“…In contrast, injuries hypothesized to be the result of intraspecific biting are localised on the cranium, implying the animals faced each other directly, or lined up side by side and thus potentially in some form of ritualised combat. In the case of the specimen here, despite the lack of much of the postcrania and the injured dorsal rib, it Jenny Clack 19/3/2015 10:58 Formatted: Right: 0.63 cm is clear that numerous injuries were inflicted on the skull at some point (and perhaps on multiple occasions) some considerable time before death (see Straight et al, 2009).…”

Trace marks on the bones of non-avian dinosaurs may relate to feeding by large carnivores or as a result of combat. Here the cranium and mandible of a specimen of Daspletosaurus are described that show numerous premortem injuries with evidence of healing and these are inferred to relate primarily to intraspecific combat. In addition, postmortem damage to the mandible is indicative of late stage carcass consumption and the taphonomic context suggests that this was scavenging. These postmortem bites were delivered by a large bodied tyrannosaurid theropod and may 2

“…The fracture is pre-mortem as it shows advanced, but not total, repair. Healing rates of bone fractures in dinosaurs are unknown; however, some evidence points towards healing rates similar to extant avians (Straight et al 2009). This cervical vertebra provides evidences for a broken neck that was not immediately fatal, indicating the injured animal lived on for at least weeks or months after being injured.…”

“…Such tools have allowed palaeopathologists to both increase the sample size and the integrity of their diagnoses through non-destructive internal analysis [5,7–10]. Here, we present XMT data from the pathological hadrosaur ulna and radius (NJSM GP11961) to (i) accurately diagnose the pathological condition, and (ii) digitally conserve a rare and important specimen.…”

First diagnosis of septic arthritis in a dinosaur

Identification and interpretation of pathologies in the fossil record allows for unique insights into the life histories of extinct organisms. However, the rarity of such finds limits not only the sample size for palaeopathologic studies, but also the types of analyses that may be performed. In this study, we present the first occurrence of a palaeopathology in a vertebrate from the Mesozoic of the East Coast of North America (Appalachia), a pathologic ulna and radius of an indeterminate hadrosaur from the Navesink Formation (New Jersey). X-ray microtomography allowed for both detailed and more accurate diagnosis of the pathologic condition as well as virtual conservation of the specimen. Based on extant archosaurian comparisons, the hadrosaur was diagnosed with severe septic arthritis affecting the proximal ulna and radius. Diagnosis was based on erosion of the joint and highly reactive periosteal bone growth and fusion of the elements. To the best of our knowledge, this is the first recorded account of septic arthritis in dinosaurs. The severity of the pathology suggests the animal suffered with this condition for some time before death. Unfortunately, only the ulna and radius were found. Thus, the extent to which the condition spread to other parts of the body is unknown.
