Chedighaii barberi
Taxonomy
Podocnemis barberi was named by Schmidt (1940). Its type specimen is FMNH P26055, a shell (nearly complete shell), and it is a 3D body fossil.
It was recombined as Bothremys barberi by Thurmond and Jones (1981); it was recombined as Chedighaii barberi by Gaffney et al. (2006); it was considered an invalid subgroup of Bothremydina by Noto et al. (2022).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. S. Gaffney et al. 2006 | A member of the genus Chedighaii differing from the only other species, Chedighaii hutchisoni, in the following characters: suborbital maxillary plate shallower; triturating surfaces narrower, preorbital part of skull narrower; other differentiating features: premaxilla protuberant, unique among Bothremydini (but not known in C. hutchisoni); apertura narium externa faces strongly anterodorsally, more than in any other Bothremydini (not known for C. hutchisoni); labial ridge straight, relatively thin and acute, in contrast to Bothremys; carapace low, more round than oval, broader posteriorly; nuchal notch present; six or seven neurals; plastron with short and wide anterior lobe; posterior lobe with lateral margins tapering posteriorly; humeropectoral sulcus posterior to the epihyoplastral suture, crossing entoplastron; pectoroabdominal sulcus crossing mesoplastron; first vertebral tapered posteriorly to lie in part on nuchal bone, unique among bothremydids; costal bones 2–4 short in relation to width, as in Taphrosphys but in contrast to Cearachelys; xiphiplastral notch broad and U-shaped, xiphiplastra end in rounded projections; pubic scar short and wide, ischiac scar triangular to curved, separated from xiphiplastral edge. |
