Buddy is technically the only main character who is a dinosaur. His adoptive family, Tiny, Shiny, Don and their parents are Pteranodons, a type of flying reptile or pterosaur. Pterosaurs were not dinosaurs but the two groups were closely related and both evolved around the same time.
The fourth season was made using a more low budget style of CGI.
Developed by Jim Henson company
Tomy released a very popular series of toys for the show that where all interactive and would speak and sing with each other by using inferred motion sensors.
The pilot episode shows a very different overall tone to what the show has become. It was originally to contain numerous musical numbers throughout an episode, but now the musical numbers are no more.
