Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Q. Pang and Z. Cheng 2000 | A large sauropod about 20 m in length and 5 m in height. The strong teeth are peg-like and the tooth crown is high; the ratio between the length of the tooth crown and that of the tooth root is 3 to 1. The cervical vertebrae are opisthocoelous with a wide-flat ventral flute, and their pleurocoels are wide and deep and their neural spines bifurcated. The dorsal vertebrae are also opisthocoelous with deep oval-shaped pleurocoels; their neural spines high and unbifurcated. The sacra are 5 in number and their spines combined into a plate. The caudal vertebrae are clearly amphicoelous; their neural arches are situated on the front half of the centrum and the spines unbifurcated. The chevrons are Y-shaped and unbifurcated distally. The scapula is long and its distal dilation is not pronounced. The humerus is robust and proximally slightly flattened. The ilium is very large, long fan-shaped, with a pubic peduncle situated slightly anterior of the middle part of the ilium’s lower edge, and the ischic peduncle undeveloped. The pubis is broad, nearly plate-like, with a distinctly expanded proximal part. The ischium is yoke-like and its shaft is short and flat. The femur is straight, long, narrow and flat, with a well-developed, oblate femur head, and the fourth trochanter is dilated and located on the posterior inner lateral edge of the slightly upper part of the shaft’s middle. The tibia and fibula are long and flat. The length ratio between the humerus and the femur is 0.78 to 1, while that between the radius and the humerus and that between the tibia and the femur are 0.77 to 1 and 0.75 to 1 respectively. |
