In the Episode “Scent of Prey” dozens of prehistoric Wild Dogs/Jackals are killed by Spear and Fang In self-Defence when they stalk and try to hunt the pair.
Fang's eggs are captured and held over her and Spear's heads as leverage. They are repeatedly used by Queen Ima to force them both into submission, even after they hatch. This continues through episode 8 and 9.
Queen Ima slashes a blade across Spear's fingers to get hin to drop his weapon. It's brief, he screams in pain and drops his weapon, and goes on fighting like it didn't happen.
Animals are killed out of self-defense or for food.
The episode "A Cold Death" features the repercussions Spear and Fang face from killing a member of a mammoth herd for food. Spear is very gentle with the body, seeming to almost pray over it as it takes its last breath.
The episode "Terror of the Ape-Men" features a graphic "fight" scene between Spear and a hoard of the aforementioned Ape-Men. They are all beaten mercilessly, with guts and bones showing as Spear tears them apart to protect Fang.
Various Animals kill each other out of survival, the closest to what would be considered Animal Abuse is when Spear and Fang are captured by the Ape-men in order to be killed for entertainment (with Fang nearly being beaten to death while fighting one of the Ape-men before spear intervenes).
The second episode "River of Snakes" leaves Fang horrified of anything resembling a snake. In "Rage of the Ape-Men," she panics when she notices a worm in the dirt.
An escaped inmate from an asylum attacks a group of posh scientists(?), killing a few of them and thier butler. He is seen graphically ripping pieces of people off with his teeth and eating them.
Spear is burned by a demonic assailant in his final battle. Him and Fang are shown engulfed in flames, however Fang seems to be fine after the flames die out. Spear lives on for a small while afterwards but succumbs to his full body burns.
In the first episode Spear uses a Rock to brake the bone of one of the Red tyrannosaurs. In the fifth episode Fang has one of her legs broken when she is fighting one of the Ape-Men.
In the episode “Rage of the Ape-men” Spear and Fang are captured by the unprovoked titular Ape-men in order to be forced into a gladiator-style battle where they would have both been killed (which could be considered a type of torture)
In the very first episode, two children are shown to be eaten by carnivorous dinosaurs in silhouette. Later, two baby tyrannosaurs are also eaten, this time in full view.
A few episodes after, we find out that one of the witches lost her young daughter in an accident.
Spear’s Mate (along with their children) is killed by the red tyrannosaurs, The sauropod herd is shown to have nests with eggs and because the entire herd is killed (along with the eggs) it is likely that some of the sauropods were parents to the eggs.
They aren't haunted mansion sort of ghosts, but the images of the main character's wife and two children appear in the sun the morning after they're eaten by dinosaurs.
The first episode has a jumpscare right before the title. A large crocodilian (Sachosuchus) launches out of the water and tries to eat the main character
There is a tense scene in “Scent of Prey” where Fang is resting inside a cave which Spear has blocked with rocks in order to keep out scavengers and she can hear the sounds of the Wild Dogs/jackals trying to get in and she can see their shadows through gaps in the rocks
In the “Covent of the Damned” When the witch looks through Spear and Fang’s memories we see Fang’s babies hatch and Spear’s daughter being born (off-screen)
Multiple episodes end on sad notes (The first episode “Spear and Fang” ends with both the main characters having lost their families which is what brings them together. “A Cold Death” ends with the mammoths mourning their dead herd member and “Plague of Madness” ends with the Infected Sauropod burning to death in lava.
Primal is full of violence and gore. The first episode has several dinosaurs being killed and mutilated, as well as fish blood being used as bait for other predators. The driving motivation for the main character, Spear, is witnessing the death of his wife and two children at the jaws of a dinosaur. The same thing happens to another dinosaur that Spear later allies with.
