Background:the Red Fox Vulpes vulpes is the most common and wide spread wild carnivore in Egypt. Materials and methods:we examine a museum sample of 179 specimens from different parts of Egypt to determine age structure using dentine layers counting method. Specimens were grouped into three population groups according to their geographical region of origin. Results:the average age of foxes in the sample was 1.46 years and ranging from 1 to 7 years of age. Differences in age structure of populations from the three geographical regions and differences between sexes are presented and discussed.
