Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. W. Evers et al. 2021 | Arundelemys dardeni can be diagnosed as a member of Paracryptodira based on the presence of a characteristic combination of derived and symplesiomorphic features. These include the presence of skull sculpturing (also present in some sinemydids; Brinkman & Peng, 1993; Zhou, Rabi & Joyce, 2014; and some xinjiangchelyids: Tong et al., 2019); a relatively strong lateral orbit orientation; the retention of relatively large nasals paired with their partial posterior separation by the anterior frontal processes (the nasals of early Testudinata or Meiolaniformes are in medial contact with one another across their entire length: Gaffney, 1990; Sterli, 2015; and the nasals of sinemydids are small: e.g., Rabi et al., 2013; Li et al., 2019); a unique combination of jugal features that includes a dorsally raised jugal position (as in xinjiangchelyids, but unlike in meiolaniforms; varies in sinemydids: see Brinkman & Wu, 1999; Li et al., 2019) and its exclusion from the orbital margin (unlike in sinemydids, xinjiangchelyids, meiolaniforms); retention of a posteriorly open incisura columellae auris; and a unique combination of traits surrounding the embedding of the carotid artery, including the presence of a carotid pit, absence of internal carotid artery embedding, and the absence of a palatine artery canal or interpterygoid vacuity indicating the reduction of the respective artery (retained in Uluops uluops among paracryptodires: Rollot, Evers & Joyce, 2021). |
