How good they are extinct
When it comes to the most dangerous and terrible animals, which we know, usually fantasy is not started in their ideas further dinosaurs. But in fact, our planet inhabited the beasts, compared to which the tyrantosaurus Rex – just a homely hand kitten. "My Planet" tells about the ten most ferocious and huge monsters that existed on Earth long before us with you.
Paraceratherium (Paraceratherium). The largest of ever existed land mammals
Paracerather, who lived about 30 million years ago, opens our rating of extinct mandes because of their stunning sizes. A 7.5-meter 20-ton creature outwardly was something mean between an elephant and a giraffe and was larger than the largest animal today – the African Elephant – three times. The fact that paraceraserius was herbivore, excludes the possibility of being eaten about them, but this versille could be in two bills.
Meganevra (Meganera). Giant predatory dragonfly
Meganevra – a potential heroine of your terrible dreams. It is considered the biggest known modern science in the insect – the scope of her wings was 65 cm. Meganevra lived 300 million years ago, and for the first time found in 1880, the fossil remains allowed to identify her as a dragonfly. According to the researchers, such impressive insect parameters were due to the special structure of the respiratory system, which scientists claim increased increased oxygen content in the atmosphere of that time (31%), which is 10% higher than today’s level. Humped around a giant dragonfly mainly by other insects. Moreover, the larva Meganevra was also a predator.
Efooberia (Euphoberia). Giant Sorry-skinned
Insectophobians, as, however, and any of us, it is unlikely that I would like to meet with this gigantic waxwork, which lived in the territory of the current Europe and North America in the same period as Meganyevra. Considering that its modern 25-centimeter relatives feed on birds, bats and snakes, it is terribly even to imagine, who would like to breathe their appetites almost a metering efeblery.
Megalania (Megalania). The most huge lizard
Crank, which inhabited the territory of Australia relatively recently (1.6 million – 40,000 years ago). There is a hypothesis, according to which the aborigines, the first to set out the Australian continent, could meet with it. If the assumption is true, then for the ancient Australians, such a meeting did not promise anything good. Megalania, the most huge of the existing lizards, according to the estimates of scientists, reached 7.5 m. The nearest relative of modern Varanov had wide and sharp, as a blade, teeth, which, along with massiveness, made it the main land predator of that period.
Entelodon (Entelodon). Very scary
Entelodon, having dwelling 37.2-16.3 million years ago in Asia, Europe and North America, got into our rating because of his frightening type. As we managed to figure out researchers, outwardly these animals were similar to pigs. The dimensions of the enthelodone are comparable to the hippopotamus (about 2 m in height and 1 ton weight). Fierce predators with almost 20-centimeter fangs did not disdains to eat their relatives, so surely a person would have fallen to taste.
Argentavis (Argentavis). The largest flying bird ever existed on our planet
This is a miracle of nature in Argentina just some 5-8 million years ago. But for modern science still remains a secret, how these birds were generally capable of moving. 70-kilogram Argentavis had a scope of wings up to 7 m, which is twice as much as Albatross, recognized by the largest of the now living birds. Argentavis, grade in the sky, developed speed up to 67 km / h. Having mined the victim, successfully swallowed it entirely. Without rivals, capable of being with him for strength and impressivity, Argentavis, presumably, died at the age of 100.
Titanoboa (Titanoboa). Giant snake
Titanoboa, the remains of which were discovered in Colombia in 2004, was recognized as the most huge and heavy snake from all known. After attaching its possible parameters, scientists were amazed: 14 m in length, 80 cm in width. Titanoboa weighed more than a ton, which is four times the weight of the largest serpent – anacond. Scientists have established that this is a monster who lived about 60 million years ago, most of the time was carried out under water, and such a huge size achieved due to a warmer climate of that time with an average annual temperature of + 30-34 ° C.
Megalodon (Megalodon). PRATERA ACUL
Meghalodon – Another ferocious water predator, who lived 20-5 million years ago. Nickname "big tooth" this ancient ancestor shark got not in vain. His teeth were so strong that the pile of China could open without problems. The owner of 276 teeth located in five rows in a 2-meter jaw, Megalodon could boast a body weight in 35-40 tons. The length of this monster reached 15 m (such a truck with a trailer). That the picture was complete, clarify that the newborn young meghalodon can be compared with the current adult part of the White Shark. By the way, you will probably be interested to look at the fact that now from Meghalodonov left. Some are worn like decorations.
Forada (Phorusrhacidae). The largest non-flying birds
Forakoshos replaced extinct dinosaurs and became leading predators of South America from 60 to 2 million years ago. They are like the largest of lacking birds called TERROR BIRD – literally "terrible bird". And not surprising! These gigantic feathers had a 46-centimeter curved beak, ending with a sharp hook, and could swallow the average size of the dog. Three-meter foreorades in running developed the same speed as a modern cheetah, so you can escape from such "birds" it is hardly possible.
Dinosuchus. Dinosaur Food Crocodile
Dirin – more terrible and massive version of modern crocodiles. Inhabiting the land 80-73 million years ago, Denisuh (from the ancient Greek – "terrible crocodile") is considered the most enormous predator from the chalk period, as well as the largest crocodile of all time. According to today’s crocodile standards, the Day was strikingly large (the length of the body is 9-12 m and the estimated weight of up to 5 tons). Considering the parameters of this ultra-slip, very often his prey became dinosaurs, and their teeth did the Turtle shell easily split.
