Dead dinosaurs, mammals

The size of mammals has increased 1,000 times after the dinosaurs became extinct on Earth, according to a study by scientists at the University of Calgary (Canada).

The two largest terrestrial mammals that once appeared on Earth, Indricotherium and Deinotherium, have a height far beyond that of existing African elephants. ( Photo: Internet).

According to the Daily Mail , scientists have been studying fossils of mammals around the world, including: odd animals such as rhinos and horses; elephants such as elephants, mammoths, mastodons and other mammals.

The results show that, after the extinction of dinosaurs 65 million years ago, the ecosystem has changed completely, making the lives of mammals change. Within the next 25 million years, mammals have evolved very rapidly in the size of the body.

When dinosaurs exist on Earth, the maximum weight of mammals does not exceed 10 kg. However, after the dinosaurs became extinct, mammals evolved very quickly in weight, some species could reach a maximum weight of 17 tons.

'When dinosaurs become extinct on Earth, a large amount of plant food will be devoted to herbivorous mammals. This makes the herbivorous mammals have enough nutrients and evolve very quickly in terms of weight , 'said Dr. Jessica Theodor , head of the study.

Scientists at the University of Calgary have also found that mammals that live in cold climates grow weight faster than their body size, their ability to regulate their bodies. The better the heat.

The results of the study are published in the journal Science on November 26.
