The objective of this study was to obtain data on craniometric parameters in the crab-eating fox (Cerdocyon thous) and to define the general skull type of this species, analysing whether the craniometric classification of domestic dogs can be applied. Eleven skulls of C. thous were included in the analysis, irrespective of age and sex. The location of nine craniometric points established for craniometry in domestic dogs was determined and based on the distances between these points, 17 craniometric parameters were measured. Those parameters were used to calculate the following six craniometric indices: 53.17 ± 2.54 mm skull index, 2.33 ± 0.08 mm craniofacial index, 59.17 ± 3.57 mm neurocranial index, 125.58 ± 6.63 mm facial index, 37.52 ± 2.65 mm basal index and the index of the foramen magnum 54.47 ± 3.48 mm. According to the analysed indices, the skull shape in C. thous can be classified as mesaticephalic.
