摘要: 记述了自贡地区的和平永川龙（和平中华盗龙）（Yangchuanosaurus(Sinraptor)hepingensis）ZDM 0024存在一断裂后愈合的肩胛骨，这是中国兽脚类病理学的首次详细记录。该肩胛骨有骨皮质不连续、成角畸形、骨痂形成，符合骨折后愈合的表现，而且从其病理特征看，病理性骨折的可能性很小，直接暴力所致骨折的可能性极大。还分析了同时期动物群中可能存在暴力施加者，拥有尾锤的合川马门溪龙（Mamenchisaurus hochuanensis）可能性最大，这为和平永川龙的骨折提供了一种有趣的解释。

Abstract: A scapula with healed wound of Yangchuanosaurus (Sinraptor) hepingensis ZDM 0024 from Zigong Dinosaur Museum of China is described. This is the first detailed description on pathology of theropoda in China. The discontinuous cortical bones, angular deformity and bony callus suggest an external force-caused wound healing in this bone, rather than a pathological fracture. Mamenchisaurus hochuanensis with tail club among the contemporary fauna is probably the candidate for the assault. This presents an attractive explanation to the bone fracture of Yangchuanosaurus hepingensis.
