Dermal bone that forms the antero-lateral part of the lower jaw. It first appears around the anterior end of Meckel's cartilage (5.1 mm NL). In the adult, the dentary meets its counterpart anteriorly at the mandibular symphysis. The dentary abuts the retroarticular posteriorly, and it surround the anguloarticular. The dentary is connected to the maxilla by the maxillo-mandibular ligament. Dentary teeth are absent in cypriniforms, but are present in other ostariophysans. [ GOC:ymb ORCiD:0000-0002-9900-7880 ]
