Members of the Reptilia (see reptile), also
known as the sphenodontida or "beak-headed" reptiles, that lived during
the Triassic period, 200 million years
ago. Today, the only surviving genus is the tuatara (of which there are
two species: Sphenodon punctatus and S. guntherii) found
on islands off the coast of New Zealand. Although tuataras resemble lizards
in many resembles, they don't, in fact, belong to any lizard family.
