One adaptation was hard-shelled eggs that were impervious to water loss. This allowed the embryo to survive without the egg having to be laid in water.
They have hard outer skin and that helps them to survive in the heat and dryer places than the amphibians.

no, the reptiles evolved from fish
It's possible that early reptiles did not, but modern reptiles certainly do.

Agriculture. More food allowed specialisation, cities and settled government.
Early Americans were isolated from the rest of the world due to geographical barriers like oceans and mountains, which limited contact with other societies. This isolation allowed them to develop in ways similar to other early humans through independent innovations and adaptations to their environment. They faced similar challenges such as securing food, building shelter, and establishing social structures, leading to comparable strategies and solutions.
The amniotic egg allowed early reptiles to move away from waterside habitats and colonize dry regions. It allowed reproduction on land by preventing the embryo from drying out, so eggs could be laid away from the water.
Hadrosaurs were able to eat tough vegetation because of the adaptations that allowed them to chew. Plants they ate may have included conifers, cycads, ferns, horsetails, and early grasses.
The development of agriculture allowed early people to transition from a nomadic lifestyle to a settled lifestyle. It provided them with a stable food source, which allowed for the development of permanent settlements and the growth of civilization. It also led to the development of more advanced technologies and social structures.
