Answer (1 of 2): Embryos are surrounded by a set of fluid filled membranes called the amnion. They normally weigh 1,320 to 2,200 lbs. Eggs produced by reptiles that have a shell that keeps the eggs from drying out. The evolution of amniotic membranes meant that the embryos of amniotes were provided with their own aquatic environment, which led to less dependence on water for development and thus allowed the amniotes to branch out into drier environments. Reptile parents provide little if any care to their young. In humans and other mammals, the chorion fuses with the lining of the mothers uterus to form an organ called the placenta.

While some sauropsids (turtles and crocodiles) have developed hearts that are almost 4 chambered, they are not the synapsid heart with a physical separation between the ventricles. It would have: required some kind of membrane to hold it together, required the embryos to employ some kind of gas-exchange structure (like the gills of caecilian embryos.). The amniotic egg allowed tetrapods to become completely terrestrial. to survive: the amnion, allantois, yolk sac, and chorion. Amniotic eggs have a membrane called the amnion.

Alina's goal in life is to try as many experiences as possible. The hatchlings from amniotic eggs are more developed than that of amphibians, largely due to the vessels within the yolk sac allowing the transferal of nutrients. We will consider birds as a group distinct from reptiles for the purpose of this discussion with the understanding that this does not completely reflect phylogenetic history and relationships.
