New Spinosaurus Species Reveals Shallow-Water Hunter in the Sahara

Paleontologists in Niger describe Spinosaurus mirabilis, a new species with a nearly half-meter tall, keratin-covered scimitar-shaped crest found in an inland river system, suggesting the predator waded in shallow waters rather than swam; the discovery challenges the idea of Spinosaurus as primarily aquatic and hints the crest served in social signaling.
