Rhynchocephalia (tuataras)

Wikipedia Abstract

Rhynchocephalia is an order of lizard-like reptiles that includes only one living species, the tuatara (Sphenodon punctatus), which only inhabits parts of New Zealand. Despite its current lack of diversity, the Rhynchocephalia at one time included a wide array of genera in several families, and represents a lineage stretching back to the Mesozoic Era. Many of the niches occupied by lizards today were then held by sphenodontians.
