The objective of the present study was to define the normal radiographic anatomy of the healthy African Brush-tailed Porcupine appendicular skeleton which can help to identify anatomic features of that animal and comparing it with other small mammals, such as the dog and cat. Fore (two male and two females) free-living porcupines (Atherurus africanus) from the El-jabal alakhdar region of Libya were selected for this study. Lateral , craniocaudal and caudocranial radiographs from the thoracic and pelvic limbs were obtained. The important anatomic structures of the appendicular skeleton were revealed, seen clearly and labeled in two corresponding photographs of radiograph and bones of porcupine limbs. The various boney structures of the limbs were recorded. The radiographs from these porcupines were compared with the normal canine and feline skeletal radiographic anatomy.
