Jack Horner is a severely dyslexic dinosaur paleontologist! He attended the University of Montana for 14 semesters without receiving a degree. He has since received three honorary doctorates and a plethora of awards including a MacArthur Fellowship and the Romer Simpson Medal for lifetime achievement from the Society of Vertebrate Paleontology. Jack was Curator of Paleontology at the Museum of the Rockies, and Regents Professor of Paleontology at Montana State University in Bozeman, Montana, for 34 years. He has more than 300 publications including 9 books. He was the technical advisor for all of the Jurassic Park/Jurassic World movies. He currently teaches at Chapman University in Orange, California, where he lives.

James Gorman is a writer and editor and the author or co-author of seven books, on subjects ranging from dinosaurs to penguins to the oddly humorous aspects of science, medicine and technology. He was on the New York Times staff for 28 years, from 1993-2021, working as an editor, reporter and host of the video series, ScienceTake.

His science reporting and humor writing have been published in many newspapers and magazines, including the New Yorker, the Atlantic, Sports Illustrated, Time, Audubon, and most recently The New York Times and The Washington Post. He has taught science journalism at several universities, including Wesleyan University in 2022 and 2017 (Koeppel Fellow, 2022; Kim-Frank Visiting Wrier in Science Journalism 2017) and Princeton University in 2011 (McGraw Visiting Professor of Writing).

Doug Henderson, combining an interest in landscape and Earth History, returned to a long-put-away interest in drawing when moving to Gardiner, Montana, in 1977. This evolved into something of a career in Paleo-art and illustration. His drawings and paintings over the years have appeared in numerous books and publications, been included in national and international touring exhibits—and disappeared into various corporate studio divisions as preliminary and design work for a few movies and animated features.

The Maia illustrations were one of his first efforts to depict a childhood interest in dinosaurs with some sense of pace and place akin to how nature presents itself, representing Mesozoic flora and fauna in a unified way during a single point and place in time—in this case, the Cretaceous Two Medicine Formation of Montana.
