Temnospondyli (from Greek (temnein, to cut) and (spondylos, vertebra)) is a diverse order of small to giant tetrapods-often considered primitive amphibians-that flourished worldwide during the Carboniferous, Permian, and Triassic periods. A few species continued into the Cretaceous. Fossils have been found on every continent. During approximately 210 million years of evolutionary history they adapted to a wide range of habitats including fresh water, terrestrial, and even coastal marine environments. Their life history is well understood with fossils known from the larval stage, metamorphosis, and maturity. Most temnospondyls were semiaquatic, although some were almost fully terrestrial, returning to the water only to breed. These temnospondyls were some of the first vertebrates fully adapted to life on land. Although temnospondyls are considered amphibians, many had characteristics such as scales, claws, and armor-like bony plates that distinguish them from modern amphibians.
