For the first time, they find dinosaur footprints with "perfect" skin prints

Paleontologists are used to finding fossils and dinosaur footprints. But this time, a discovery exceeded all expectations. The experts found first impressions with "perfect" skin impressions, in the city of Jinju, South Korea.

According to the researchers, these types of discoveries are very unusual. Remains of soft tissues, such as muscles or skin, are very rare and are not even well preserved.

Martin Lockley, professor of geology at the University of Colorado at Denver, pointed out that these tracks are the "first clues allowing perfect skin impressions to cover the entire surface of each".

In the study, they managed to identify that these remains coincide with the smallest known theropod, the minisauripus. The footprints are nearly three centimeters long and are in very good condition.

Lockey said that these tracks were formed in a very thin layer of mud and that they are only one millimeter thick. Another notable feature is that when the dinosaur walked on this surface, the texture of the skin of the foot he reproduces perfectly, without slipping.

In the report, published in Scientific reports, noted that the pattern of the skin is similar to the examples of carnivorous theropod dinosaur traces, but much larger.
