Diagnosis
ReferenceDiagnosis
P. A. Meylan and W. Sterrer 2000North American land tortoises with very well developed dermal armour, with those ossicles over the tail united and, in combination with enlarged transverse processes of the caudal vertebrae, forming a caudal buckler (Auffenberg, 1963, 1974) or a tail club (DMNH 1600 and 1601); nuchal scute longer than wide; posteriorly excavated epiplastra; medially narrowed pectoral scutes; large inguinal scute in broad contact with femoral scute; transverse ridge (=commissural ridge) on premaxilla, median maxillary ridge and lingual ridge extending onto premaxilla; foramen praepalatinum obsolete; acromion process forming very large angle (110°) to body of scapula.
