In the Late Carboniferous, reptiles were able to move into new habitats due to their adaptations to terrestrial life, including waterproof skin and the ability to lay eggs on land, which reduced their dependency on aquatic environments. These adaptations allowed them to exploit diverse terrestrial ecosystems and occupy niches that were previously inaccessible to amphibians. Additionally, the rise of gymnosperms provided new food sources and habitats, facilitating their spread and diversification.
