Which animals have amniotic egg? Timed test, will give brainliest

Amniotes include synapsids (mammals along with their extinct kin) and sauropsids (reptiles and birds), as well as their ancestors, back to amphibians.

Because reptiles, birds, and mammals all have amniotic eggs, they are called amniotes. The duck-billed platypus and some other mammals also lay eggs. But most mammals have evolved amniotic eggs that develop inside the mother's womb, or uterus, and so lack a shell.
