Top 10 Largest Monsters in the Ancient World

This bear went extinct about 3 million – 11.000 years ago. They are the largest terrestrial carnivorous mammals on earth, living mainly in the North American continent, body weight up to 900kg, standing up to 4.6m tall, they can move at a speed of 50 – 70 km/h facilitates the hunting of prey. The giant short-faced bear belongs to the subfamily Tremarctinae, species of bear found throughout Europe and the Americas. The earliest members of this subfamily were bears of the genus Plionarctos (Plionarctos edensis) that lived in present-day Indiana and Tennessee during the Miocene (Middle Age) Neogene (about 10.000.000 years ago). This genus is considered to be the ancestor of the giant short-faced bear and four-eyed bear (Tremarctos ornatus), and the Florida cave bear (Tremarctos floridanus) today. The exact early history of the giant short-faced bear is not known until now, but they were common on the North American continent 800.000 years ago, during the Kansan glaciation, the Pleistocene. The extinct South American bear genus Arctotherium is considered the closest relative of the giant short-faced bear because of its similar size and relatively short face.

Giant short-faced bear Arctodus simus It first appeared during the Pleistocene in central North America, about 800.000 years ago, extending from present-day Alaska to Mississippi, and it became extinct about 11.600 years ago. Their fossils were first discovered in the Potter Creek Cave, Shasta County, California. This is the largest carnivorous mammal that ever lived in North America. In a recent study, the mass of six specimens found was estimated to be one-third of them weighing about 6 kg, the largest up to 900 kg, the height can reach 957 m. On the walls in the Riverbluff Caves are marks proving their enormous size. Arctodus pristinus (4,6 – 3 million years ago), with two specimens found to be from two bears weighing about 2.2 kg and 500,7 kg. This species is widespread in southern North America from northern Texas to eastern New Jersey, and Aguascalientes (Mexico) today, especially in southwestern Florida, in the Santa Fe River 63,6 in Gilchrist County.

This species is similar to sloths, living on prehistoric ground with a body weight of up to 500kg, this species became extinct under human impact through hunting activities. Kangaroo They were so large, they were almost hippos, feeding mainly during the day, the appearance of which made them one of the largest dominant species of the time. The Gambian marsupial is the largest known wild rat. This rat is nocturnal, can grow up to 92 cm (including tail) and weigh more than 4 kg, equivalent to a domestic cat, whose incisors are nearly 3 cm long. They can reproduce very quickly (about 50 pups/year) and pups can give birth as soon as they are 5 months old. After giving birth, Gambia rats only have to wait 9 months to continue laying. They raise six young children at the same time. This species of mouse is omnivorous, both plants and animals. They can also live 7-8 years. They are distantly related to rats in the UK and are said to be the largest and most ferocious rat in the world.

They are called Hero Rat (HeroRat), rigorously trained to assist in demining, is of great interest in Africa and is likely to be deployed elsewhere. Rats have been used effectively in the Tanzanian and Mozambican militaries, and are being used to search for landmines in these two countries. The US military has become interested in the possibility of using them to detect different types of mines. It can be said that training rats like this, leading the way today is the NGO APOPO in the Kingdom of Belgium. Currently, APOPO is achieving success in several African countries. To maintain conditioned reflexes for Gambia kangaroos, mine detectors and deminers must regularly train their reflexes, training time during the week from Monday to Friday and feeding only foods that are safe to eat. carefully selected.

According to scientists who have found fossils of this animal, they are known as the most terrible rodent, almost the size of a gaur. They lived in lowland rainforests 2 to 4 million years ago. This mouse is 53cm long, weighs up to 1 ton, they are composed of sharp fangs to hunt as well as fight off enemies. Giant rat or giant rat is a term for rats that are very large compared to their own and the term is applied to many different species of rodents. They tend to be native to tropical and subtropical regions. Some have thrived in other climates, including the Coypu and Gambian kangaroos, which have become invasive, even occurring in urban areas. Giant rats have also been depicted in popular fiction, where they are often depicted as monster-like creatures.

The large-sized rats are often referred to by the British press as “giant mouse” (Giant rat) or “super rats” are usually domestic rats (rats, brown rats, black rats, mice) that have become large and appear large due to mutations or for various reasons such as nutrition. more and more now. The term “giant” here does not mean that the rats are too large to imagine, but that they become immune to the poisons used by rat exterminators. The emergence of the giant rat is a natural process, this is reflected in the evolutionary process. When dinosaurs were still alive, there were mammals in the world but they were very small, until the dinosaurs disappeared, the earth began to appear as large rats as cows, now extinct. The worst nightmare is probably seeing scary pictures of oversized rats every few months in the newspapers. In fact, cities are not the place to find the largest rats, the species of giant rats that have been proven to be real include the following species, of which many varieties of giant rats exist today: are now extremely vulnerable when habitats are threatened.

Tyrannosaurus is called Tyrannosaurus, lived on the North American continent, about 67 million years ago. Was the last known dinosaur before going extinct. They are about 12.3m long, 4m high, weigh 6.8 tons and are one of the largest carnivores of all time. It is the only dinosaur known to have a full scientific name, and according to scientists, this predator is one of the most powerful of all land animals. The neck of Tyrannosaurus rex formed a natural S-shaped curve like that of other theropods, but it was short and very muscular to support its large head. The forelimbs have only two clawed fingers, together with a small metacarpal bone indicating a degeneration of a third finger. In contrast, the hind limbs of this species are among the longest in size-to-body proportions. of any theropods. Their tails are heavy and long, sometimes containing more than forty vertebrae, to balance the large head and body. To compensate for their large weight, many bones have evolved to be hollow on the inside, reducing their weight without significantly reducing their strength.

skull Tyrannosaurus rex The largest known is up to 1,52 meters long. A large window in the skull reduces weight and provides more room for muscles to attach, as in all theropods. But in another respect, their skulls are significantly different from those of carnivores that do not belong to the superfamily Tyrannosaurus. The skull is very broad at the back but has a narrow snout, allowing unusually good binocular vision. The bones of the skull are large and the nose and some other bones are fused, preventing movement between them; A large number of bones also have small air holes (containing “honeycombs” of air holes) which may have made their bones more flexible as well as lighter in weight. These enhanced features of the skull are part of the propensity of standard tyrannosaurs toward a powerful bite, easily surpassed by all non-tyrannosaurids. The outer tip of the upper jaw is U-shaped (most non-tyrannosauroid carnivores have a V-shaped upper jaw), increasing the amount of tissue and bone a tyrannosaur can tear with a single bite, although it also increase the tension in the front teeth.

This bird was found in South America about 35 million years ago, which are about the size of a human, they don’t even need ice sheets to survive. Fossils were discovered in Atacama – Peru, they have a height of about 1.5m, in which especially the species called Icadyptes salasi is the most terrifying giant. According to the researchers, the giant penguin fossil found was 1,6 meters tall, weighed 80 kilograms, four times its mass and 4 centimeters taller than modern emperor penguins. Scientists identified the scientific name of this penguin as “crossvallia waiparensis”. This bird specialized in hunting on the coast of New Zealand during the Paleocene period about 40-66 million years ago.

According to Canterbury Museum researcher Vanesa De Pietri, this is 2nd giant penguin fossil of Paleocene found in the aforementioned area. She says the finding supports the scientific community’s hypothesis that penguins were large at an early stage in evolution. Previously, scientists speculated that the complete disappearance of giant penguins was due to the appearance of large carnivorous marine animals such as seals and toothed whales. New Zealand has long been famous for being the site of fossilized giant extinct birds, including ostrich-like birds up to 3,6m tall and eagles with a wingspan of up to 3m. Last week, the Canterbury Museum also announced the discovery of a giant parrot fossil up to 1m tall and existed 19 million years ago.

This bird can’t fly, This is the largest bird that has ever existed, the largest carnivore in South America, existed from about 62 million to 2 million years ago.. They are about 3m tall, with a crooked beak like an eagle, a big head that looks like a horse’s head, using their sharp and sure beak to knock down their prey in an instant. The group of birds Phorusrhacidae is about 3m high, has a crooked beak like an eagle with a head as big as a horse’s head. They use their huge beaks to grab their prey or strike precisely at the vital parts of their prey, making the opponent quickly caught.

The discovery of the new species Llallawavis scagliai helps archaeologists gain a deeper understanding of members of the family of the fearsome prehistoric raptor. More than 90% of the fossilized skeleton of Llallawavis scagliai was discovered in northeastern Argentina in 2010. It is the most complete terror bird specimen ever found. According to scientists, Llallawavis scagliai lived about 3,5 million years ago, near the end of the reign of the terror bird. This raptor stands about 1,2m tall and weighs about 40kg.

Scientists have discovered fossils of giant scorpions hey, they appeared 390 million years ago, 2.5m long. This was considered the top predator of its time, with the size of a large crocodile, their food is usually fish, they even eat each other to survive. Currently, scorpions are extremely powerful with 13 families including 1.750 different species, including extremely dangerous species. They can be as small as 9 mm or as large as 20 cm. Some species of scorpions can live up to 25 years.

Their perfect adaptability allows them to survive almost everywhere in the world (except Antarctica), from hot arid deserts to high humidity tropical jungles. Although, there are many eyes (from 6 to 12 eyes) but their eyesight is not good at all, they are just enough to be able to distinguish light from day and night. In return, their sense of smell is extremely sharp, as well as the ability to sense vibrations around to detect prey or hide from enemies. This creature also has a terrifying ability to starve, if food is scarce, they can live for another year by slowing down their metabolism.

This snake is called Titanoboa discovered in South America, with a body length of up to 15m, weighing up to 2.500 pounds, equivalent to nearly 1.200kg, this is considered the lord of the jungle 60 million years ago. ago. This snake became the largest carnivore on earth after the extinction of the dinosaurs, their huge size was due to the influence of the hot humid tropical climate at that time. Their fossils were discovered in Cerrjon – Colombia, humans seem to have no chance of survival if faced with them. Titanoboa is a genus of snakes that lived between 60 and 58 million years ago, during the Paleocene. The only known species, Titanoboa cerrejonensis, is the largest snake discovered to date. By comparing the size and shape of its fossilized spine with that of modern snakes, the researchers estimated that T. cerrejonensis was about 13 meters long, weighed about 1.135 kilograms, and was about 1 meter wide. m at the thickest point on its body.

Fossils of 28 individuals of T. cerrejonensis was found in coal mines at Cerrejón in northern Colombia in 2009. Prior to this discovery, few Paleocene vertebrate fossils had also been found in tropical environments. ancient South America. This species is related to the South American giant python. The fossils were discovered during the expedition of an international team of scientists led by Jonathan Bloch, a vertebrate paleontologist at the University of Florida, and Carlos Jaramillo, a scientist paleontology from the Smithsonian Tropical Research Institute in Panama. Since snakes are cold-blooded animals, this finding implies that the tropics, where the creature lived, must have been warmer than previously thought, by an average of about 32 °C.

This species is called Megalodon, known for its powerful bite that no other species can match. According to scientists, their bite can crush a car, far surpassing the bite of a great white shark or a tyrannosaur. This species first appeared in the ocean 16 million years ago, 16m long, 50 times heavier than the largest white shark today. Their main food is turtles and giant prehistoric whales. According to records from the Renaissance period, giant triangular fossil teeth are often believed to be petrified tongues, or teeth, of dragons and snakes. In 1667, the Danish naturalist Nicolaus Steno, re-confirmed that these were shark teeth, and drew an illustration of a shark’s head with lots of teeth. He describes this finding in The Head of a Shark Dissected.

Shark continuously produce teeth throughout their life. Depending on what they eat, sharks lose a set of teeth every one to two weeks, up to 40.000 teeth in their lifetime. This means that shark teeth are constantly falling to the ocean floor, increasing the likelihood of them becoming fossilized. The main fossils of C. megalodon are teeth and spine. Like all sharks, the C. megalodon skeleton was composed of cartilage rather than normal bone, which makes the specimens very poorly preserved. Although the oldest traces of megalodon date to the Late Oligocene strata, about 28 million years ago, it is generally thought that the species began to appear during the Middle Miocene, about 15.9 million years ago. Although strata extending beyond the borders of the Tertiary are often absent from megalodon fossils, they have been reported to be present in the later Pleistocene deposits, the extinct C. megalodon at the end of the Pliocene, possibly about 2.6 million years ago

This is the largest species of toad that has ever existed on earth, they were found by scientists in Madagascar, they are about the size of a ball or used to play in the sea, 14cm tall, weighing about 4.5kg. The fossils of this animal were found about 70 million years ago, with extremely strong jaws that allowed them to catch even hatched dinosaurs. In the distant age of the dinosaurs, it seems that all animals have become much larger than our time and frogs are no exception. Paleontologists have discovered a giant frog living on the Cretaceous island of Madagascar. This giant frog has an extremely large mouth, when opened to the maximum, they can swallow dinosaurs, so paleontologists have named it Beelzebufo – giant demon frog, hell frog or toad Devil…

In fact, at the present time, on our earth there is still another extremely large frog species, which is the giant frog. Conraua goliath live in Africa. This giant frog lives in the rainforests of southern Cameroon and northern equatorial Guinea, and can grow to over 30 cm tall and weigh 3 kg. If you straighten the hind legs of a giant African frog its length can reach 1m from head to toe. Although the giant African frog is quite large, if placed in front of a demon frog, they will immediately turn into tiny babies. Devil frogs have a body length of more than 40 cm and a body weight of 4,5 kg. If you straighten the hind legs of a demon frog, their minimum length will be 1,5m. Based on the discovered fossils, paleontologists confirm that this is the largest frog known to mankind so far, not only that, it is also a very aggressive species.
