Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. F. Kammerer and K. D. Angielczyk 2009 | Autapomorphies of Myosauridae recognized by Angielczyk (2007), Fröbisch (2007), and Fröbisch & Reisz (2008) are: (1) nasal bosses absent; (2) palatal surface of the palatine without evidence of a keratinized covering. The most recent detailed diagnoses available for Myosaurus can be found in Cluver (1974) and Hammer & Cosgriff (1981). However, these workers did not include what is perhaps the most distinctive feature of the skull of Myosaurus in their diagnoses, a posterior median palatal ridge that is Tshaped in cross-section and flanked by two laterally enclosed channels that lie between it and the palatal grooves that characterize all emydopoid dicynodonts. Cluver (1974) did however discuss these features in some detail elsewhere in his redescription of Myosaurus. |
