== Discovery and Naming== In 2005, Edwin Cadena, a doctoral student from North Carolina State University, discovered the holotype specimen in the Cerrejón coal mine. The genus name, meaning "Coal Turtle," is derived from Carbon" Latin for "coal" and "emys" Greek for "freshwater turtle," a reference to the coal mine from which the fossil was extracted. The specific epithet honors Dr. David Cofrin.
