Paleontologists have discovered a new species of Spinosaurus in the Nigerien desert, distinguished by a unique crest on its skull. Named Spinosaurus mirabilis, or “wonderful spine lizard,” this find offers fresh insights into the lives of these giant predators. Remarkably, the fossil was found far inland, challenging previous assumptions that these dinosaurs were strictly coastal dwellers.
Led by Paul Sereno, the team uncovered the remains in ancient river sediments, suggesting the animal lived a semi-aquatic lifestyle similar to a “hell heron.” Its interlocking, crocodile-like teeth indicate it was an adept fisher in the deep waters of ancient river systems. This adaptation allowed it to thrive in environments previously thought unsuitable for such large spinosaurids.
The dinosaur’s scimitar-shaped crest remains a mystery, though scientists speculate it was covered in keratin and possibly used for display. This striking feature, unlike anything seen before, adds a new layer to our understanding of dinosaur evolution. The findings, published in the journal Science, highlight the rich paleontological history hidden beneath the Sahara sands.
