Dinosaurs evolved from reptiles not the other way around.
The first reptiles where thought to have evolved during the late Carboniferous Period about 320 to 310 million years ago.
Dinosaurs do not appear in the fossil record until the late Jurassic Period about 230 million years ago. They evolved from the reptilian infra class Archosaurs.

What two main types of reptiles existed in the Mesozoic Era?

Are alligators and crocodiles dinosaurs?
No crocodiles are NOT dinosaurs. Dinosaurs and crocodiles are however both archosaurian reptiles. Crocodiles are somtimes refered to as ''living dinosaurs''. This is based on the idea that their anatomy hasn't changed much over millions of years. It does not mean that they are members of the group dinosauria. Modern day birds on the other hand ARE dinosaurs.
Are all dinosaurs reptiles?
All reptiles are diapsids. Mammals (like you and I) are, in contrast, synapsids. So in that respect all reptiles are alike. However, I would not say they were all alike. Snakes are reptiles but lack limbs. Alligators are also reptiles, as are lizards. Tuatara, gavials, amphisbaenids, and tortoises each represent one of the four main modern orders of reptiles. They share some characteristics--just as you and I do, but I would not say they were all alike.

Did underwater dinosaurs evolve into crocodiles?
what an interesting topic! Birds and reptiles are the living descendantsof the dinosaurs that survived the meteorite-triggered mass extinction that killed off most of the species living 66 million years ago. And of all reptiles, crocodiles are the most closely related to birds.
Did birds evolve from lizards?
No, birds didn't evolve from lizards, but they did evolve from dinosaurs, a different group of reptiles. Dinosaurs are different from lizards especially because of their hip structure. Birds descended from a group of dinosaurs known as theropods (bipedal carnivores)
How did birds evolve from reptiles?
But they did. Specifically, birds evolved from a subgroup of dinosaurs (which were reptiles) known as theropods. There is a lot of fossil and anatomical evidence for this.
Did modern reptiles evolve from dinosaurs?
No, although modern reptiles and dinosaurs do share common ancestors that lived in the distant past (likely the Carboniferous epoch). Birds, however, evolved from dinosaurs in the Jurassic epoch.
Why did birds evolve after reptiles?
Because they can generate their own body heat - reptiles cannot and need a warm environment
