This part featured the first appearances of the Autobots Red Alert, Blaster, Grapple, Tracks, Hoist and Smokescreen, and the Decepticons Ramjet, Thrust and Blitzwing. They appear seemingly out of nowhere, though.
Spike borrowed four books about dinosaurs from the library. The covers of two of which are readable: The title of the top book is "Ere Cenozoique Periode Tertiare" - apparently derived from "Ere Cénozoïque (Tertiaire et Quaternaire)", a book by Charles Pomerol, French geologist. The author of the second book is Gideon Mantel, English geologist and paleontologist.
