Diagnosis
ReferenceDiagnosis
G. L. Georgalis et al. 2021Stigmochelys crassa can be diagnosed as a member of Testudinidae, Geochelona, and Stigmochelys by the full list of shell characters provided for these clades above. Stigmochelys crassa can be differentiated from other species of Stigmochelys by its large size (plastron length exceeding 70 cm), pectorals with maximum width at the midline and narrowing considerably on either side of the midline, gulars crossing the entoplastron, pectorals not reaching the entoplastron, and longer hyoplastra.
