Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. F. Kammerer and K. D. Angielczyk 2009 | Two autapomorphies of Emydopidae are present in the data set of Angielczyk (2007): (1) lateral anterior palatal ridges present; (2) upper postcanine teeth located near lateral margin of the maxilla. One autapomorphy of Emydopidae is present in the data set of Fröbisch (2007): (1) maxillary non-caniniform teeth located near lateral margin of the maxilla. The addition of Emydops oweni to the data set of Fröbisch & Reisz (2008) renders the status of that character uncertain, because it could not be scored using the available specimens of E. oweni. However, one emydopid autapomorphy does exist in the data set of Fröbisch & Reisz (2008): (1) squared-off profile of occiput in posterior view present. Recent diagnoses of Emydops itself can be found in Keyser (1993; called Emydoses therein), King & Rubidge (1993), Ray (2001), and Fröbisch & Reisz (2008), with additional information in Angielczyk et al. (2005). The jaw of Emydops is the single mostdistinctive part of its skeleton, and is characterized by a shovel-shaped symphysis, weak posterior dentary sulci, a small number of medially located postcanine teeth, and a large, triangular lateral dentary shelf. |
