What is another word for stereospondyli?
Pronunciation: [stˈɛɹɪˌə͡ʊspəndˌɪli] (IPA) 
Stereospondyli is a term used to describe an extinct order of amphibians that lived during the Carboniferous, Permian, and Triassic periods. Synonyms for stereospondyli include the terms "stereocephali" and "amphibamiformes." These ancient amphibians had distinctive vertebrae that were composed of two main parts: a centrum and a neural arch. The centrum was a cylindrical bone that made up the bulk of the vertebra, while the neural arch was a bony structure that surrounded the spinal cord. Today, the stereospondyli are one of the most diverse and abundant groups of fossil amphibians, with over 200 species identified so far. They were once widespread across the world, and their fossils have been found on every continent except Antarctica.
