Diagnosis.—Modified from Ji et al. (2015) and discussed in Økland et al. (2018). Premaxilla forms the anterior margin of external naris (also present in Mixosaurus panxianensis Jiang, Schmitz, Hao, and Sun, 2006 ); nasal region with a pronounced narial shelf; maxillary tooth implantation with sockets, dental groove absent posteriorly (completely absent in Phalarodon fraasi ); significant heterodonty between anterior and posterior teeth in the maxilla (not extreme in Phalarodon atavus ); teeth with laterally compressed horizontal section (circular in Phalarodon callawayi ); posterior tooth crown flat (conical in P. atavus ).
