Glyptops plicatulus is a species of turtle from the quarry at Dinosaur National Monument. Two specimens were excavated from the Carnegie Quarry by Earl Douglass in 1913 and described as a new species Glyptops utahensis. This species was later determined to be invalid because Gilmore’s diagnostic feature was the shape of the shell, which was not a distinctive feature since turtle shells are often misshapen due to deformation (Gaffney, 1979).During the removal of overburden in the temporary quarry shelter, a juvenile specimen was collected by Ted White (White, 1955).
