Desert Titan Rewrites Spinosaurus Story: 40-Foot Predator Hunted in Sahara Shallows

Paleontologists describe Spinosaurus mirabilis, a roughly 40-foot carnivorous dinosaur from Niger’s Sahara dating to about 95 million years ago, with a distinctive 20-inch skull crest and a jaw setup optimized for catching fish. Found at the Jenguebi site, about 300–600 miles from the nearest ancient shoreline, the fossils suggest a shallow-water, ambush-hunting lifestyle rather than a fully aquatic marine predator, challenging long-held views of Spinosaurus and implying the genus included both inland waders and possible aquatic specialists. This discovery marks the second species in the Spinosaurus genus and underscores a more versatile, environment-spanning lifestyle for these dinosaurs.

Sahara fossil recasts Spinosaurus as inland ‘hell heron’ rather than coastal hunter

A newly described Spinosaurus species, Spinosaurus mirabilis, from Niger’s central Sahara suggests this giant fish-eater lived inland in a forested, river-influenced habitat about 100–95 million years ago, far from coastlines. The fossil reveals scimitar-shaped crests on its back (sheathed in keratin) likely used for display and interdigitating teeth ideal for catching slippery river fish. This finding points to a new evolutionary phase for Spinosaurus as a shallow-water predator capable of wading in up to two meters of water, broadening our view of its ecology beyond coastal environments and indicating it coexisted with long-necked dinosaurs along rivers.

Inland Sahara Spinosaurus Mirabilis Reveals Unseen Crest and Semi-Aquatic Life

A new Spinosaurus species, Spinosaurus mirabilis, was uncovered in Niger's inland Sahara, notable for a striking skull crest and evidence for a semi-aquatic, fish-eating lifestyle unlike other coast-dwelling relatives. Led by Paul Sereno, researchers even assembled 3D skull models on solar power in the Sahara; the crest may have been keratin-covered for display, suggesting a visual display role akin to modern birds. The study was published in Science.
