Sixteen African giant rats (Cricetomys gambianus Waterhouse), consisting of 8 male and 8 female rats, were used to determine neurocranial measurements of the skulls. The mean neurocranial volume was 5.06 ± 0.05 mL, neurocranial length was 3.33 ± 0.08 cm, and the neurocranial height and index were 1.39 ± 0.04 cm and 41.74%, respectively. The mean whole skull length and height were 6.32 ± 0.06 cm and 2.98 ± 0.05 cm, respectively. The skull without the mandible was 1.83 ± 0.02 cm in height, and the skull index was 28.41 ± 0.58. The height of the skull of the African giant was approximately half (47%) of the skull length. The mean height and width of the foramen magnum were 0.78 ± 0.01 cm and 0.96 ± 0.02 cm, respectively, while the foramen index was below 100 at 81.46 ± 1.42. Parameters for the whole skull height and foramen magnum width showed significant difference between both sexes at p < 0.05. The foramen magnum showed shape variations and there were multiple hypoglossal foramina in over 87% of the rats. This study, in conclusion, highlighted the possibility of the estimation of the brain density and the use of the African giant rat for cranial pressure experiments.

The aim of the investigations was the description of foramen magnum morphology. Fourteen skulls of American Staffordshire terrier pups were examined. The morphology of the foramen magnum was described, its height and width were measured, and the index of the foramen magnum (width/height × 100) was calculated. The height of the skull, maximum width and maximum height of the occipital condyle were also measured. In all the examined skulls the shape of the foramen magnum was regular and ellipsoidal. The average height of the foramen magnum was 5.7 mm, the average width - 6.05 mm. The value of the foramen magnum index was 106.82. The average skull height was 22 mm. The average maximum height of the occipital condyle was 5.33 mm and its average maximum width was 2.85 mm. There were no differences between females and males in all parameters. The shape of the foramen magnum was regular. The occipital condyli were symmetrical.
