The Flaposaurus is a minor character in The Backyardigans.
In the "Eureka!" episode, scientists Uniqua and Tasha search for a Flaposaurus fossil. They eventually find the remains of one. It is unknown how this particular Flaposaurus specimen behaved when it was alive.
The animal's skeleton is a cream-white color. It resembles a short-necked, four-legged creature with a tail and wings on its back.
The Flaposaurus has appeared in one episode of The Backyardigans: "Eureka!" from season one.
