Doctor Who and the Cave Monsters

In this adaptation, the Silurians were given names like Morka, Okdel and K'to. The novelisation gives extensive background to the reptile culture, including a prologue featuring their hibernation beginning. Large parts of the novelisation are told from the reptiles' point of view and there is an extensive back-story given to several characters including Quinn and Major Baker (for some reason, the character is called Major Barker in the novelisation). The novelisation avoids referring to the reptiles as Silurians (the word turns up as a UNIT password) but identifies the dinosaur in the caves as a tyrannosaurus rex.

The cover blurb includes the hilarious claim that dinosaurs are somehow "mammals"!
