 For example, the feathered dinosaur revolution, facilitated by unprecedented discoveries in the Liaoning province of northern China in the late 1990s and early 2000s, was perhaps foreseen by artist Sarah Landry, who drew the first feathered dinosaur for Bakker's seminal "Scientific American" article in 1975.One of the first major shows of dinosaur art was published in 1986 by Sylvia Czerkas, along with the accompanying volume "Dinosaurs Past and Present".Although various authors are in agreement about the events that caused the beginning of the Dinosaur Renaissance, the transition to the modern age of paleoart has been more gradual, with differing attitudes about what typifies the demarcation.
