Superorder Lepidosauria
The Lepidosauria (from Greek meaning scaled lizards) are reptiles with overlapping scales. This subclass includes Squamata and Rhynchocephalia. It is a monophyletic group and therefore contains all descendants of a common ancestor.

Order Rhynchocephalia
Rhynchocephalia is an order of lizard-like reptiles that includes only one living species of tuatara, which in turn has two subspecies (Sphenodon punctatus punctatus and Sphenodon punctatus guntheri), which only inhabit parts of New Zealand.


 * Family Sphenodontidae 
 * Genus Sphenodon - tuatara

Order Squamata
Squamata is the largest order of reptiles, comprising lizards, snakes and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,000 species,
