Unlike their amphibian ancestors, reptiles had a hardy skin and could lay amniotic eggs on dry land. This allowed them colonizes some of the roughest habitats on earth, diversifying into a huge number of species, both big and small.
All modern reptiles, including birds, belong within the clade sauropsida, which split from their sister group synapsida (today represented by mammals) some 320 million years ago. There are 23,000 known species of reptiles living today, 11,000 of which are birds. I have already made a similar tribute to birds and so they are not featured in this video as much as lizards, snakes, turtles and crocodiles.
