As a small boy, nothing excited Keiron Pim more than a visit to London’s renowned Natural History Museum, where he would gaze up at the Diplodocus skeleton and later depart clutching some little memento: an eraser shaped like Stegosaurus, a lurid poster of a Jurassic scene, or a book crammed with dino-facts. It would have blown his mind to know that he’d one day write a book on dinosaurs. Keiron, married with three daughters, is an award-winning nonfiction author, editor, and writing tutor based in Norfolk, England.

In the 1980s, he adapted the hallmarks of his style—dynamic perspectives, extreme three-dimensionality, and vivid colors—to create an entirely new way to represent dinosaurs. His work would prove to be ahead of its time; in light of the latest science, researchers are now confirming the validity of Fabio’s early drawings. He remains a highly regarded paleoartist today, known for his sharp eye in depicting cutting-edge discoveries.John “Jack” Horner is one of the world’s foremost paleontologists, credited with finding the first dinosaur eggs in the Western Hemisphere, the first evidence of dinosaur colonial nesting, the first evidence of parental care among dinosaurs, and the first dinosaur embryos. He served as the inspiration for paleontologist Dr. Alan Grant in Michael Crichton’s Jurassic Park, and as the technical adviser on all of the Jurassic Park films. Horner is Regents Professor of Paleontology, Emeritus, at Montana State University.
