Abstract
The atlas has a butterfly shape, presents an alary hole that is united with the
vertebral hole through a wide alary trench. The transversal hole is found on the caudal edge of
the wings of the atlas. The axis is particularized by the development of a spinal process,
oblong anterior-posterior. The caudal edge of the spinal process is callous, provided with a
deep muscular fosse delimited laterally by a bony crest. The dens, cylindrical process presents
in front a plan surface cut oblique. The cervical vertebras III-VII are characterized by an
elongation of transversal processes, ended with a well-defined tuberous tubercle
