Answer #1

Diapsides include reptiles whose skull was characterized by two temporal fenestrae and would subsequently include all archosaurs as well as lizards and tuataras.

Archosauria is a major group of diapsids  differentiated from the other diapsids by the presence of single openings in each side of the skull, in front of the eyes (antorbital fenestrae), among other characteristics.

Theropoda - Scientists reported the evolution of birds from theropod dinosaurs .The features linking theropod dinosaurs to birds are a furcula (wishbone), air-filled bones, brooding of the eggs, and (in coelurosaurs, at least) feathers.
