History Literature / OlogySeries

** Phoenixes don't actually die and come back to life as people think, but actually bathe in fire to scorch parasites off of their feathers. At least, this is claimed to be the case in ''Dragonology''; ''Monsterology'' still describes the Phoenix as dying and coming back to life.

* StarfishAliens: Although ''Alienology'' primarily focuses on classic aliens like TheGreys and Martians, there are brief mentions of some weirder intelligent species like Marpeans which look like an orange lump with four hexagons sticking out of them, Gasbags which are giant jellyfish, and Hydeans which look like angels without any limbs.

* FurVersusFang: Vampires have killed werewolves in the past, prompting the lycanthropes to become vampire-hunters in retaliation.

%%* RaptorAttack: Done with mixed success in ''Dinosaurology''.

* DesertedIsland and LostWorld: Yannapalu in ''Dinosaurology''.

* AnachronismStew: Played with in ''Dinosaurology''; the dinosaurs themselves should probably not be coexisting the way they do. However, the book makes sure to avoid having any of the explorers show knowledge of dinosaurs and prehistoric animals that were not recognized by science before the year the book takes place, although the explorers were able to identify ''Velociraptor'' and "''Anatotitan''" (now ''Edmontosaurus'') despite them not being recognized by science at that time. Strangely, the identical ''Deinonychus'' was (properly) described as a creature the likes of which had never been seen before.

* PteroSoarer: Averted in ''Dinosaurology'', as all of the featured pterosaurs are very accurate (the book even shows pterosaurs launching quadrupedally).

* RaptorAttack: Done with mixed success in ''Dinosaurology''.
* RaisedByGrandparents: Standard practice in the culture of the Proboscideans in ''Alienology.''

* ArtisticLicensePaleontology: Justified InUniverse in ''Dinosaurology'', with the inaccuracies that may appear being HandWaved as either the results of editing or perhaps mistakes made by the fictional author. However, it doesn't excuse that amont other things, many of the sauropods have elephantine feet and the raptors are scaley.

* OurManticoresAreSpinier: Lions with human heads, three rows of teeth and scorpion tails that can shoot poisonous, invisible barbs.

* StageMagician: ''Illusionology'' is naturally about these.
* {{Steampunk}}: Some of the books go into it, but ''Illusionology'' (set in 1915) takes the cake, having lots of gear imagery and motifs on it, as well as discussing earky electric technology and robots.

* StageMagician: ''Illusionology'' features these.

* {{Irony}}: Several historical figures throughout history in the series are implied to have been vampires. Despited all his brutality and sheer depravity, Vlad the Impaler was not one of them.

** Phoenixes don't actually die and come back to life as people think, but actually bathe in fire to scorch parasites off of their feathers.

** ''The Dragon’s Eye''

** ''The Dragon’s Apprentice''

* ''Pirateology: A Pirate Hunter’s Companion'' (2006)

* DressedToPlunder: Many of the pirate outfits that ''Pirateology'' displays carry some variations on the classic pirate look. {{Deconstructed}}—Lubber notes that the more extravagant pirate dress makes them easier to recognize as pirates.

* LadyOfAdventure: Lady Hestia in ''Mythology''.

* MagicCarpet: The ''recommended'' method of flight for wizards in ''Wizardology''.

* OurDragonsAreDifferent: ''Dragonology'' makes a point of noting that there are multiple dragon species and each one is different depending on where you go, such as western dragons being the typical medieval winged beasts, eastern dragons being more serpent-esque and intelligent, wyverns being (somewhat unusually) native to Africa and the largest flying dragons in existence, and Australian dragons being almost marsupial in form.
** Even among the various types there are multiple localized subspecies of dragons. Western dragons, for instance, are split between three subspecies -- the typical kind (which in artwork is shown as either the usual quadrupeds or as theropod-like bipeds), the smaller gargouilles, and the arctic dragons, who migrate yearly between the North and South poles and [[AnIcePerson breathe ice]]. Eastern dragons are instead split between the five-toed Chinese ''long'', the four-toed Korean ''yong'', the three-toed Japanese ''ryu'' and the winged Indonesian dragon. Tibetan dragons are a separate, but physically similar, species adapted for mountain life.
** More unusual dragons include the highly theoretical South American amphithere subspecies, which may or may not even exist; pseudodragons such as [[BasiliskAndCockatrice basilisks and cockatrices]]; the three-headed [[OurHydrasAreDifferent hydras]]; the arboreal, koala-like Tasmanian dragons; and the aquatic, finned and ink-spitting Sargasso dragons (although ''Monsterology'' raises the possibility that the latter is not a true dragon).
** Numerous extinct variants are also described, such as the human-headed nagas, a South American species of sparrow-sized dragons that were used by settlers as handheld lighters, the egg-throwing monkey dragons (whose strategy of pelting predators with their rock-hard eggs backfired when used against explorers who were likelier to keep the eggs as curios) and ''Megadracosaurus'', a prehistoric dragon of titanic size.

* WingedHumanoid: The Hadeans in ''Alienology.''

* TreasureMap: Lubber finds one in the beginning of ''Pirateology'', but with a vital piece missing it’s basically useless.

* HeelFaceMole: In ''Pirateology'', the [[spoiler: marooned former member of Drummond’s crew.]]
