ABSTRACT
The measurements of craniometric characteristics in raccoon dog (Nyctereutes procyonoides Gray) involved the use of 110 skulls, including 52 male and 58 female skulls from the region of Pomorze and Kujawy. For each skull 24 measurements were taken to facilitate defining craniometric characteristics, their proportions and correlations. The present research shows clearly a shortening of the viscerocranium, as compared with other Canidae, similar to the length of the neurocranium part. Investigating the cranial variation in the skull parameters in raccoon dog, it was found that the highest coefficient of variation in males concerns the length of the frontal bone in the sagittal plane /Br-N/ and the height of the occiput /Op-O/, while in females – the placement of the eye sockets /Ect-Ect/. The calculations made show the range if variation, including the cerebral skull, especially the cerebral skull height /Sph-Br/ and the height of the occiput /Op-O/. A high value of the coefficient of variation was observed also for the cranial cavity volume. In ten measurements there were observed significant differences between the sexes.
Key words: raccoon dog, skull, craniometric measurements, correlation.
