Tuataras are said to have "third" or pineal eye, with cornea, retina, lens 
etc., but it is hidden under the skin. It is thought that this is actually 
rudiment of something more developed - perhaps remnant of real third eye. The 
idea of three-eyed monsters seems quite strange and interesting.
BUT I havent found any reliable mention of extinct group of animals having 
three fully functional eyes. Did they exist or not?
