 Jim Henson originally got the idea of a live action show featuring  animatronic Dinosaurs after being impressed by the technology his  Creature Shop was developing for the first Teenage Mutant Ninja  Turtles film. When the show went into production the same technology  was then used to create the Dinosaurs, as Jim Henson envisioned.  Many of the Ninja Turtle suit actors even worked as various Dinosaur  suit actors for the series.
