| E. S. Gaffney et al. 2006 | A bothremydid pleurodire of the tribe Bothremydini with the following unique feature within Bothremydini: vomer widely separated frommaxilla, associated with large apertura narium interna, in contrast to vomer-maxilla nearly or in contact, as in all other Bothremydini; other differentiating characters: anterior projection of prefrontal present, in contrast to Foxemys, Polysternon, and Rosasia; apertura narium externa facing anterodorsally to a greater extent than in Bothremys and other Bothremydini (except possibly the incomplete Zolhafah); orbit small, as in Bothremys and in contrast to all other Bothremydini; orbits face strongly upward, as in Bothremys and in contrast to other Bothremydini; prefrontal-palatine contact present, as in Bothremys and Araiochelys and in contrast to all other Bothremydini; dorsal process of maxilla narrow, in contrast to Bothremys but in common with all other Bothremydini; sulcus palatinopterygoideus low, as in Bothremys but in contrast to all other Bothremydini; fossa orbitalis enlarged posteriorly, as in Bothremys, Araiochelys, and Rosasia and in contrast to Foxemys and Zolhafah; ridge forming lower margin of orbital rim high, as in Bothremys arabicus, Polysternon, Zolhafah, Rosasia, and Araiochelys but in contrast to other Bothremys species; suborbital maxillary plate deep, as in Bothremys and in contrast to all other Bothremydini; triturating surface pit absent; no exposure of jugal on triturating surface; midline depression on ventral surface of premaxilla very wide, as in Bothremys arabicus and Zolhafah and in contrast to other Bothremys, Rosasia, and Araiochelys; fossa pterygoidea absent; incisura columellae auris closed; foramen posterius canalis carotici interni formed by pterygoid and quadrate; basisphenoid-quadrate contact very narrow, as in Bothremys and in contrast to all other Bothremydini; lower jaws with triturating surface pits; shell (known only from C. barberi) typical of Bothremydina, pectoral scales well posterior to epiplastra, in contrast to Foxemydina; pectoral scales in contact with mesoplastra, in contrast to Foxemydina and Araiochelys; peripheral 1 contact to costal 1 wide, as in Rosasia and in contrast to narrow in Foxemydina and Araiochelys; anterior lobe of plastron does not reach anterior carapace margin, as in Rosasia and the Foxemydina and in contrast to the Cearachelyini. |
