Reptiles, the class Reptilian, are an evolutionary grade of animals, comprising today's turtles, crocodilians, snakes, lizards and tuatara, as well as many extinct groups. A reptile is any amniotes a tetrapod whose egg has an additional membrane, originally to allow them to lay eggs on land that is neither a mammal nor a bird.
Advocates of phylogenetic nomenclature regard the traditional category 'Reptilians' to be invalid, because not all descendants of a common ancestor are included.
