Summary Introduction
Introduction:
A group of tetrapods collectively known as ‘amniotes’ that includes turtles, lizards, snakes, crocodiles, birds, and mammals. The characteristic feature of amniotes is an amniotic egg. Mammals are considered amniotes because most of them do not lay an egg; they hold other features of amniotic reproduction.
