The studies of the craniometric features in European beaver ( Castor fiber L.,1758) were performed using the material of 25 skulls, including 12 females and 13 males from the Pomorze and Kujawy region. For each skull 30 measurements were taken to provide the grounds for the variation in craniometric features and the significance of differences between sexes. In two cases there were observed significant and in three – highly significant differences between males and females of that species. Interestingly, in the shaft of the occipital bone there was found a profound and vast fossa of the skull base.

Na vsaki lobanji je bilo opravljenih 30 meritev, ki so bile podlaga za ugotavljanje raznolikosti v kraniometriAnih znaAilnostih in njihovem pomenu pri razlikah med spoloma. V dveh primerih so opazili znaAilne in v treh primerih zelo znaAilne razlike med samci in samicami. Zanimivo je, da je v zatilnici najdena globoka in obseA¾na jama na bazi lobanje.
