Amniotic eggs are the evolutionary separation between amphibians and reptiles. Amphibians lay eggs that must remain moist. Lacking a protected fluid-filled cavity requires the non-amniotic eggs of amphibians to remain in water. With the developmen...
The eggs could also "breathe" and cope with wastes, allowing the eggs and the amniotes themselves to evolve into larger forms. The amniotic egg represents a critical divergence within the vertebrates, one enabling amniotes to reproduce on dry land—free of the need to return to water for reproduction as required of the amphibians.

Amniotic eggs are the evolutionary separation between amphibians and reptiles. Amphibians lay eggs that must remain moist. Lacking a protected fluid-filled cavity requires the non-amniotic eggs of amphibians to remain in water. With the development of the amniotic egg, reptiles were able to lay their eggs on land.
the allantoic sac was dissected away and the amniotic fluid was collected. After the initial collection, fluids (amniotic and allantoic) were collected every other day with 8 eggs collected per species per day. Embryos were classified by stage of development based upon Hamburger and Hamilton (1951). While Hamburger and
