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.]

... on their feet. Their feet aren't completely covered in feathers. Are there even any birds with feathers on their feet?

After the asteroid set half the world on fire, natural selection happened, and all feathered-feet dinos and birds died off while the bare-feet ones survived.
Prove me wrong.
