HarperCollins will publish a new novel [Dragon Teeth] by the late Michael Crichton in May 2017. . . . The manuscript was discovered by Crichton’s wife, Sherri, who, through her company CrichtonSun, has been working on the Michael Crichton Archives. Crichton died in 2008. The book follows the real-life relationship between Edward Drinker Cope and Othniel Charles Marsh, who were competing to uncover fossils in the American West during the late 1800s. HC said Sherri Crichton traced the book’s beginning back to a correspondence her husband had with a paleontologist at the American Museum of Natural History named Edwin H. Colbert.
