Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. S. Gaffney et al. 2006 | A bothremydid pleurodire of the tribe Bothremydini with the following unique feature within the Bothremydini: unusually large orbital margin (possibly also in Zolhafah); other differentiating characters: apertura narium externa oval without prefrontal and premaxillary projections, in contrast to Zolhafah, Bothremys, Araiochelys, and Chedighaii; dorsal process of maxilla narrow, in contrast to Bothremys; fossa orbitalis enlarged posteriorly, in contrast to Zolhafah and Foxemys, but as in Bothremys and Chedighaii; midline depression on ventral surface of premaxilla narrow, as in Bothremys, not wide, as in Zolhafah, Polysternon, Foxemys, and Araiochelys; triturating surfaces triangular and very wide, as in Zolhafah, Foxemys, and Bothremys; triturating surface pit present, as in Zolhafah, without complete posterior wall, in contrast to complete pit seen in Bothremys and Araiochelys; ridge forming lower orbital rim present, in contrast to Bothremys; jugal forms tip and posterior part of triturating pit, as in Zolhafah; lateral edge of maxilla curved, in contrast to Araiochelys; snout pinched, in contrast to Zolhafah; vomer-maxilla contact extensive, as in Foxemys and Bothremys cooki but in contrast to Zolhafah and other Bothremydini; fossa pterygoidea shallow, in contrast to deep in Foxemys and Polysternon; incisura columellae auris closed, as in all Bothremydini except Foxemys and Polysternon; condylus mandibularis at level of condylus occipitalis, in contrast to Polysternon and Araiochelys; quadrate-maxilla contact present, in contrast to Foxemys, Polysternon, and Chedighaii, but as in Bothremys and Araiochelys; foramen posterius canalis carotici interni formed by pterygoid and basisphenoid, in contrast to Chedighaii, Araiochelys, and Bothremys; carapace rounder than in Cearachelys, with nuchal embayment (see Carrington da Costa, 1958: fig. 1); seven neural bones; costals 7 and 8 meet on midline; plastron with rounded anterior lobe; pectoral scale not reaching entoplastron; gular scale small and restricted to anterior part of epiplastron; pectoral scale reaches mesoplastron; posterior lobe tapering, not parallel-sided. |
