2. Paleontologists often find bone fossils and occasionally footprints, but soft tissue residues like muscles or skin are very rare and usually poorly preserved. In the past few years, scholars from China, South Korea and the United States have been actively looking for a special kind of footprint-Xiaolong footprint, which is the most compact dinosaur footprint in the world. The common dinosaur footprint is about 20 to 30 centimeters long, but the dragon footprint is only about 2 centimeters. If you don't recognize it in the wild, you may miss it.
Three, there are four exquisite dragon footprints, forming a human footprint that spans 1 100 million years and space. "Little dragon footprints are only found in South Korea and China. This is the unique footprint of Cretaceous in East Asia. This is the tenth fossil spot in the world where the footprint of the little dragon was found. This is the first time that footprints have been found. " Lin Zhongyu told reporters. Paleontologists have never found such a perfect impression of skin before. The average diameter of scales on footprints is less than 0.4 mm, which is different from scales that only appeared on footprints in the past. The footprints of Xiaolong preserved the whole sole skin.
According to current scientific research, there are giant dinosaurs and pocket dinosaurs among ancient creatures.
