Inland Sahara Unveils Scimitar-Crest Spinosaurus Mirabilis

Scientists led by Paul Sereno describe Spinosaurus mirabilis, a new inland Sahara spinosaurid from Niger dating to about 95 million years ago. It has a distinctive scimitar-shaped crest and likely hunted fish in shallow water far from the sea, challenging the idea that spinosaurids were coastal. The crest may have been for display; the team used CT scans and 3D models to reconstruct the skull. The discovery suggests an inland habitat and a new evolutionary phase for the group, with fossils set to be displayed in Niamey and the find published in Science.
