Beschreibungen/Notizen

• Palaeopathological analyses have great potential to provide insights into dinosaurs' palaeobiology and life histories, but few cases have been reported in China. In this study, we report on four pathological sauropod ribs excavated in the same quarry of the Middle Jurassic in Yunyang County, Chongqing, southwest China. Based on morphological observation, computerised tomography (CT)-based energy spectrum data, and image analyses, three types of pathology were identified: traumatic fracture, fracture after bone infection, and osteosclerosis. This study increases the knowledge of dinosaur pathology, especially of Jurassic sauropods, and highlights the use of energy spectrum CT in palaeopathological studies.
