We report the first occurrence of congenital scoliosis in an early Permian aquatic parareptile, Stereosternum tumidum from Parana ́ state, Brazil. The spine malformation is caused by a congenital hemivertebra. These observations give insight into the biomechanical aspects of underwater locomotion in an axial skeleton-compromised aquatic amniote. This is the oldest record of a hemivertebra in an aquatic animal.
