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 Egg. The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land. The amniotic egg of reptiles and birds is surrounded by a tough outer shell that protects the egg from predators, pathogens , damage, and drying. Oxygen passes through tiny pores in the shell, so the embryo doesn't suffocate.
