In 1993, “Jurassic Park” helped inspire 9-year-old Stephen Brusatte to become a paleontologist. So Dr. Brusatte was thrilled to advise the producers of last year’s “Jurassic World: Dominion” on what scientists had learned about dinosaurs since he was a child. He was especially happy to see one of the most important discoveries make it to the screen: dinosaurs that sported feathers. “A lot of people thought it was made up,” said Dr. Brusatte, a professor at the University of Edinburgh. Now Dr. Brusatte and other paleontologists are trying to determine exactly how feathered dinosaurs achieved powered flight and became the birds that fly overhead today — an evolutionary mystery that stretches more than 150 million years.
