!!Tropes:

* AllAnimalsAreDogs: With a Hyaenodon, no less. Innes even ''calls'' it a dog!
** To be fair, David isn't a paleontologist, and just looking at the thing, [[http://www.ljplus.ru/img3/c/r/crazy_zoologist/hyaenodon_pic.jpg it's an easy mistake to make.]]
* BeneathTheEarth
* CanNotSpitItOut
* CanonWelding: The fourth book, ''Tarzan at the Earth's Core,'' quite clearly defines the Tarzan and Pellucidar novels as part of the same continuity, with the usual heroes teaming up with Tarzan and his allies for a {{Crossover}}.
* ContrivedCoincidence
* CultureClash
* DeadpanSnarker: David Innes.
* DistressedDamsel
* DrillTank: The "iron mole".
* DuelToTheDeath: David Innes versus Jubal the Ugly One in ''At The Earth's Core.''
* EverythingsBetterWithDinosaurs
* EverythingsBetterWithPrincesses: Dian the Beautiful.
* EvilAlbino: The Gorbuses are a subterranean race of cannibalistic albinos who are apparently resurrected surface-world murderers.
* EndlessDaytime: As Pellucidar is a HollowWorld that has a sun at the centre, it is always noon no matter where you are.
* FrazettaMan: Sagoths, Ape Men, Beast Men...
* GadgeteerGenius: Abner Perry, inventor of the DrillTank that takes him and David Innes to Pellucidar.
* HollowWorld: The Earth is hollow.
* HypnotizeThePrincess: The Mahars of Pellucidar hypnotize ''everybody''.
* IOweYouMyLife: David Innes saves Ja of the Mezops in ''At The Earth's Core''.
* LiteraryAgentHypothesis
* LostWorld
* MadeASlave: David Innes is enslaved (briefly) by the Sagoths, joining Dian the Beautiful and others who are already in a slave train in ''At The Earth's Core''.
* TheMagnificent:
** Dian the Beautiful.
** Dacor the Strong One, Ghak the Hairy One, Hooja the Sly One, Jubal the Ugly One... etc.
* MightyWhitey: The people from the surface who come to Pellucidar. Something of a variant, as there are other white people in Pellucidar; the surface dwellers are (generally) mighty because of their more technologically advanced culture.
** Except for Tarzan. The Jungle Lord needs no technology to show the cavemen who's boss.
* NubileSavage: Dian the Beautiful. All of her people, too, the Tribe of Amoz. Also their neighbors, the people of Sari.
* {{Pirate}}: The Korsars (corsairs) of Pellucidar.
* ReptilesAreAbhorrent: The Mahars, a race of [[NinjaPirateZombieRobot sentient psychic pterosaurs]], appear as the first major villainous race in the series.
* TravelingAtTheSpeedOfPlot: Some of the stories played with the notion of time as highly variable in a situation where there's no day-night sequence to measure it by. David Innes was once accidentally separated from his comrade and went through several ''weeks'' worth of adventures. When they were reunited, he discovered that since his friend hadn't needed to exert himself to anywhere near the extent David did, for him ''less than an hour had passed''.
