Jurassic Impact, as with nature, has its fair share of scary moments, especially with the Not Safe for Work ones.
- The signature picture of a dead Allosaurus in the post What if the Dinosaurs Died out Earlier?
is a rather chilling first picture in the project that signifies the Age of Dinosaurs has essentially already come to an end. - The post Odiodonts: The Jaws of Hatred has the first NSFW picture that pulls no punches by showing a baby multiungulate that has gotten disembowled and is in the process of being eaten alive by the titular Odiodon.
- In the A North American Swamp post there is the mildly unsettling picture of a drooling Atroxodon that gives the vibes of a vicious beast. But that in itself is nothing compared to the terrifying picture of a Secutosaurus stalking at night complete with the Glowing Eyes of Doom.
- The Bad Water Trilogy are posts that all feature an anoxic event and while there are gag images to lighten the mood in all of them, the trilogy features a loss of many aquatic creatures with the final third one ending with the extinction of the entire teleost lineage. note .
- The Smallest and Largest Pterosaurs of the Post-Impact Aptian post that has Dolorodraco, a draft horse-sized interemptoran anurognath that looks like the horrifying mix of a dalmatian, vulture, and tyrannosaurus.
- Europe's Island Giant: Struthiotitan is another post that contains the gruesome image of a male of the titular Struthiotitan biting on a younger male competitor's neck then followed by another even more gruesome image of said younger male bleeding out from its neck injuries and foaming at its mouth as it is surrounded by Mustainovenator who just stand around and wait for it to succumb to its fatal injury.
- Childchewer: The Baby-Eating Snail and the Babies The Xystonoglossus, a venomous harpoon-tongued land slug, lives up to its horrific title by preying upon baby pterosaurs after hibernation.
- Laramidia: The Long Continent has Monstrocanitherium, a wolf-like predator the size of a tiger that has a bone-crushing bite like that of a hyena.
- Plants of the Turonian and the Animals who Benefit, Part 2 has Sphaerognathous a small nyctopterid anurognath with both upper and lower teeth like the lower teeth of a cookecutter shark that they use to tear perfectly round chunks of flesh from animals way larger than them.
- Alongside that they are the primary seed disperser of Carnophyta, a carnivorous gnetophyte that uses thorny vines to ensnare any animal that both lacks the agility and size needed to avoid them.
- The titular creature of Hexodon, the Titan of Laramidia is a large elephantine multiungulate that has a rather unsettling appearance and is aggressive to the point of a picture showing it scaring away MONSTROCANITHERIUM, one of the dominant predators of Laramidia, itself!
- The adult male of the titular creature in Atrophiopteryx: Metamorphosis has a rather gruesome looking appearance with its fingerless club-like hands and the blood-like coloration on its neck and wing stubs. If you thought too much into it, it sort-of looks like they commit self-harm frequently.
- The titular creature of Arlekinocornus: The Killer Clown is a large ammonite the size of a car tire and is brightly colored. Not threatening at all, right? WRONG. According to its blurb on the Reddit page:
u/EpicJM: The secret to Arlekinocornus's success as a hunter are tiny, venomous hooks on the undersides of its pair of longest, spaded tentacles. The colorful patterns on its shell are a warning to predatory dryowhales and other animals that may attempt to dine on it, but its venom is also a weapon to be used on prey. One slap from Arlekinocornus's tentacles will kill a fish around the same size in an instant; the ammonite's typical predators are large enough to survive its self-defense, but experience enough sickness and pain to learn their lesson.
- The Wonderful World of Invertebrates has 2 strong examples out of the only 3:
- One is the pictured Stylacothylacus, a deep sea thylacocephalan the size of a typical human head that is bioluminescent in a way that has strong Red and Black and Evil All Over vibes in regards to color scheme except for its one compound glowing green eye that it uses to lure in prey and has spiky limbs that have each pair serve a different purpose in killing prey.
- Another is the aptly-named Mantis Spider, a venomous spider that has a similar niche to a mantis complete with camouflage.
- The titular creature of The Striped Menace: Frendodon post is a cape buffalo-sized entelodont-like carnivorous creature that is intelligent and has a similar bone-crushing bite to Monstrocanitherium. Not helping is the fact that its eyes are shown glowing in the first picture of it.
- The sphaerognathids are at it again in Strange and Wonderful Pterosaurs of the C/S with a picture of a more frightening looking unnamed sphaerognathid next to a gaping bite wound it made on an unknown brutothere with some blood visible and the creature having visible scars to imply this has happened many times before.
- The titular creatures in ''Creatures of the Night: Somaliodon and Saltomamus'. While the former isn't really that scary apart from its Glowing Eyes of Doom, the latter is nightmarish due to two reasons:
- It's an odiodont, notorious for feeding on the young offspring of other animals.
- Its eyes are blood red, and it doesn't help that they glow in the dark.
