28 ISTVÁN VÖRÖS Fig.l. Egervár-Sárvíz canal. Locality of the aurochs skeletal parts at Egervár. /. ábra. Egervár-Sárvíz csatorna. Az őstulok csontvázának előkerülési helye. was formed bordered bv a bone lath. The proc. transversus and the fovea costalis transversus are well developed. The physiological length of the complete dorsal vertebral column (I—XII.) of the Egervár aurochs was 800 mm. The physiological length of the body was between 65—70 mm. The shortest dorsal vertebra of the aurochs from Egervár was the VI. vert, (length 65 mm). The smallest breadth of the corpus vertebrae was observed for the l s t-3 r d vertebrae (58-38 mm), decreasing for the 4 t h-9 t h vertebrae (45-34 mm), and gradually increasing for the 10 t h-12 th vertebrae (37-38 mm). The smallest lateral length observed across the incisura vertebralis cranialis and caudalis was gradually increasing from the l s l to the 12 th vertebra (33-60 mm). In the caudal region of the dorsal vertebrae all the proc. transversuses were well developed, with articular surface observable for the decreasing head of the ribs. In the case of the 12 t h vert., the fovea costalis caudalis is missing that actually shows that it was the last dorsal vertebra. The form of the 2 nc l and 3 r d vert. proc. spin, is especially characteristic of the aurochs: the vertical axis of the processus spinosus corpus is broken in the middle and its lower and upper part encloses an angle; the proc. spin, is oriented at the lower part backwards in a caudo-dorsal manner, while upwards it is standing dorsally. "file 4 T H11 1, 1 vertebrae proc. spin, are standing, with decreasing length, caudo-dorsally while the 12 t h vert. proc.spin is already standing vertically. The length (or height) of the spinosus processus on the 2 nc l dorsal vertebra is shorter on the aurochs from Egervár than on the Bison (DEGERB0L-INVERSEN 1945.). The length of the proc. spin, measured from front to back are much longer than that of the Bison. The form of the proc. spinosus, their form and dimensions (Table I.) prove that these dorsal vertebrae used to belong to a Bos.
