Skink. Found amongst rengarenga, Arthropodium bifurcatum.
Moved quickly across the ground, so I only was able to snag a few photos...
Muir Valley Climbing Area in Red River Gorge
Two different specimens in the photos. Saw about 5 total, most were babies. One was missing its tail. Was able to do a decent macro shot using my Canon MP-E.
Skinks are lizards belonging to the family Scincidae. Together with several other lizard families, including Lacertidae (the "true" or wall lizards), they comprise the superfamily or infraorder Scincomorpha. With more than 1500 described species, the Scincidae are the most diverse family of lizards.
