Warkalania carinaminor
Discussion
Etymology. Carina, ridge, and minor, small, in reference to this species having scale areas A,B, and C as small ridges, a condition unique among meiolaniids.
Taxonomy
Warkalania carinaminor was named by Gaffney et al. (1992). Its type specimen is QMF 22649, a partial skull (right squamosal), and it is a 3D body fossil. Its type locality is Pancake Site, which is in an Oligocene fluvial limestone in the Carl Creek Limestone Formation of Australia. It is the type species of Warkalania.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. S. Gaffney et al. 1992 | As for genus: Meiolaniid with B scale area (encompassing the largest horn in other meiolaniids), delimiting a low, horizontal ridge, not a recurved horn as in Meiolania nor a large lateral projection as in Niolamia (including Crossochelys) and Ninjemys oweni; A, B, and e scales formed into low, horizontal ridges, small and roughly similar in size to each other, in contrast to all other meiolaniids; A scale area not as protuberant as in Niolamia and Ninjemys oweni but more protuberant than in Meiolania; e scale area a low ridge, higher than in Meiolania but lower than in the other meiolaniids; X scale small, and D scales in midline contact as in Ninjemys oweni and Meiolania. | |
| J. Sterli 2015 | Warkalania carinaminor is differentiated from other meiolaniids by the presence of processes in the squamosal and the scutes covering them forming low and horizontal ridges rather having prominent extensions away from the skull, scutes A, B and C of similar size and scute X small |
