History Recap / Primal2019E6PlagueOfMadness

* GrossUpCloseUp: While Spear and Fang sneak past the infected ''Argentinosaurus'', we get to see a close-up of the thing's flesh melting/rotting off its sickly-green sore-covered body, accompanied with disgusting noises.

* Convection Schmonvection: Spear and Fang end up in a volcanic field and are able to navigate it even though the floor itself should've been too hot to even cross. It's only making contact with the lava itself that seems to have any effect.

A ''Camarasaurus'' herd is peacefully grazing on their nesting grounds when one of them gets bitten by a horrifying-looking, zombie-like hadrosaur. Soon, the bitten dinosaur starts showing similar, zombie-like symptoms to the hadrosaur, and eventually turns into a rampaging monster, slaughtering its entire herd and their nests. Spear and Fang chance upon the massacred dinosaurs, and get chased down by the infected monster. They spend the night in a cave hiding from the monster, where Spear has a nightmare of getting infected himself. After the duo leaves the cave, they get attacked again by the monster, who eventually follows them into a volcano and falls into lava from its weight. The episode ends with Spear and Fang somberly watching the creature burning to death.

* EnemyRisingBehind: The plagued ''Camarasaurus'' makes its presence known to Spear and Fang by slowly rising up behind them from a prone position.
* EvilSmellsBad: The scent the plague monster leaves on the dead ''Camarasaurus'' herd members repulses Fang.
* GentleGiantSauropod: Initially played straight with the ''Camarasaurus'' herd peacefully grazing in the valley. Then gets horrifyingly averted by the infected ''Camarasaurus'', who becomes an AxCrazy, destructive monster.
* GrossUpCloseUp: While Spear and Fang sneak past the infected ''Camarasaurus'', we get to see a close-up of the thing's flesh melting/rotting off its sickly-green sore-covered body, accompanied with disgusting noises.
* InstantIllness: It takes a few seconds for the ''Camarasaurus'' to start showing signs of infection after being bitten by the infected hadrosaur.

* StunnedSilence: Fang and Spear don't bat an eye when they see a single dead ''Camarasaurus'' but when they see that the entire herd had been slaughtered yet left uneaten, both are left gazing silently once they see the full extent of the carnage.
* SuperPersistentPredator: The infected ''Camarasaurus'' attacks everything in sight without any self-preservation instinct. It runs into a volcano completely ignoring the lava and even survives being submerged in it the first time.
* TechnicallyLivingZombie: The infected dinosaurs do not actually die from the plague, but they turn into zombie-like monsters with green, rotting flesh and red eyes. In fact, none of the ''Camarasaurus'' that were clearly bitten and killed by the infected one rose back up as zombies, meaning that the plague only affects those that are still alive.

* WouldHurtAChild: The plague monster tramples all the ''Camarasaurus'' eggs, presumably including its very own offspring, and slaughters the juveniles in the herd along with the adults.

* TechnicallyLivingZombie: The infected dinosaurs do not actually die from the plague, but they turn into zombie-like monsters with green, rotting flesh and red eyes.
