Scientists Find Rare Dinosaur Fossil… in a Drawer Nobody Had Opened for Decades

LONDON — It turns out one of the most important dinosaur discoveries in Antarctica wasn’t buried under miles of ice.

It was buried under paperwork.

Scientists have announced that a rare dinosaur fossil collected during a 1985 expedition to Antarctica spent nearly four decades sitting unnoticed in a museum drawer before someone finally took a closer look. The fossil, a tail bone from a long-necked, plant-eating titanosaur, had originally been cataloged simply as belonging to a “large reptile.”

The fossil was collected by British geologist Mike Thomson while he was mapping rock formations on James Ross Island. Since his primary mission involved studying geology and marine reptiles, the unusual bone was carefully labeled, stored away, and largely forgotten.

For almost 40 years.

Eventually, paleontologist Mark Evans happened to notice the specimen while examining the British Antarctic Survey’s collections. Looking at the oddly shaped bone, he wondered if it might not be a reptile after all.

He was right.

After comparing it with better-known dinosaur fossils, researchers confirmed the bone belonged to a young titanosaur, a long-necked herbivore that lived roughly 69 million years ago, back when Antarctica was covered with forests instead of glaciers. Their findings were recently published in the scientific journal Acta Palaeontologica Polonica.

The dinosaur itself was estimated to be about 23 feet long—small for a titanosaur—and scientists believe it probably died near the coast before its body drifted out to sea, where it eventually became fossilized in marine sediments.

The discovery also carried a bittersweet note. Mike Thomson, the geologist who first collected the bone in 1985, passed away in 2020 and never learned that he had actually found one of Antarctica’s rare dinosaur fossils. His colleagues say he would have been thrilled by the discovery.

As news of the find spread, social media had plenty of fun imagining what else museums might have tucked away.

One commenter joked:

“Somewhere there’s probably a drawer labeled ‘Miscellaneous Rocks’ that’s hiding a Tyrannosaurus.”

Another wrote:

“This is exactly why I never throw anything away.”

And perhaps the best quip of all:

“Imagine being the employee who opens a drawer and accidentally discovers a dinosaur.”

Researchers say the rediscovery highlights the importance of museum collections. Thousands of specimens gathered decades ago continue to yield new discoveries as scientists apply modern technology and fresh eyes to old finds.

Apparently, sometimes the next great scientific breakthrough isn’t waiting to be excavated.

It’s waiting for someone to clean out a drawer.
