Millions of years ago, the earth was not like today, it was ruled by many huge and magnificent creatures. These creatures were not only huge and dangerous who was capable of killing a giant dinosaur. We can talk about the 50 feet long snake or the giant wild monkey or the big crocodile who used to hunt huge dinosaurs by themselves, the human species is very lucky that these dangerous creatures have become extinct today.
Gigantopithecus Yeti, Sasquatch and other mythical ape-like creatures would most likely pale in comparison to the Gigantopithecus. This genus of ape is believed to have existed as recently as one hundred thousand years ago in the area that is now India, China, and Vietnam. It same geographical location and the same time frame as several hominin species. The orangutan is the closest living relative of this creature with several significant differences, particularly when it comes to size. Adult male Gigantopithecus blacky were enormous creatures, especially when compared to humans. They were almost ten feet tall and weighed well-over 1,300 pounds with an arm span that exceeded 11.8 feet. Gigantopithecus blacks were four times heavier than present-day gorillas. Gigantopithecus extinction is believed to have been caused by climate change which turned the plants within its environment from forest to savannah, and the ape didn’t adapt to the new food sources.
Because of its long body and scaly appearance, the Sarcosuchus bore a resemblance to the modern-day crocodile. These included muscular tails, powerful jaws and muscles, sharp teeth and farmer-like plates, known as osteoderms that covered the creature’s body from head to tail. The largest Sarcosuchus specimens were about twice the size of a saltwater crocodile and are believed to have weighed up to ten tons. The skull of a Sarcosuchus imperator, the largest member of the species, was determined to have measured 5 feet in length.
Jaekelopterus This verifying creature was the top laborer of the waters it inhabited. The Jaekelopterus is currently the largest arthropod ever discovered with a total length that exceeds eight feet, making it larger than a fully grown human. Also known as ‘the giant sea scorpion’ this alien-looking creature had a segmented body with multiple specialized limbs, some of which featured spikes. When it extended the chelicerae from its claw-like mouth the Jaekelopterus added 3.3 feet to its overall length. It lived around 390 million years ago and, despite its nickname, it’s believed that the Jaekelopterus preferred freshwater rivers or lakes and most likely never ventured into the ocean.
Many people are terrified of insects and bugs especially of those larger in size. However, none of the creepy-crawlers that are around today can compare to the creatures that lived around 300 million years ago that belonged to that Arthropleura genus. They are the largest known land invertebrates ever discovered. These gigantic millipedes could reach sizes of up to 8 feet in length and were possibly the apex laborers of their environment in the late Carboniferous Period.
Livyatan melvillei Its name was inspired by a biblical foster and by Herman Melville, the author of ‘Moby Dick’, a novel about a giant whale. When considering the etymology of its name, it’s not hard to imagine what Livyatan melvillei might have looked like. It was similar in size to a modern-day sperm whale, measuring up to a staggering 57 feet in length, with an average skull size of 9.8 feet. Livyatan melvillei had massive, robust jaws, which unlike those of sperm whales, where equipped with sets of functioning teeth. This creature’s teeth are actually among the largest ever discovered, measuring over 14inches in length.
Even though Komodo dragons are currently the biggest lizards on the planet, they still pale in comparison to their prehistoric ancestor, the Megalania, considered the largest terrestrial lizards ever discovered. Also known as ‘The Giant Ripper Lizard’ this beast inhabited southern Australia during the Pleistocene. The youngest fossils have been dated to around 50,000 years ago, which would mean that the first aboriginal settlers might have encountered giant ripper lizards. If this is true, they would have stood in front of a monster measuring over 23 feet from head to tail and weighing up to 1,500 pounds.
Today our oceans are home to many fairy creatures, but around 360 million years ago, when the Dunkleosteus swam their waters, the situation was much different. As a hyper carnivorous apex laborer, this creature reigned supreme without facing threats from other animals. One component that added to the sea some reputation of the Dunkleosteus was its sheer size. The Dunkleosteus terrelli, the largest of the species, measured up to 30 feet in length and weighed over a tone. It was a slow but lower full swimmer with a heavy farmer exterior. Instead of teeth, it possessed two pairs of sharp bony plates that formed a structure resembling a beak.
With a massive full that could grow up to 3 feet in length, strong neck muscles, and a large bulky body, the Daeodon was the last and largest of the entelodonts, an instinct family of pig-like omnivores often referred to as ‘fell pigs’ or ‘terminator pigs’. These creatures roamed the Earth approximately 37 million years ago and stood as high as 6.5 feet at the shoulder with slender hooved legs that were built for speed. They had full sets of teeth which included lower full molars, heavy incisors, and large canines.
The feature that makes the Therizinosaurus so fairy is not its massive size of 33 feet in length and up to five tons in weight but the enormous claws on each of the three digits on its front limbs. They are believed to have reached 3.3 feet in length, making them the largest claws of any known animal. The Therizinosaurus is believed to have been bipedal, with a broad body and an elongated neck. Despite the lightening appearance given by its distinctive claws, most scientific evidence suggests that the Therizinosaurus was probably an herbivore.
Once believed to be a species of winged dinosaur, this prehistoric animal was actually closer associated with the large marine lobsters that lived around the same time, during the Cretaceous Period. The Azhdarchid was a species of enormous flying reptiles referred to as Pterosaurs. Its name is derived from the Persian word for ‘dragon’, a fitting comparison, considering the fact that these creatures were as tall as giraffes with wingspans that exceeded 50 feet and weights of over 500 pounds.
