ABSTRACT

The studies aimed at demonstration of uniqueness of American mink masticatory apparatus. The craniological relationships were defined in a sample of 25 skulls of adult minks (18 females, 7 males). The standard data, including 21 measurements, provided material for subsequent statistical analyses. The results demonstrated sexual dimorphism of some crania parameters. Most of characters of masticatory apparatus manifested high correlation with the total cranial length. In turn, equations of allometric analysis were constructed, in which the total cranial length was selected to represent the independent variable. Total lengths of dental rows, maxilla and mandible were markedly abbreviated, as compared to the total cranial length. In parallel, pronounced development was noted of the posterior part of mandible, which pointed to an extensive area for attachment of masticatory muscles. Length of hard palate exceeded markedly the length of dental rows. An isometry or proportional growth was noted of the total cranial length and the length of hard palate.

Key words: craniometry, skull, allometry, American mink.
