RE: For Lizards, Three Eyes Are Better Than Two
Wow, I never knew this! Do you think that some dinosaurs had this parietal eye too?

Good question (I actually had to do a little digging, not much material on the subject)! I don't believe dinosaurs had the eye. Because the parietal eye is present in lizards, frogs and fish, it can be assumed that it evolved very early in fish. However, the eye was lost as reptiles began to diverge, hence why we don't see it in snakes, turtles, etc. I would have to assume that by the time dinosaurs arrived on the scene, they had lost that trait (which would also explain its absence in birds).
I didn't know that either! Very interesting!
