New Dino-era Lizard

I admire artists' impressions of long-extinct species of dinosaur-era reptiles imagined out of unearthed bones. These are Sphenodontines by an anonymous artist. Argentinean paleontologists have announced the discovery of a new species from this family: Priosphenodon minimus, so named because it is only about 20 centimetres long (8 inches to you and me). How do they know that this ancient lizard found in Chubut was adult, not a baby? By the wear on its teeth. CLICK for more information.
