A flying dragon lizard avoids danger by opening two large, winglike flaps of skin and gliding from tree to tree. The lizard steers and brakes with its tail. The large flaps are supported by elongated ribs which they can expand and retract. The wings are brightly colored and for this reason they are also called the "butterfly lizard".
casque-head lizard - factzoo.com I wish I could remember the name of the dinosaur this guy is reminding me of...it isn't one of the ones that references are continually made about, so I'm having a hard time. Nonetheless, he is very closely related.
Tuatara - Source: Tad Arensmeier. The tuatara has virtually remained the same for over 140 million years. The tuatara is a reptile, but not in the lizard family, it is part of the family Rhynchocephalia (which translates to Beakheads) which appeared over 220 million years ago. All the Beakheads, besides the tuatara - 2 species, became extinct about 60 million years ago. They are very rare, nocturnal animals. Family: Sphenodontidae
