The origin of the reptiles lies about 320–310 million years ago, in the swamps of the late Carboniferous period, when the first reptiles evolved from advanced labyrinthodonts. [2] The oldest known animal that may have been an amniote , a reptile rather than an amphibian , is Casineria [ 3 ] [ 4 ] (though it has also been argued to be a ...
