What defines a reptile?

Answer 1

Something that could be pictured as a dinosuar =/

Don't know. Think of it this way: if an animal is placed in front of you, and you have to analyse it to see whether it's a reptile, what would you look for?

Obviously, you'd look for scaly, greenish hues to the skin, bizarre designs and additions to the bodily functions...lots!

Answer 2

A mammal is warm-blooded, feeds its young with milk, has three middle ear bones, has a neocortex region in the brain, has fur, and has one fenestra (hole) below its squamosal and postorbital bones. A reptile is cold-blooded, does not feed its young with milk, has scales rather than fur, has one middle ear bone, lacks a neocortex in the brain, and has either one fenestra above the squamosal and postorbital ridges, has none at all, or has one above and one below.
