Dexter is only after the treasures and is killed, but the Eocenes are seeking peaceful co-existence with the humans. Warren agrees to stay so they may exchange cultures and Sarah is given free passage to return home to negotiate their terms.
Sarah is optimistic after speaking with the Brigadier. UNIT this time round seems more sympathetic.
This comic strip story is respectfully dedicated to Malcolm Hulke.
The Silurians are correctly referred to as Eocenes because of the period from which they date.
In the comic strip, K9 relates the earlier attempt by the Doctor to negotiate a peaceful co-existence.
K9 also makes reference to The Daily Telegraph report of 12 April 1929 which tells how an Antarctica expedition was lost following their claim to have found a lost city of intelligent reptiles.
The entrance to the tunnels is rich in hieroglyphics that predate Zoser (2650 BC) yet are more recent. The dig officially reports no findings although Dr. Martyn never returns.
Artist Vincent Danks includes K9 in a couple of fun, tongue-in-cheek visual gags that don't make a great deal of sense. For instance, we see K9 reading the book, The Adventures of Lassie, without particularly indicating how K9 might have turned the pages. Given K9 Mark II's continual insistence that he was not a dog, it is unclear why K9 Mark III would have been particularly interested in a dog story like Lassie. Later, in Egypt, K9 is shown wearing an adventurer's pith helmet.
