Carnivorous Dinosaurs

The dinosaur age spans across roughly 170 million years, and like all dinosaurs, the carnivorous species got bigger as time went on, also growing in intelligence and hunter abilities, most formidably being that of improved senses; sight, hearing, smell and an increased sense for dangers.

To begin the dinosaur timeline there was the Triassic period (46 million years), then there was the Jurassic period (56 million years), and finally the Cretaceous period (80 million years).

Since the discovery of dinosaurs fossils proving life on earth millions of years ago, there have been hundreds of dinosaur species discoveries, and given the toughened protection of large herbivores there is not even a hint of a doubt that the carnivores were fearsomely equipped to take down lethal prey.

These are the teethier of the most dangerous carnivorous dinosaurs that ever lived.

No.1 - Tyrannosaurus-Rex

Larger than most carnivores, the Tyrannosaurus was a devastatingly brutal killer, with a skull that is 5 feet long, a body that is up to 40 feet long, and its height was between 15-20 feet tall. Weighing roughly 8.8 tonnes, the Tyrannosaurus was much more robustly built to tackle larger prey, also making them much more capable in fights with other large predators of the day.

A bite-force twice that of a modern day Great White Shark, and a row of teeth that were big and serrated like knives back to back, the tyrannosaurus could open its jaw much wider than most carnivores of its size, and with the strongest jaw (*bite-force) on earth there really wasn’t anything living on land that it couldn’t kill and devour.

No.2 - Carnotaurus

Not the biggest carnivore in town, but still one of the best carnivorous hunters of its era, having been one of the fastest large dinosaur runners thanks to its well-built tail, but as with many large two-legged carnivores it wasn’t capable of making sharp turns.

It’s skull was roughly a foot-and-a-half long, and measured roughly 24 feet long in length, weighing an estimated 1.35 tonnes, adding to just why this carnivore was able to hunt so efficiently, having been lightweight in build, with a bite force believed to have been twice as strong as the modern day alligator.

Don’t believe everything you see in movies! Walt Disney’s Dinosaurs animated feature film starred a vast array of dinosaur species, perhaps the most popular of which being the movies villains, the carnotaurs, however Disney took a fair few liberties in making them bigger in size than reality would have seen them.

No.3 - Velociraptor

The Velociraptors grew to around 5-6 feet long, and stood approximately 1-1.5 feet tall in height, which shocks a lot of people having most likely watched and believed the Jurassic Park movies, in which the Velociraptors were the star villains.

Jurassic Park actually based their velociraptors from a separate raptor family genus species, Deinonychus, which was 12 feet long and 6 feet tall, weighing around 150 pounds fully grown.

Despite past beliefs, we now have evidence that proves the raptors had feathers, altering the way we see the velociraptor almost entirely. Ground breaking research has shown that where we once believed dinosaurs to have all been cold-blooded reptiles, there may have actually been some, such as the raptors, that were actually warm-blooded like mammals.

No.4 - Spinosaurus

The Spinosaurus was the biggest land predator of the dinosaur era, 59 feet long, weighing approximately 4 tonnes, with its most notable feature being the tall spines on its vertebrae shaped like a sail, with some reaching a height of 6 feet.

Standing 19.7 feet tall, the Spinosaurus is the biggest carnivore to hunt on land, with the larger Spinosaurs believed to have even outmatched the Tyrannosaurus-Rex, as showcased in the blockbuster hit movie, Jurassic Park 3.

The Spinosaurus, despite what the Jurassic Park 3 movie told us, was most likely a watersport hunte, feeding primarily on fish in rivers, streams and lakes. Given the Spinosaurus had long arms, the large sail on its spine was not simply for show, as its combined body shape is believed to have been perfectly adequate for submerging beneath the water, essentially enabling it to swim, very similar to that of a modern day crocodile.

Also a two-legged carnivore, the Spinosaurus could have hunted on land as well as water, but this would have been at times of dire hunger, as it’s skull was shaped very similar to that of a crocodile, meaning it was more optimised for sensing fish in the water. Unlike the Tyrannosaurus, the Spinosaurus was far more intelligent, having evolved into a far more capable hunter of diversity, in that it was able to hunt in and out of water. The Spinosaurus‘s long arms also have extremely long and sharp claws at the end of them, which could have been used to take down larger prey, as these claws were sharp like razor blades, capable of taring flesh from bone.

No.5 - Allosaurus

The Allosaurus was perhaps the Tyrannosaurus (*late Cretaceous) of the late Jurassic period, reaching lengths of up to 12m (or 49 feet), and weighed approximately 2 tonnes, and had dozens of dagger-like serrated teeth.

The Allosaurus was not quite as robust or even robust-looking as the Tyrannosaurus, but in the end, the Allosaurus lived and went extinct millions and millions of years before the Tyrannosaurus ever came into existence.

No.6 - Gigantosaurus

In a 1995 discovery, the Gigantosaurus was believed to have been the biggest dinosaur land predator, with an enermous length of 12.5 metres (or 41 feet), weighing about 8 tonnes, and a height of between 13-20 feet tall, the Gigantosaurus was a fearsome-striking carnivore of the late Cretaceous period.

Using long blade-like serrated teeth, the Gigantosaurus would have been easily capable of taring large chunks of flesh off its prey without much effort, but the only issue with its jaw would have been holding onto large prey before the victim is able to escape from becoming an evening meal.

No.7 - Mapusaurus

The Mapusaurus was yet another giant predator of the early late Cretaceous period, with a length of 13m (or 42 feet), weighing roughly 4.2 tonnes, and a height of up to 13 feet tall.

Using 360 degree vision the Mapusaurus was always on guard for potential predator rival threats, but lacked having a great centre vision, which would have made the Mapusaurus a weakened target for the Tyrannosaurus, but luckily millions of years of evolution stand between the two species in their very existence on earth.

Aside predators, the 360 degree vision was an evolutionary way for the Mapusaurus to track its prey, lie in wait behind a large rock or some form of camouflage, and then attack at the right moment. Large in size, the Mapusaurus had no known enemies, as most other predators roaming the same lands were smaller and less threatening in size.

No.8 - Utahraptor

Averaging lengths of up to and around 7m (or 23 feet), and 1.8m (or 6 feet) in height measuring from the hip, the Utahraptor is the biggest raptor in the family genus pool, and makes the other raptors look like dinner in comparison.

The Utahraptor weighs between 1-2 tonnes, claws on its hind feet were almost a foot long, and the one long, curved, extremely sharpened single claw on either of it‘s two hind feet were used to slash and disembowel their prey. On their hands, the Utahraptor has three distinguishable claws, and the way that the raptor would use these is by latching onto the side of their prey (*possibly whilst the prey is running) to give them enough time to bite down into flesh.

No.9 - Irritator

There is not a whole lot of evidence to suggest that the Irritator was a darkened, fear-provoking creature that wondered the land and lands waters terrorising similar staturd predators, but this is a direct descendant of the biggest land predator that ever existed, the Spinosaurus, so it would be fair to suggest it was cunning in its attack on nearby threats.

Just like the Spinosaur, except much smaller in size, the Irritator has a crocodile-like skull, and its main food source would have been fish. However, it was a two-legged carnivore that had the ability to hunt in both water and on land. Intelligent, long rows of serrated teeth, the Irritator was a fair size and quite capable of taking down mid-sized land herbivores, as well as fending off other similar sized land predators.

No.10 - Saurophaganax

Reaching a length of up to 15m (or 50 feet), the Saurophaganax would have been 5m (or 17ft) tall, and weighed approximately 6 tonnes, making it quite the fearsome land predator during its existence in the late Jurassic period.

The Saurophaganax was larger than most of the other large predators that existed during the late Jurassic period, but relatively leight for its size, the Saurophaganax is believed to have been built for speed and not power, but do not be fooled as the Saurophaganax was more than capable of taking down relatively large herbivores.

Having dozens of long curved serration teeth at the spears meant this dinosaurs bite would pack quite a punch, likely causing maximum damage and pain to its prey. Some Palaeontologists believe the Saurophaganax to be a sub-species of the Allosaurus, two species that are likely to have crossed paths with one another throughout the late Jurassic period.
