Neoreptiliomorpha

Neoreptiliomorphs are a clade of ectothermic amphibians within the superclass Tetrapoda. This clade comprises the amphibiosaurs (Amphibiasaura), crocophibians (Batrachosuchia), web-wings (Pteramphibia), and the hornfrogs (Ceratorana). Most neoreptiliomorphs lay their eggs on land, while fully aquatic neoreptiliomorphs lay their eggs underwater or keep them within their mothers.

Reproduction
Unlike their ancestors who are anamniotic, neoreptiliomorphs are characterized by having an egg equipped with an amnion, an adaptation to lay eggs on land, convergent with amniotes. Neoreptiliomorph embryos, whether laid as eggs or carried by the female, are protected and aided by several extensive membranes. In the non-amphibian crocophibians, these membranes include a sticky yolk-like membrane that surrounds the fetus and protrudes out of the eggs and later dissolves, this membrane is useful to protect the egg from predators and is also not too hard for the baby to come out of.

History
The first neoreptiliomorphs, referred to as "archaeoreptiliomorphs", had a striking resemblance to salamanders but with scales and evolved from the lissamphibians ("living amphibians") in the Middle Hesperocene era. The eggs of the archaeoreptiliomorphs could survive in dry environments allowing them to thrive into other habitats. The eggs also require a short amount of time to hatch, allowing the reptiliomorphs to diversify.
