a long time, scientists have had doubts as to what the biggest dinosaur in the world.It was believed that the largest predator - it Titanosaurs.However, with time and occurred discoveries revealed that this is not so.At the moment, the biggest dinosaurs in the world - it diplodokidy.They are pushed to the second position titanosaurs, gigantozavrov and tyrannosaurs that were previously recognized as the largest.
Dinosaurs - a unique creature.Unfortunately, none of them did not survive to the present day.About these amazing animals, we can learn only from the excavations.Translated from the Greek language, the word "dinosaur" means "terrible lizard".But the way it is: if you look closely, the lizard - a small copy of a huge dinosaur.They are similar, and the skeleton, and scaly skin surface and other structural features of the body.At the same time the dinosaurs were really terrible predators enormous size.If today in the world there were such creatures, they would have caused fear and panic among the people.
Researchers concluded that these gigantic animals inhabited the earth 160 million years ago during the Mesozoic era.The extinction of the dinosaurs - is part of the "great extinction" when the world disappeared many different things: flying reptiles, molluscs, marine reptiles and others.
As has been said, everything was phenomenal size of the dinosaurs, which are difficult to imagine modern people, but among them were their champions in size.
first - and largest - a dinosaur in the world, or rather, his remains were found in 1815 in Stounsfilde, in Oxfordshire.According to the scientists found fragments of jaw bone belonged to a vast predatory lizard Sauria.It was announced in 1824 at the conference, which is held the Royal Geological Society, professor of geology at the University of Oxford.
Since 2007, it was thought that the biggest dinosaur in the world - futalognkosaurus (lat. Futalognkosaurus).The remains of this monster have been found after nearly two centuries after the first discovery of a dinosaur, in 2007, in Argentina, in the province of Neuquen.As suggested by paleontologists, it refers to a group of titanosaurs.Presumably, he walked the Earth about 85 million years ago.Its name comes from two words: futa and lognko.In the language of the Indians, who inhabited the territory of Chile and Argentina, it means "giant chief."According to scientists, the giant reaches a length of its size to 34 meters.His weight presumably - about 80 tons.
However, in 2010 the world has been presented a new kind - amphicoelias (lat. Amphicoelias).This species belongs to the family Diplodokidy.According to scientific evidence, to date, it is the largest dinosaur in the world.The findings of this substance have been made in the formation Morrison, on the territory of the Bighorn Basin.Unfortunately, the only result of the finds - a fragment of vertebra - collapsed soon after cleaning procedures and have not kept up to date.Today, from the evidence of his existence is the only drawing.Not surprisingly, the size, and indeed the existence of this creature doubt.
But if you still amphicoelias existed, it is not only the largest dinosaur in the world, and the largest of the known creatures.Its length is about 40-60 meters, and weight - up to 150 tons.From these data, it appears that amphicoelias is twice the length of a blue whale is longer and almost 10 meters futalognkosaurus that before it was the largest dinosaur.
Scientists do not rest on their laurels.To date, we put forward the view that there were more massive dinosaurs.For example, bruhathkayosaurus who lived on Earth during the Cretaceous period.
