History YMMV / Primal2019

** The Night Feeder looks ''disturbingly'' similar to ''Maip macrothorax'', the largest currently known megaraptorid, who was discovered one year prior to the Feeder's episode.

** The Night Feeder bears an ''disturbingly'' similar size and appearance to ''Maip macrothorax'', the currently largest known megaraptorid, who was discovered one year prior to the Feeder's episode.

* AluminiumChristmasTrees: Season 1 episode 3 shows a herd of mammoths mourning the elderly mammoth that Spear and Fang killed. Modern-day elephants are actually known to be one of few species observed in the wild to mourn their dead, to the point they may stay with a dead family member for hours on end.

* EvilIsSexy: Ima is a ruthless, sadistic ruler, but she's also a beautiful woman in a revealing outfit, who at one point performs a seductive dance to tease one of her prisoners. By comparison, the other most prominent female character, the kind-hearted Mira, is relatively more plain-looking (though by no means unattractive) and wears rags for most of her screentime (and even her GoGoEnslavement outfit is less skimpy than the Queen's dress).

** The identities of the two cavemen in the flashback scene in "A Cold Death" are subject to two different interpretations. The more obvious one is that it's Spear teaching his son how to hunt. The other is that Spear is the kid, and the older caveman is his father who has StrongFamilyResemblance. Supporters of the latter idea point to slight design differences: the adult caveman looks slightly hairier than Spear, and the boy looks a bit older than the one who gets killed in "Spear and Fang". The editing does not indicate which interpretation is the correct one. [[spoiler:However, "Echoes of Eternity" shows Spear's father for the first time and makes it clear that they look very different, confirming that the pair in "A Cold Death" really were Spear and his son.]]

* HarsherInHindsight: The episode where the Egyptian Queen dies aired on the same day the Queen of England passed away.

* SpiritualAdaptation: Being a story set in an alternate world were cavemen, [[spoiler: vikings]], and even [[spoiler:victorian gentleman]] appear alongside dinosaurs, Primal is the closest thing to an adaptation of the RTS game VideoGame/{{Paraworld}} we've ever seen.

* NauseaFuel: Some of the symptoms of the eponymous plague in "Plague of Madness" are as disgusting as they are horrifying. These include flesh rotting green and dripping off the bones, pulsating pustules, and extensive vomiting of blood. Even worse, we're treated to a [[GrossUpCloseUp close-up of its flesh]] when Spear and Fang sneak past the infected sauropod while it's dormant.

* SugarWiki/AwesomeArt: Second only to ''WesternAnimation/SamuraiJack'', this is Genndy Tartakovsky's best-looking show, with a visceral, "pulpy" aesthetic, some incredible character designs (some courtesy of ''WesternAnimation/RenAndStimpy'' co-creator Bob Camp) and incredibly fluid animation.

* OneSceneWonder: Some of the creatures with cool and interesting designs have only very short screentime, after which they disappear from the show altogether. Prime examples are the ''[[NeverSmileAtACrocodile Deinosuchus]]'' and the [[PteroSoarer pterosaur]], who both appear in the first episode ''before'' the tragedy that kicks off the plot and the saber-toothed wolves from the third episode.

** [[spoiler:After Ima spent nearly three episodes forcing Spear, Fang, and Kamau to be her glorified living WMDs, and ''especially'' after she forced Kamau to slaughter a surrendering village, audiences were quite happy when Kamau finally mustered the courage to rebel against her and toss her overboard to her death.]]

* CompleteMonster:

** Watch how Red and Fang interact with one another. Fang immediately takes the lead, Red is ready to cede his territory to her without a fight, she chooses to accept him into what is now her territory. Afterwards, she takes the lead for the most part [[spoiler:until he attacks the Celtic village.]] This is classic behavior for ''modern'' raptors, the birds of prey: They are matriarchal and females take the lead in most things. And what are modern birds of prey? Evolved theropods.

** In "Plague Of Madness", the infected ''Argentinosaurus'' starts banging its head against the chasm walls after getting temporarily stuck. Is it doing this because it's a mindless creature letting out a rage because its predicament stops it from pursuing Spear and Fang? Or is it because it managed to gain a semblance of control and tried to kill itself to end its misery?

** The infected ''Argentinosaurus'' from "Plague Of Madness". The poor thing wasn't even malicious to begin with; it was just a peaceful herbivore who got bitten by an infected dinosaur and turned into an AxCrazy monster as a result. Unlike the viewer, Spear doesn't get to see it living peacefully among its herd, but still comes to the same conclusion nonetheless and looks genuinely saddened by the monster's death. The somber music that plays as it the lava flames char it out of its misery only makes it more pitiable.

* TooCoolToLive: [[spoiler:Spear dies in his FinalBattle against the empowered Chieftain, but doesn't go down defeated.]]

** Being a story about a MamaBear T.Rex on a RoaringRampageOfRevenge in a OneMillionBC setting, Primal also makes for a decent adaptation of the 1999 Arcade Game ''Savage Quest''

** Once the Chieftain [[spoiler:manages to fatally would Spear, the devil-like entity he made a deal with then proceeds to have him DraggedOffToHell. Was this because the Chieftain completed his duty in killing Spear and therefore fulfilled his end of the bargain, or was the entity pulling a YouHaveFailedMe on the Chieftain for letting himself be defeated by Spear or failing to kill Fang? Fans have taken different sides on this matter.]]
