But the real number is likely higher, because we couldn’t assess all bones from all 34 individuals. Of the 34 partial skeletons of Genyornis, four showed signs of bone infections. ![]() Osteomyelitis is a chronic bacterial infection of bone tissue, which can be caused either by trauma that lets microbes directly enter bone tissue, or via transmission from infected soft tissues nearby. Infection on the leg of Genyornis newtoni and a life reconstruction of the injured bird.
