Scientists discover terrifying new Spinosaurus dubbed the “hell heron”

by

Okay, so this is HUGE news for dinosaur fans like me! Scientists just confirmed a brand new species of Spinosaurus – they’re calling it Spinosaurus mirabilis. They found the fossils way out in the Sahara Desert in Niger, and get this – it’s the first new Spinosaurus species discovered in over a hundred years! Seriously cool.

So, I was reading about this crazy dinosaur discovery! Apparently, a team led by paleontologist Paul Sereno found some remains out in Niger back in 2022. It lived around 95 million years ago, and get this – it was huge! They’re saying it was about 33 to 46 feet long, putting it right up there with T-Rex in terms of size. Pretty wild to think something that big roamed the Earth so long ago!

One of the most distinctive features of S. mirabilis, setting it apart from other spinosaurs, is its large, blade-shaped crest on top of its skull – it stood around 20 inches (50 cm) tall. This crest earned it the nickname “scimitar-crested.” Researchers believe the crest was probably covered in a tough material called keratin and used for showing off, perhaps to attract partners or intimidate competitors.

Spinosaurus described as a “hell heron”

Sereno describes this animal as a “hell heron,” suggesting it likely hunted by waiting in shallow water to ambush prey, rather than actively chasing it in the water. This idea is strengthened by the location of the fossils, which were found far inland in areas that were once ancient rivers and wetlands.

The research also points to a unique jaw and tooth structure. Scientists found teeth that fit together like a zipper, likely used to hold onto slippery fish. This is considered a rare feature among dinosaurs that we’ve discovered so far.

Scientists published their findings in the journal Science on February 19, 2026, as they continue to explore how spinosaurids lived and adapted to the evolving landscapes of North Africa.

Visitors will soon have a chance to see copies of the skull. The University of Chicago announced that casts of the skull and a rebuilt crest will be exhibited at the Chicago Children’s Museum beginning March 1, 2026.
