Edaphosaurus (SciiFii)

Edaphosaurus abaraphagentle (meaning "pavement lizard by gentle giant") is a species of edaphosaurid synapsid with a distinctive sail along its back, similar to the related coexisting hunter, Dimetrodon, that first lived in the late Carboniferous and early Permian and was once extinct, but has been brought back through genetic engineering by SciiFii.
