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.
