- This story was recorded on 18 and 20 December 2012, 7 March and 16 April 2013.
- Many plot elements are derived from Arthur Conan Doyle's works.
- Both Laura Lyons and Roger Baskerville are characters from The Hound of the Baskervilles. Just like 'real' Roger Baskerville, Roger Baskerville in The Hound of the Baskervilles is an antagonist.
- Professor Presbury, the leader of expedition, is a character from Conan Doyle's The Adventure of the Creeping Man.
- Conan Doyle says he'd write an adventure story about dinosaurs and a professor. This is a reference to The Lost World, which introduces Professor Challenger. In The Lost World, Professor Challenger encounters Stegosaurus, Allosaurus, and Pterodactyl.
- Jago and Litefoot are fugitives after being accused of the attempted assassination of Queen Victoria two days earlier. (AUDIO: The Trial of George Litefoot)
- Arthur Conan Doyle was introduced to the Doctor while he was studying medicine in the University of Edinburgh under Dr Joseph Bell during the 1880s. (TV: The Moonbase)
- The Doctor allows Jago and Litefoot to use his house 107 Baker Street, in which he had lived from November 1866 to November 1867 during his fifth incarnation. (AUDIO: The Haunting of Thomas Brewster)
- Sgt. Quick would later be able to track Private Willis to Moorsey Manor, where he served as the footman. (AUDIO: Murder at Moorsey Manor)
- The allosaurus' skeleton would be stored in UNIT's Vault by 2014. (AUDIO: The Screaming Skull)
