Diagnosis
ReferenceDiagnosis
W. G. Joyce et al. 2009Characters that are derived relative to non-testudinate amniotes: presence of a plastron, carapace and multi-element neck and tail armour; dorsal centra hourglass-shaped, platycoelous, with distinct ventral keel; and dorsal ribs contact two dorsal vertebrae. Derived and/or autapomorphic characters: dorsal ribs compressed, oriented vertically and only lightly associated with overlying dermal armour; double contact between dorsal vertebrae and dorsal ribs only incipient; carapace and most of plastron laminar in thickness; carapace with distinct medial ridge that widens towards posterior; plastron with sloping inguinal notch; and neck armour prongs form angular cones.
