Аннотация: Morphometric variability of cave and brown bears and their ancestors (Ursus minimus and U. etruscus) is examined using multivariate statistics based on measurements of 679 mandibles from 90 localities in Northern Eurasia. The variability is dependent on sexual dimorphism in size: it is well seen in big cave bears (U. spelaeus, U. kanivetz = ingressus, U. kudarensis), whose males are nearly 25% larger than females. In the morphological space, we identified two main types of mandibles: the “arctoid” type [U. minimus,U. etruscus, U. arctos, U. rodei (?)], and the “spelaeoid” type (U. spelaeus spelaeus, U. s. eremus, U. kanivetz, U. kudarensis). The intermediate “deningeroid” type includes U. deningeri, U. savini, U. rossicus (males), and U. spelaeus ladinicus. An additional unit is formed by female sample of U. rossicus. The mandible bones are less informative for understanding of cave bear evolution, because in comparison to crania, they have a rather simple shape.
