Paleontologists are used to finding dinosaur bones and tracks. But remnants of soft tissue, like muscles or skin, are rare and often not well preserved. A very small percentage of tracks – much less than 1% – show skin traces [i.e. impressions].

Kyung-Soo Kim, Ph.D., of Chinju National University of Education recently found a set of very small tracks with perfect skin traces near Jinju City, Korea. CU Denver Professor Emeritus of Geology Martin Lockley, Ph.D., – with Kim, Jong Deock Lim of Korea and Lida Xing of Beijing – wrote a paper about the skin traces for the journal Scientific Reports. They described the skin as "exquisitely preserved."

"The skin traces come from tracks of the smallest known theropod, the Minisauripus."

[Editorial update - clarifying that "skin traces" means "impressions of skin", rather than "traces of skin" - thanks to poster below. --FP.]
