Spinosaurus mirabilis: New Dinosaur Fossils Discovered in the Sahara Desert
Scientists announced the discovery of a new species of spinosaur dinosaur called Spinosaurus mirabilis from fossils found in the central Sahara Desert of Niger. The discovery was published in 2026 and is considered one of the most important spinosaur discoveries in more than a century.
Age
* Lived about 95 million years ago during the Late Cretaceous Period.
* At that time, the Sahara was not a desert. It contained rivers, wetlands, forests, and abundant wildlife.
Size
* Researchers estimate it may have reached 12–13 meters (40–43 feet) in length.
* It was roughly comparable in size to Tyrannosaurus rex, although exact size estimates remain uncertain because the fossils are incomplete.
Unique Features
The most striking feature was a large scimitar-shaped crest on top of its skull.
Scientists think the crest may have been used for:
* Displaying to potential mates
* Recognizing members of its species
* Intimidating rivals
It also possessed:
* Long, narrow crocodile-like jaws
* Conical teeth designed for gripping slippery prey
* A sail-like structure along its back
Diet
Spinosaurus mirabilis was likely a fish-eating predator.
Evidence suggests it hunted:
* Large fish
* Aquatic animals
* Possibly smaller dinosaurs and other prey when available
Its teeth were adapted for grabbing rather than slicing meat.
Lifestyle
This discovery provides evidence that spinosaur dinosaurs may have been semi-aquatic wading predators rather than fully aquatic swimmers.
Researchers compare its hunting style to that of modern herons:
* Standing in shallow water
* Waiting for prey
* Striking quickly with its jaws
Fossils Found
The expedition recovered:
* Parts of the skull
* Teeth
* Crest bones
* Vertebrae from the neck and back
* Limb bones
* Additional skeletal fragments
These fossils allowed scientists to identify it as a distinct species.
Why the Discovery Matters
1. It is the first widely recognized new Spinosaurus species described in over 100 years.
2. It expands our understanding of giant predatory dinosaurs in Africa.
3. It suggests spinosaur dinosaurs were more diverse than previously thought.
4. It provides new clues about how these animals lived and hunted.
