Abstract:

The Marsh crocodile (Crocodylus palustris) was one of the three crocodilians species found in India. The present study designed to document the Osteometrical details of sacral and coccygeal vertebrae of Marsh crocodile. The bones were prepared from a carcass brought for post-mortem examination. The sacrum and coccygeal vertebrae were 2 and 26 in number respectively. Both the vertebrae were concave on the anterior side and convex on the posterior side of the centrum (Procoelous type). The two sacral vertebrae were separate and typical consisting of a centrum, neural arch and other processes. The expansive ribs of sacral vertebrae formed a robust structure which connects the vertebral column to the pelvic girdle. Among 26 Coccygeal, first 16 were typical and the remaining were atypical vertebrae. Prominent chevron bones were observed up to 11th coccygeal vertebrae attaching to the postero-ventral edges of the centrum. Though the sample size was insufficient, the results of this study provided basic details of sacral and coccygeal vertebrae and helps in understanding the role of axial column in crocodilian locomotion which was functionally different from mammals, even during analogous gaits.
