ABS can cause a wide variety of birth defects. These deformities can be relatively minor, involving a finger, toe or minor constriction rings (snug bands of the amnion wrapped around a body part). More severe cases may involve multiple body systems. These severe cases are usually fatal.

Did dinosaurs have amniotic eggs?

The reptiles (including dinosaurs and birds) are distinguished from amphibians by their terrestrially adapted egg, which is supported by four extraembryonic membranes: the yolk sac, the amnion, the chorion, and the allantois (Figure 1).
