Sphenodontidae

provided by wikipedia EN

Sphenodontidae is a family within the reptile group Rhynchocephalia. Most members of this family are only known from fossils but there is one living member, the tuatara (Sphenodon punctatus)[2] from New Zealand. They were a quite ecologically diverse group, ranging from terrestrial carnivores and insectivores (Sphenodon) to aquatic herbivores (Ankylosphenodon) and durophagy (Oenosaurus[3]).

The following is a cladogram of Rhynchocephalia after Rauhut et al. (2012):[3]
