          Abstract

          SUMMARY: 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.

          RESUMEN: El objetivo de este estudio fue obtener datos sobre los parámetros craneométricos del zorro cangrejero (Cerdocyon thous) y definir el tipo general de cráneo de esta especie, analizando si se puede aplicar la clasificación craneométrica de los perros domésticos. Once cráneos de C. thous fueron incluidos en el análisis, independientemente de la edad y el sexo. Se determinó la ubicación de nueve puntos craneométricos establecidos para la craneometría en perros domésticos y, en función de las distancias entre estos puntos, se midieron 17 parámetros craneométricos. Esos parámetros se usaron para calcular los siguientes índices craneométricos: índice craneal de 53,17 ± 2,54 mm, índice craneofacial de 2,33 ± 0,08 mm, índice neurocraneal de 59,17 ± 3,57 mm, índice facial de 125,58 ± 6,63 mm, índice basal de 37,52 ± 2,65 mm y el índice del foramen magnum 54,47 ± 3,48 mm. Según los índices analizados, la forma del cráneo en C. thous se puede clasificar como mesaticefálica.
