The Ruling Lizards (or Reptiles)

A superorder of reptiles including the crocodilians, the thecodonts (socket toothed), the Pterosaurs (winged lizards), aves (the birds), and the dinosaurs (thunder lizards). All of these but aves and the crocodilians and the are now extinct.

The Archosauria were the dominant form of land life during the Mesozoic period. (And that, my friends, is a long time).
