The Flintstones

The Flintstones was a TV series.

The Tenth Doctor got past a Megalosaurus by jumping onto its head and sliding down the other side, "like he was in the Flintstones title sequence." (PROSE: The Last Dodo)

On The Megalopolis Guide, Catriona told Lief that Baines Molesti's novels about Paynesdown District gave about as much idea about the real place as The Flintstones did about everyday life in a Neolithic flint quarry. (PROSE: Of the City of the Saved...)

Behind the scenes
The Flintstones crossed over with the Doctor Who universe through LEGO Dimensions, where Bedrock appeared as a visitable location.
