Detailed explanation-1: -The connecting link between amphibians and reptiles is Seymouria which was an animal living in the Permian period on both the land and in water. It is said to be a connecting link because its larval stages show amphibian-like features whereas its adult stages show reptile-like features.

Detailed explanation-2: -Seymour is an extinct genus. It was dependent on water and needed a moist environment for development just like amphibians. And the skeletal system shows a resemblance to primitive reptiles. As it shows characteristics from both the animal groups, it is believed to be a connecting link between Amphibians and reptiles.

Detailed explanation-3: -Though no longer considered the most primitive reptile, Seymouria is still an important transitional fossil documenting the acquisition of reptile-like skeletal features prior to the evolution of the amniotic egg, which characterizes amniotes (reptiles, mammals, and birds).

Detailed explanation-4: -Seymouria is a connecting link between amphibians and reptiles.

Detailed explanation-5: -The Seymouria was initially classified as a reptile in the early 1940s because of its dry scaly skin. After a fossil was found with gill impressions, it was then classified as an amphibian, although that might not even be the whole story.
