ABSTRACT

A male specimen of Mirounga leonina Linnaeus, 1758 age estimated betvveen 7-8 years old, collected at Santa Vitória do Palmar, Rio Grande do Sul State, soutiiernmost Brazil (32º44'S and 53º22'W) is presented. Ali the skeleton was recovered except the rostral region. It shows an advanced osteomyelitis in the lefl dentary, extending from the synfisis until the middle portion of the body; as well as Scheuermann disease at lumbar vertebrae. Such diseases could explain its presence at that locality, where rt was shot. The bullct was recovered from the rostrum, and might be responsible for death. This is the first vhlually complete skeleton of M. leonina recovered from Brazilian coast.

Key words: Pinnipedia, Phocidae, Mirounga leonina, osteomyelitis, Scheuermann disease, injury.
