In early 2008, after the successful first run of Hey Arnold! on Nickelodeon, Craig Bartlett decided to create another children series, this one set during the era of the dinosaurs, including the Triassic, Jurassic, and Cretaceous periods. Bartlett conceived the idea for the show, drew the main characters, and wrote a pilot script. Bartlett said he got the idea of the show after he saw one of his kids put a toy dinosaur in a toy train.[8]
