Cristiano Dal Sasso, paleontologist. He has worked at the Natural History Museum of Milan since 1991 and specializes in the study of Mesozoic reptiles, including dinosaurs. In addition to being a scientist, he has also gained notoriety as a science communicator. He studied the first Italian dinosaur, Scipionyx samniticus (known as Ciro), which hit the cover of Nature in 1998 for the exceptional fossilization of its internal organs, arousing great interest in the media around the world. In 2013 he created an international study group sponsored by National Geographic which then published in Science (2014) and again in Nature (2020) the description of the Spinosaurus and the incredible adaptations to aquatic life of this enormous predatory dinosaur, which turned out to be larger than Tyrannosaurus rex. Cristiano Dal Sasso also described the first Italian sauropod dinosaur (“Tito”) and the first Lombard dinosaur, named Saltriovenator, which represents the oldest and largest carnivorous dinosaur of the Lower Jurassic.
