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 theropod
pathology 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.
