ArticleItem Open Access Gross Anatomical Studies on the Sternum and Ribs of White-Rumped Vultures (Gyps bengalensis)(2012-12) Sathyamoorthy, OR; Thirumurugan, R; Palanivel Rajan, M; TANUVASThe sternum of white-rumped vultures was broad, large, pneumatic and rectangular in shape. The sternal crest was triangular. The straight cranial border of the sternum presented a long, deep groove to receive the distal end of the coracoid bone. The sternal spine was thick and prismatic and arose from the ventral edge of cranial border alone. The cranio-lateral process was short and thin. The lateral borders presented five articular cylinders for second to sixth sternal ribs and pneumatic foramina. The dorsal surface of the sternum was highly concave and had pneumatic foramina. The caudo-lateral process joined the caudal narrow part of the sternum and enclosed a large oval foramen. The processus thoracicus was absent. The caudal border presented a triangular projection and was completely closed without notchesArticleItem Open Access Gross Morphological Studies on the Pelvic Girdle of Spot-Billed Pelicans (Pelecanus philippensis)(2012-12) Sathyamoorthy, OR; Thirumurugan, R; Senthil Kumar, K; Jayathangaraj, MG; TANUVASThe pelvic bone consisting of ilium, ischium and pubis were fused with each other and also with the transverse and spinous processes of synsacral vertebrae. The fossa renalis was shallow. In the post-acetabular part, the dorsal surface had 7 or 8 openings on either side of the median ridge. The perforated acetabulum was formed by all the three bones. The anti-trochanter was present caudo-dorsal to the acetabulum. The cranial part of ischium was a thick rod-like portion. The caudal part of ischium was quadrilateral in shape. The ischiatic foramen was an elongated, large and oval shaped. Incisura pubo-ischiadia was long. The pubis was a thin, rib-like bony rod and projected caudally beyond the ischium. The processus pectinealis was absent.
