Russell J. Hawley attended the University of Colorado in 1985 with the intention of becoming a professional palaeontologist. He took classes in geology, biology, zoology, comparative anatomy, and human anatomy and physiology. Then he took calculus and failed it. He took it again and failed it again. After failing calculus for the third time, he switched his major to fine art. He has not regretted it for a single day.
During the 1990s, Russell spent part of each summer at Como Bluff, Wyoming, participating in dinosaur digs under palaeontologist Dr. Robert T. Bakker... who turned out to be a treasure trove of information about reptiles, fossils, geology, and how to draw dinosaurs more accurately.
Russell's artwork has appeared in America's Smithsonian Anniversary traveling exhibition, games, coffee mugs, Prehistoric Times magazine, Mike Everhart's Oceans of Kansas, and Dr. Dale Russell's Islands in the Cosmos. He also drew quarry maps for Dr. Bakker during his Como Bluff days.
After moving to Wyoming in 1997, Russell began volunteering at the Tate Geological Museum at Casper College. After several months the director realized Russell was not going to leave and started paying him a salary. His current work includes giving tours, writing for the museum newsletter, producing illustrations for museum displays, and writing and illustrating Fossil Critters of Wyoming. His one-man show, A Thousand Unnamed Worlds, ran for two years at the Wyoming State Museum in Cheyenne.
