Close-up of the traumatic lesion observed in the right squamosal bone of Big John, a fossilized specimen of the dinosaur species Triceratops horridus. This image shows plaque-like deposition of reactive bone (white arrows) and lytic lesions (black arrows) on the surface around the lesion. These suggest that the lesion was surrounded by newly-formed bone and, therefore, had started to heal. This image was originally published as Figure 1c in the following journal article: Ruggero D’Anastasio, Jacopo Cilli, Flavio Bacchia, Federico Fanti, Giacomo Gobbo & Luigi Capasso (2022) Histological and chemical diagnosis of a combat lesion in Triceratops Scientific Reports, 12, 3941 (2022).
