Paul Sereno and Nizar Ibrahim: helped solve the puzzle of Spinosaurus, the first dinosaur known to swim

2014

German scientist Ernst Stromer unearthed the original bones of Spinosaurus at the turn of the 20th century but they were lost in World War II. The giant dinosaur eluded scientists until 2014, when an international team, including UChicago paleontologists Nizar Ibrahim and Paul Sereno, analyzed newly acquired fossils, remains from museum collections, and historical records to render the dinosaur’s skeleton and reveal it as the first truly semi-aquatic dinosaur.
