This graphite pencil drawing shows Carpolestes simpsoni

June 2, 2010
This graphite pencil drawing shows Carpolestes simpsoni, an early primate from the Paleocene era. The animal was reconstructed using a skeleton recovered from a 56 million-year-old limestone nodule found in the state of Wyoming. It accurately represents in every visible respect, the animal's known proportions and morphology--from the teeth to the skull to the skeleton. Locomotion on small diameter supports (depicted here) is concluded from the specialized grasping hands and feet; strong, mobile elbow; robust fibula; mobile ankle joints, mobile vertebral column; and gracefully slender pelvis and specialized teeth of the animal.
