Herrerasaurus - Paleobiology - Paleopathology

Paleopathology

In a 2001 study conducted by Bruce Rothschild and other paleontologists, 12 hand bones and 20 foot bones referred to Herrerasaurus were examined for signs of stress fracture, but none were found.

PVSJ 407, a Herrerasaurus ischigualastensis had a pit in a skull bone attributed to a bite by Paul Sereno and Novas. Two additional pits occurred on the splenial. The area around these pits are swollen and porous, suggesting the wounds were afflicted by a short-lived non-lethal infection. Because of the size and angles of the wound, its likely that they were obtained in a fight with another Herrerasaurus.
