile T-Rex specimen that lived 67 million years ago -- and could
offer critical clues about how the king of dinosaurs grew up.

"It still gives me goosebumps," Lyson recalled on the call.

Kaiden's reaction to learning it was a T-Rex? "This is pretty cool, I can't
believe we just found this."

The fossilized bones were excavated, placed in giant plaster jackets and
lifted by Black Hawk helicopter onto a truck. They were taken to the Denver
Museum of Nature & Science, where the public can soon follow progress on the
fossil's preparation in a new discovery lab.

Rather remarkably, the saga is only emerging now, after a documentary crew
and renowned scientists coordinated in secret over nearly two years with top
natural history museums to present the kids' discovery.

Paleontologists estimate the "Teen Rex" weighed about 3,500 pounds (1,630
kilograms), measured 25 feet (7.6 meters) from nose to tail, and stood about
10 feet tall -- some two-thirds the size of a full grown adult. It was
believed to be 13-15 years old when it died.

"It's remarkable to consider how T. rex might have grown from a kitten-sized
hatchling into the 40-foot, 8,000-pound adult predator we are familiar with,"
Thomas Holtz, a vertebrate paleontologist from the University of Maryland and
a renowned T-Rex authority, said in the statement.

A documentary about the discovery debuts June 21 and will roll out to 100
cities in IMAX, 3D and other formats.

"This is the kind of story that documentary filmmakers dream of capturing,"
co-director David Clark said in the statement.

As for the kids, Liam and cousin Kaiden said they'll remain amateur dinosaur
sleuths, combing the Badlands for new discoveries.

But Jessin is looking to become a full-time paleontologist.

"It's been a lifelong dream of mine -- probably because I've seen the
Jurassic Park movie, and finding this" T-Rex fossil, he said.

Meanwhile, Jessin offered sage advice for his fellow youths: "Put down their
electronics and just go out hiking."
