& # 39; Beautifully preserved & # 39; dinosaur SKIN print discovered in South Korean foot tracks made by small raptor as large as a blackbird 120 million years ago
- Researchers identified traces of dinosaur skin in small footprints near Jinju City
- They say it's the first time a skin is found that covers the surface of each song
- Each footprint is only one centimeter long and the scales on the skin are less than 1 mm
In an extremely rare discovery in South Korea, paleontologists have found a series of tiny Cretaceous footprints with well-preserved traces of the skin of a dinosaur.
The prints are made by a mini-genus of meriklank, the smallest known theropod, and each size is only an inch long.
Although less than 1 percent of the numbers still contain traces of the skin, paleontologists say that footprints have been found throughout the Jinju City site.
According to the team, this is the tenth discovery of the traces of Minisauripus and the first contains traces of the skin. The researchers say that the texture of the skin of the dinosaur looks a lot like sandpaper, but with small, half millimeter wide scales that are arranged as a woven fabric (pictured right)
& # 39; These are the first tracks ever found, where perfect skin impressions cover the entire surface of each song & # 39 ;, says Martin Lockley, emeritus professor of geology at the University of Colorado at Denver.
The tracks were first identified by Kyung-Soo Kim, Ph.D., of Chinju National University of Education, and are now the subject of a new article published in the scientific journal Scientific Reports.
According to the team, this is the tenth discovery of the traces of Minisauripus and the first contains traces of the skin.
And they were almost overlooked.
Kim saw the first piece in a broken plate during large-scale excavations and was then able to identify four more.
Although less than 1 percent of the numbers still contain traces of the skin, paleontologists say that footprints have been found throughout the Jinju City site. The numbers are illustrated above
& # 39; The traces are made on a very thin layer of fine mud, instead of a layer of fresh paint that is only a millimeter thick, & # 39; said Lockley.

The analysis suggests that a rain shower occurred just before the tracks were made, creating new impressions of water droplets into which the small dinosaur stepped directly.
After that it was all covered in mud.
The researchers say that the texture of the skin of the dinosaur looks a lot like sandpaper, but with small, half millimeter wide scales that are arranged as a woven fabric.
A similar pattern can be seen in the traces of larger, carnivorous theropods found in other locations, the team notes.
The Miniisauripus skin is essentially a shrunken version of the larger relatives.
& # 39; This is the ultimate secret to skin care & # 39 ;, says Lockley.
WHY DOES THE DINOSAUR EXTINCT GO?
Dinosaurs ruled and dominated the earth about 66 million years ago, before they suddenly died out.
The extinction of the Cretaceous tertiary extinction is the name given to this massive extinction.
For many years it was believed that the changing climate destroyed the food chain of the huge reptiles.
Paleontologists discovered a low iridium in the 1980s.
This is an element that is rare on Earth but is found in large quantities in space.
When this was dated, it exactly coincided with the disappearance of the dinosaurs from the fossil record.
A decade later, scientists discovered the huge Chicxulub crater at the tip of the Yucatán peninsula in Mexico, dating back to the period in question.
Scientific consensus now says that these two factors are interrelated and they were both probably caused by a huge asteroid that crashed to the earth.
With the projected size and impact speed, the collision would have caused a huge shock wave and probably triggered seismic activity.
The precipitation is said to have resulted in plumes of ash that probably covered the entire planet and made it impossible for dinosaurs to survive.
Other animals and plant species had a shorter time span between generations that allowed them to survive.
There are several other theories about the cause of the fall of the famous animals.
An early theory was that small mammals ate dinosaur eggs and another suggests that poisonous angiosperms (flowering plants) eliminate them.
