Age Determination in the Spotted Skunk

Five indices of age in the spotted skunk were studied. Lens weight is the measurement most useful in distinguishing between juveniles, subadults, and adults. Obliteration of cranial sutures is the next best index in specimens less than 10 to 11 months old. Observations of ankylosis of the epiphysis to the diaphysis of long bones are useful only in separating animals less then 8 months of age from older animals. Placental scars, and weight and shape of the baculum also are useful provided the investigator is aware of the biological factors that influence these structures.
