Variations in number of teeth and asymmetry of the skull in the wolf

Analysis was made of the teeth in 234 wolf skulls obtained from Polish territory and from the eastern part of the Bialowieza Primeval Forest (USSR). Authors describe three groups of deviation^ from typical tooth pattern in wolves: polydonty, oligodonty and others types of tooth anomalies occurring when the normal number of teeth was present. There is a similar frequency of polydonty and oligodonty in! Lublin voivodship and more southern voivodships Krakow and Rzeszow. In different geographical regions were observed a particular deviations from the teeth pattern, e.g., bilateral occurrence of additional i2I2 in skulls from the Bialystok voivodship arid the eastern part of Bialowieza Primeval Forest; the bilateral absence of M3 found only in the south Poland and bilateral skeweness of P3 occurred only in wolves from Lublin voivodship. An increased number of teeth occurs more often in males than; in females.
