If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
J. Sterli 2015Meiolania platyceps shares with other members of the clade Meiolania the presence of recurved B horns and the absence of a continuous shelf formed by scutes A, B and C. Meiolania platyceps is differentiated from Me. brevicollis and Me. mackayi by the presence of a relatively wider horn core B, the presence of a parasagittal ridge on the premaxillary triturating surface and the absence of ventral keels in cervical vertebrae 5 and 6. Meiolania platyceps is differentiated from Me. brevicollis by the higher angle of the posterior projection of the horn core B, the larger horn core A, the relatively longer, lower and wider cervical vertebrae and the relatively low and flat neural spine of the axis. Meiolania platyceps is differentiated from Me. mackayi by the presence of relatively more robust limb bones. Meiolania platyceps is about 30% larger than Me. mackayi and about 10% to 20% smaller than Me. brevicollis.

Comments: The palate of Me. platyceps is decorated by several rows of serrated ridges, which is indicative of herbivorous dietary preferences by analogy to numerous extant testudinoids (Ernst and Barbour 1989; Joyce and Bell 2004).s
