Diagnosis
Reference | Diagnosis | |
---|---|---|
H. -K. Yeh 1990 | The description for the type suggests that several characters relate to C. baenoides while others approach C. zigongensis. Those characters that differentiate this species from the other two include a very rounded entoplastron and an extremely medially compressed mesoplastron. | |
H. Tong et al. 2012 | A genus of the Bashuchelyidae, carapace length about 200 mm, with the following combination of characters: carapace elongated oval and low (1) with shallow cervical notch (2); all vertebrals broad, second to fourth vertebrals almost twice as wide as long (3); plastron with wide anterior lobe, and short and wide posterior lobe (4); one pair of reduced mesoplastra meeting on the midline and included entirely in the abdominal scute (5); epiplastron squarish (6) with long midline contact (7); entoplastron diamond-shaped and slightly longer than wide (8); intergulars excluded from entoplastron (9). Differs from Bashuchelys by characters 3–9. |
