Tropes used in Pellucidar include:

• All Animals Are Dogs: 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, it's an easy mistake to make.
• Beneath the Earth
• Cannot Spit It Out
• Canon Welding: 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.
• Contrived Coincidence
• Culture Clash
• Deadpan Snarker: David Innes.
• Damsel in Distress
• Drill Tank: The "iron mole".
• Duel to the Death: David Innes versus Jubal the Ugly One in At The Earth's Core.
• Everything's Better with Dinosaurs
• Everything's Better with Princesses: Dian the Beautiful.
• Evil Albino: The Gorbuses are a subterranean race of cannibalistic albinos who are apparently resurrected surface-world murderers.
• Endless Daytime: As Pellucidar is a Hollow World that has a sun at the centre, it is always noon no matter where you are.
• Frazetta Man: Sagoths, Ape Men, Beast Men...
• Gadgeteer Genius: Abner Perry, inventor of the Drill Tank that takes him and David Innes to Pellucidar.
• Hollow World: The Earth is hollow.
• Hypnotize the Princess: The Mahars of Pellucidar hypnotize everybody.
• I Owe You My Life: David Innes saves Ja of the Mezops in At The Earth's Core.
• Literary Agent Hypothesis
• Lost World
• Made a Slave: 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.
• The Magnificent:
  • Dian the Beautiful.
  • Dacor the Strong One, Ghak the Hairy One, Hooja the Sly One, Jubal the Ugly One... etc.
• Mighty Whitey: 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.
• Nubile Savage: 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.
• Reptiles Are Abhorrent: The Mahars, a race of sentient psychic pterosaurs who appear as the first major villainous race in the series.
• Traveling At the Speed of Plot: 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.
