Lizard among these animals best describes a skink. Skinks are lizards belonging to the family Scincidae and the infraorder Scincomorpha. With more than 1,500 described species, the Scincidae are one of the most diverse families of lizards. Most species of skinks have long, tapering tails they can shed if predators grab onto them. Such species generally can regenerate the lost part of a tail, though imperfectly.
Species with stumpy tails have no special regenerative abilities. Skink-like lizards first appear in the fossil record about 140 million years ago, during the early Cretaceous, mostly jawbones that appear very skink-like. Definitively skink fossils appear later, during the Miocene period.
