In 1988 Lessem was a Knight Journalism Fellow at MIT and it was at this time that he developed a special affinity for dinosaurs. He wrote his first book, Kings of Creation, in 1990, and in 1993 launched his company, Exhibitsrex, Inc. His first traveling exhibit in 1993 was designed to correct inaccuracies he had identified in Jurassic Park.

Lessem had served as an advisor for the movie Jurassic Park, but was not happy with most of the existing models of dinosaurs, and decided to build his own. This is done in Zigong, China, which is the site of a great deal of robotic industry. Professional paleontologists oversee production of the models.
