Osteometry of the skull of one-humped camels. Part I: immature animals.

The aim of this study was to investigate osteometric indices of immature camels (2-3 years old) in Nigeria. The cranial length, viscerocranial length, maximum zygomatic width, neurocranial volume, skull and facial index for females and males were 22.1 cm and 22.3 cm; 16.3 cm and 16.7 cm; 15.8 cm and 16.1 cm; 479 ml and 496 ml; 40.9 and 41.3, and 96.4 and 96.2 respectively. The mean orbital horizontal and vertical diameters of young camels were similar to each other giving a near complete circular shape. The foramen magnum index was over 100 because of a relatively higher height than width. The data were compared with those of other types of immature camels in the literature and will be useful for anatomical, developmental, anthropological and clinical studies of camels.
