New 'Hell Heron' Dinosaur Found After 70-Year Sahara Quest

A decades-old clue in a dusty French journal led scientists to one of the most thrilling dinosaur discoveries in recent history. Deep in Niger's Sahara Desert, researchers unearthed Spinosaurus Mirabilis, a massive fish-eating dinosaur with a stunning scimitar-shaped crest.

The adventure began when University of Chicago paleontologist Paul Sereno read about a single dinosaur tooth found in Niger in the 1960s. No one had returned to that site in over 70 years, but Sereno couldn't shake the mystery.

After a failed 2018 attempt stopped by desert conditions, his team returned in 2019 with drones and GPS. They found the original site but not the major fossils they hoped for.

Then a local Tuareg guide arrived at camp with news of big bones. The team loaded up on just enough gas for two days and drove a day and a half into the desert's most remote region.

"He drives right up to the biggest bone I've ever seen in my life," Sereno told ABC News. They found pieces of jaw and skull, including a strange bone fragment neither researcher could identify.

Back at the lab, Sereno and colleague Daniel Vidal realized they had discovered something extraordinary. The bone was part of a massive head crest, unlike anything seen before.

The team returned in 2022 with 20 researchers and 64 armed guards. On day one, they found another crest piece with more skull attached.

"People were literally crying," Sereno recalled. They had confirmed a new species.

The Bright Side

Spinosaurus Mirabilis was roughly the size of a T-rex and lived 95 million years ago. The carnivore likely sported a large, brightly colored crest covered in keratin and used interlocking teeth to catch slippery fish in shallow waters.

Sereno calls it a "hell heron" that waded on sturdy legs through water up to six feet deep. The discovery also settles ongoing debates about Spinosaurus behavior. Finding these remains hundreds of miles from any ocean proves they weren't ocean divers as some scientists believed.

The team collected 55 tons of specimens during the expedition. Each fossil helps paint a clearer picture of what life looked like in this region when it was a lush river system teeming with large fish.

The discovery proves that some of science's greatest finds still await in Earth's most challenging corners, waiting for determined researchers willing to follow the clues.
