Jainemys pisdurensis
Taxonomy
Carteremys pisdurensis was named by Jain (1977). Its type specimen is ISI R200, a partial skull, and it is a 3D body fossil. Its type locality is Pisdura Hill (sandstone), which is in a Maastrichtian terrestrial claystone/sandstone in the Lameta Formation of India.
It was recombined as Shweboemys pisdurensis by Jain (1986); it was recombined as Jainemys pisdurensis by Joyce and Bandyopadhyay (2020).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. G. Joyce and S. Bandyopadhyay 2020 | Jainemys pisdurensis furthermore differs from podocnemidids by lacking an interorbital groove and an interparietal scale. Among kurmademydines, Jainemys pisdurensis can be differentiated from Kurmademys kallamedensis by having a more elongate skull, a greater posterior extension of the frontals, more anteroposteriorly elongate palatines that only contribute minorly to the triturating surfaces, remnants of the vomer between the maxillae, presence of a prootic and opisthotic contact in the upper temporal fossa, which hinders contact between the quadrate and supraoccipital, a more equilaterally pentagonal basisphenoid, and a much smaller fossa pterygoidea and from Sankuchemys sethnai by having a more elongate skull, a greater posterior extension of the frontals, presence of a prootic and opisthotic contact in the upper temporal fossa, which hinders a contact between the quadrate and supraoccipital, broader triturating surfaces, by lacking a posterior vomeral process that contacts the palatines, and by having more expanded palatines, a more equally sided pentagonal basisphenoid, and a shorter basioccipital. |
