Which of these is an example of the creatures that later developed into the first amphibians of Earth?

In 1938, a fish caught in South Africa happened to be a Coelacanth, which was thought to be extinct. These animals called lobefins evolved into the first amphibians that lived on both land and water. There are no specimens of these left with us. However, these were ancestors of modern-day frogs and salamanders. The amphibians further evolved into reptiles.
