Abstract
It seems that the lizards, amphisbaenians and snakes, which together form the order Squamata, like the Rhynchocephalia, also arose from an eosuchian stock in the Triassic, although lizards did not become common until the Cretaceous and the snakes a little later. The amphisbaenians probably represent a very early separation from the lizards, although they are not known as fossils until the Eocene.
