Cro is an American animated television series produced by the Children's Television Workshop and Film Roman. It debuted on September 18, 1993, as part of the Saturday morning line-up for fall 1993 on ABC.[1] Cro lasted 2 seasons and ran in reruns through summer 1995. The show had an educational theme (this was before federal educational/informational mandates took effect in 1996), introducing basic concepts of physics, mechanical engineering, and technology.

The premise of using woolly mammoths as a teaching tool for the principles of technology was inspired by David Macaulay's The Way Things Work; Macaulay is credited as writer on the show.[2] The series finale, "They Move Mammoths, Don't They?" aired on October 22, 1994. The show was released on video (VHS) in a total of nine volumes.


A scientist named Dr. C and her assistant Mike travel to the Arctic to study artifacts and find a frozen woolly mammoth named Phil. They thaw him out and are surprised to find that he can speak. Whenever a situation in modern times involves physics principles, Phil remembers when a similar event occurred long ago in the prehistoric valley of Woollyville with his fellow mammoths and his Cro-Magnon friend Cro, who lived with a family of Neanderthals. Each episode features Phil narrating how a problem was resolved through simple engineering.

The show's (and lead character's) name is an Occitan word for "cave"; it alludes to Cro-Magnon, the location in France where the earliest anatomically modern humans were first discovered.
