360 to 150 millions years ago.
They were abundant on Earth during the Carboniferous.
The labyrinthodont was 359-237 million years ago, lystrosaurus was 298.9-257.9 million years ago, and the duck billed dinosaur was 69 million years ago. That makes the labyrinthodont older.
I assume the reason is connected to Pangaea, Pangea, Super Continent, etc.
Reptiles evolved from labyrinthodont amphibians around 315 million years ago. Hence all amniotes (reptiles, birds, and mammals) descend from the labyrinthodonts.
Labyrinthodonts were primarily amphibious vertebrates that lived during the Late Devonian to the Late Triassic periods, approximately 370 to 200 million years ago. They originated in freshwater environments, such as rivers and lakes, and are believed to have inhabited regions that are now parts of Europe, North America, and Africa. Their fossils have been found in various sedimentary deposits, indicating a widespread distribution during their time.
Zygosaurus was not a dinosaur. It was not even a reptile, but a mid-Permian labyrinthodont amphibian which was dragging itself around probably 40-50-million years before the first dinosaurs showed up. Taxonomically, it was a Dissorophid Temnospondyl and was not in the evolutionary line leading to dinosaurs, modern reptiles, or mammals.
