Animals that use amniotic eggs are called amniotes, and they include reptiles, birds and mammals. The mammalian amniotic egg is modified for internal development. The allantois and yolk sac make up the umbilical cord, and the umbilical cord and chorion make up the placenta. There isn't a hard egg shell enclosure.
Amniote embryos, whether laid as eggs or carried by the female, are protected and aided by several extensive membranes. In humans, these membranes include the amniotic sac that surrounds the fetus. These embryonic membranes, and the lack of a larval stage, distinguish amniotes from tetrapod amphibians. The first amniotes, which resembled small lizards, evolved 340 million years ago.
