pterosaur

Pterosaur, which appeared on the earth in Mesozoic Triassic, was the first flying vertebrate, but some people suspected that it was just an empty name and could only glide in the sky at best. However, the latest research shows that pterodactyl can not only fly like a bird, but also be a flight expert because the developed nerve tissue in the brain processes balance information.

Researchers at Ohio University in the United States reported in the latest issue of Nature that they used computerized tomography technology to construct a three-dimensional image of pterosaur brain based on fossils. The image shows that the cerebellar lobe of pterodactyl is quite developed, and its mass accounts for 7.5% of the brain mass, which is the highest proportion among known vertebrates. In contrast, the cerebellar lobe of birds who are good at flying only accounts for 1% to 2% of their brain mass.

The world's first pterodactyl embryo fossil was recently discovered by paleontologists Dr. Wang Xiaolin and Dr. Zhou Zhonghe in the Jehol biota in western Liaoning, China. In June this year 10, related research papers were published in the most famous academic journal in the world-Nature. Because of this great discovery, Nature also distributed relevant news reports and pictures in the "Today's News" column on the homepage of its website. This important discovery was also reported in the American magazine Science published on June 1 1. Because of the discovery of such an extremely precious fossil, people today have obtained strong evidence that the Mesozoic air overlord pterosaur, which appeared and died out at the same time as dinosaurs, flew into the blue sky about 70 million years earlier than birds, not viviparous, but laid eggs like other reptiles and birds.
