Top 10 Most Extremely Dangerous Dinosaurs

Stegosaurus is undoubtedly one of the most popular types of dinosaur, but they were also one of the most dangerous. Don’t let its herbivorous nature fool you – a Stegosaurus could mess up other dinosaurs like nobody’s business. This guy was extremely large, heavily built, and covered in plates, which made it a physically intimidating foe. However, it’s their tail spikes, known as the thagomizer, which made the Stegosaurus so dangerous. These spikes protruded from the tail and could reach up to three feet in length, and when used with the might of the massive stegosaurus…well, let’s just say that it wouldn’t feel very good to be punctured with it.

The Mapusaurus was the same size as the Giganotosaurus, so you know that the Mapusaurus was one big and nasty dude. A humongous creature, the Mapusaurus measured roughly 33 feet long and weighed 3 metric tons. If that wasn’t all, researchers have theorized that the Mapusaurus hunted in packs, and there’s evidence of these creatures taking down the Argentinosaurus, a massive sauropod measuring 100 feet long and weighing up to 100 metric tons. It seems as if size didn’t matter to the fury that was a hungry pack of Mapusauruses.

Utahraptors were just little guys (well, when compared to other dinosaurs), but like most tiny fighters, they were quick and they were vicious. You certainly wouldn’t want to be in its way when it started swinging. The Utahraptor is estimated to be about 20 feet long and weigh roughly 1,000 pounds, but it’s the dino’s legs which are really worth noting. The Utahraptor had extremely long and dangerous claws which could measure up to 9 inches in length. Yes, combined with the creature’s speed, these deadly claws would prove extremely dangerous indeed.

The massive Carcharodontosaurus fit right in with the likes of some of the biggest dinosaurs in existence, including the Tyrannosaurus and the previously mentioned Giganotosaurus. Scientists claim that the dinosaur could measure up to 44 feet long and weigh up to 15 metric tons, and 8-inch long serrated teeth lined its mouth. To summarize, it was quite a beast. A study done by a man named Donald Henderson even argues that the Carcharodontosaurus could lift dinosaurs weighing up to 935 pounds in its jaws due to its strength and sharp teeth. That thing could kill smaller dinosaurs with a single bite.

Sure, it may have a cute and funny name, but the Majungasaurus was easily one of the most dangerous dinosaurs to have walked the planet. Evidence shows that the Majungasaurus had a similar hunting technique to cats, as they would bite onto a predator and not let go until it bled to death. Teeth marks have been found on the bones of a Rapetosaurus, indicating that the Majungasaurus hunted and killed these elephant-sized creatures with ease. If that wasn’t scary enough, there is also evidence that Majungasauruses were cannibals, as bite marks consistent with the Majungasaurus have been found on bones of the same genus. In short, even Majungasauruses don’t mess with Majungasauruses.

The Spinosaurus certainly sounds like a dangerous creature, and believe us, it more than lives up to its terrifying name. The Spinosaurus was just as large, if not larger, than a Tyrannosaurus, measuring over 45 feet in length and weighing up to 20 metric tons. This makes it one of the biggest, if not THE biggest, carnivorous dinosaurs, and it ate basically anything it could get its claws on. If that wasn’t all, the Spinosaurus also had the ability to swim, so it could take to the water should it not find any fresh meat on land. No one was safe from the fury of the Spinosaurus.

The Ankylosaurus sounds like a complete monster, and we’re sure that its appearance alone scared off more than enough dinosaurs to keep it safe. It weighed 8 metric tons, had four horns on its head, its entire body was protected by armored plates, and various bones in its body were fused together to give it even more strength. On top of its tank-like appearance, it also had a massive clubbed tail, and when swung with enough force, it could easily shatter the leg of an approaching predator or cause some massive damage to its skull. Put simply, dinosaurs wouldn’t want to be anywhere close to the Ankylosaurus when its tail started whippin’.

The Allosaurus is not only one of the most popular and studied genus of dinosaur, but it’s also one of the most vicious. The Allosaurus was an enormous creature, with the largest specimen measuring at over 30 feet long and weighing 2.3 metric tons. Thanks to its size and might, the Allosaurus was king of the food chain, and it preyed on a wide variety of dinosaurs, including sauropods and stegosaurids. It has also been put forth that the Allosaurus hunted in packs, and if that’s true, then that is absolutely terrifying. One is mean enough. We don’t even want to imagine what a group of them could do.

Don’t let the size fool you. While Velociraptors were made famous due to their appearance in “Jurassic Park,” they were actually much smaller in real life – about the size of a turkey. However, they had massive claws that they used for fighting, usually as a means to slit the throat of their victims. Modern research done by Denver Fowler argues that they had another method of killing called “raptor prey restraint.” He thinks the Velociraptor would pin its prey under its massive claws and eat it while it was still alive. Yikes! Velociraptors are violent little guys.

The big daddy himself, nothing beats the Tyrannosaurus. This big guy has been a mainstay in popular culture for some time, typically portrayed as a hulking, carnivorous, violent beast. And, yeah, that’s not too far off. It’s similar in size to a Giganotosaurus, only the T-rex had the strongest bite force of any land-based animal in existence, making it much more powerful. Getting caught between those rows of pointy teeth would not feel great. Sure, its tiny arms may look funny and less-than-intimidating, but its sheer size and strength meant that many other dinosaurs stayed far, far away.
