Titan Attack: Will animals be as large as dinosaurs

Giant animals are already well -known creatures that are found in books or fantastic films. Scientists have answered whether it was really to see mammals the size of a dinosaur. We will probably not see land mammals who could compete with dinosaurs: despite the fact that after the death of dinosaurs, mammals began to increase and fill the niche of giants, they will not be able to become even larger. This is due to the peculiarity of the structure of their body, tell in iflscience.

"During Mesozoic mammals were small," said the Professor of Ecology of the Ecology of the Ohopskaya School of Georgia John Hittlman after conducting research in the size ". As the researcher added, the presence of a large number of different lines of evolution, independent of each other, indicates that giant mammals around the world had the same roles.

One of the greatest mammals was the ancient ancestor of the rhino - paraceraratherium. It weighed from 15 to 20 tons. Nevertheless, his descendants are compared to his dwarfs and cannot be compared to dinosaurs. The fact that mammals cannot reach such majestic size are the result of their biology. According to Felic Smith biologist, mammals regulate their body temperature, so they need ten times more energy than reptile or dinosaurs of the same size.

That is, mammals cannot develop such size because of the inability to provide the body with the required amount of energy. Dinosaurs did not have such a need, so poor energy allowed them to grow. Therefore, we will probably not see giant dogs or cats, but at the same time it protects us from possible problems. But do not forget about lizards that do not regulate their temperature. Earlier, Focus told that the gray wolf Sif was not quite a fiction.
