Scientists have discovered new facts about dinosaurs and mammals.
Paleontologists from the University of Chicago refutes accepted until recently, the view that the rapid development of mammals began after the extinction of the dinosaurs.
Recent studies of paleontologists from the University of Chicago refutes accepted until recently, the view that the rapid development of mammals began after the extinction of the dinosaurs. New species of ancient mammals began to appear on the planet for 20 million years before the extinction of dinosaurs.
Traditionally it was believed that the dinosaurs during the time of its existence, prevented the development of other types of animals. It confirmed the remains of small animals that lived in that era and were insectivorous. But now found the remains of ancient ungulates the size of a modern pig.
The research was conducted based on the analysis of the molar teeth of ancient animals. The results showed that the contemporaries of ancient dinosaurs teeth were different shapes and sizes. On this basis it was concluded that mammals were different types of food and close to the giant lizards lived a large group of diverse animals. The disappearance of familiar species of food led to the extinction of many animal species, including mammals. The diversity of the world of animals decreased greatly, were able to survive only omnivorous.
Cause changes in mammals, most likely, was the evolution of flowering plants. The appearance of seeds, nuts and fruits contributed to the diversity in the diet of this group of animals
