US paleontologist Paul Sereno poses at the Fossil Lab of the University of Chicago, Illinois, on September 19, 2025 next to the skull cast of the first dinosaur to be named from the Jenguebi fossil area in Niger, the Spinosaurid Spinosaurus Mirabilis. At the end of a true epic across the Niger desert, sparked by a single line in a 70yearold French manuscript, a new dinosaur species has been discovered by an American paleontologist and his team, who published their findings Thursday in the journal Science. No species of this genus had been discovered for more than a century. (Photo by Keith Ladzinski / Fossil Lab, University of Chicago / AFP via Getty Images) / RESTRICTED TO EDITORIAL USE
