These diverged from the early amniote vertebrates before the reptiles diversified.

The earliest fossils of the two surviving amniote groups, synapsids and sauropsids, date from around 313 Ma.

Most snakes focus by moving the lens back and forth in relation to the retina, while in the other amniote groups, the lens is stretched.

Genome-wide analyses also showed patterns of intragenomic heterogeneity in GC content, similar to those of amniote species that possess isochore structures, but less variable.

One of the greatest evolutionary innovations of the Carboniferous was the amniote egg, which allowed for the further exploitation of the land by certain tetrapods.
From the en.wikipedia.org
The amniote egg allowed these ancestors of all later birds, mammals, and reptiles to reproduce on land by preventing the desiccation, or drying-out, of the embryo inside.
From the en.wikipedia.org
The early synapsid mammalian ancestors, a group which included pelycosaurs such as Dimetrodon, diverged from the amniote line that would lead to reptiles at the end of the Carboniferous period.

- Any member of the Amniota
- The amniotes are a group of tetrapod vertebrates (four-footed animals with backbones or spinal columns) that have a terrestrially adapted egg. They currently include mammals (synapsids), and sauropsids (reptiles and birds), as well as their fossil ancestors. ...
- Higher vertebrate capable of terrestrial reproduction, and having an amnion during its development. Includes reptiles, birds and mammals, which share a common ancestor.
- An animal that produces an embryo within a sac that contains amniotic fluid. Amniotes include turtles, lizards, snakes, tuataras, crocodilians, birds, and mammals.
- Member of a clade of tetrapods that have an amniotic egg containing specialized membranes that protect the embryo, including mammals and birds and other reptiles.
- A tetrapod characterised by the possession of an amniotic egg in the primitive condition. This egg consists of a yolk sac, a central cavity surrounding the embryo filled with amniotic fluid, a moist albumin (protective membrane) and a watertight shell. ...
- An animal whose eggs have waterproof linings; all vertebrates after amphibians have amniotic eggs, allowing them to develop on land.
