Ambedus
''Ambedus'' is an extinct genus of diadectid reptiliomorph. Fossils have been found from the Early Permian Dunkard Group of Monroe County, Ohio. The type species ''A. pusillus'' was named in 2004. The genus name comes from the Latin word ''ambedo'' meaning "to nibble", in reference to its herbivorous diet. The specific name ''pusillus'' means "tiny" in Latin. ==Description== ''Ambedus'' is a small diadectid known only from maxillae and dentary bones. It is considered the most primitive diadectid because unlike other forms it had a small, shallow lower jaw and many simple, conical teeth. It was also smaller than the later, rather bulky diadectids. Later diadectids have deep jaws with few teeth and forward-projecting incisiforms at the tips of the jaws for consuming plant material, and a corresponding greater girth.
