|---|---|---|
| Z. Zhu et al. 2024 | A large (~6 m long) ankylosaurid dinosaur, distinguished from other ankylosaurids by three autapomorphies: the middle shaft and distal end of the ischium are expanded; the ratio of width of distal end to minimum shaft width is greater than 3 in humerus, the maximum length of femur to humerus length ratio is about 1.45), as well as character combinations that the centra of anterior caudal vertebrae in anterior view is heart-shaped (common in nodosaurids, but is absent in ankylosaurids); the dorsal surface of scapula is straight (also present in Akainacephalus, Chuanqilong, Crichtonpelta, Euoplocephalus, Liaoningosaurus, Jinyunpelta and Pinacosaurus); the scapulocoracoid has a large medial brace (the maximum height of medial brace is greater than or equal to the maximum length of the scapula glenoid, also present in Crichtonpelta); the humeral head and deltopectoral crest are separated by a distinct notch anteriorly (only present in Ankylosaurus and Scolosaurus). |
