Studies were carried out with 135 skulls of wild red foxes inhabited the region of the Sirnena Sredna Gora mountains. Aim of the research was the age- and sex-relation of 11 basic craniometric measurements. Strongly expressed sexual dimorphism was found out in animals of 1 – 2 years of age. Sexual differences were less expressed in animals younger than 1 year and older than 3 years of age when skulls were unimorphous. There was correlation between sex and the zygomatic width. The craniometric measurements studied depend much more on sex than on age.

Key words: red fox, cranial measurements, sex– and age-dependent dimorphism
