|---|---|---|
| P. M. Datta et al. 2000 | As for type and only species: Shell low, oval with tapered posterior, surface smooth, lacking ornamentation; nuchal bone large, almost encompassed by the first vertebral scute; nine neurals, broad and drum-shaped; eight paired costals arranged almost in parallel, first costal articulating only with first and second peripherals; eleven paired peripherals; two large and wide suprapygals, the anterior triangular, the posterior crescent-shaped; scutes thin, five broad vertebrals, the third one widest, covering half of the shell width, the fifth completely enclosed by the last paired marginals and paired supracaudals; cervical scute present, V-shaped with incurved anterior margin; no supramarginal scutes (shared with Kayentachelys); eleven paired, squarish, marginal scutes; four paired, pleural scutes longer than broad (shared with Proganochelys); plastron relatively small and narrow with truncated anterior margin not protruding beyond the cervical scute; a very small gap between carapace and plastron all along the anterior margin; plastron having eleven elements including a pair of mesoplastra; entoplastron broad, spatulate, extending to the anterior margin of the shell and separating the epiplastra (shared with Kayentachelys); paired gular scutes extend to entoplastron almost a third of its length; one pair of mesoplastra, narrowing towards the mid-line; plastro-carapace bridge one-third of shell length. |
