  • Can osteophagia provide giraffes with phosphorus and calcium? 
    Bredin, I.P.; Skinner, J.D. (John Dawson), 1932-; Mitchell, Graham (Agricultural Research Council, ARC-OVI and the University of Pretoria, 2008-03)
    The daily requirement for calcium and phosphorus by giraffes to sustain the growth and maintenanceof their skeletons is large. The source of sufficient calcium is browse. The source of necessary phosphorus is obscure, but ...
  • On reconstructing Giraffa sivalensis, an extinct giraffid from the Siwalik Hills, India 
    Van Sittert, Sybrand J.; Mitchell, Graham (PeerJ, 2015-08)
    Giraffa sivalensis occurred during the Plio-Pleistocene period and probably represents the terminal species of the genus in Southern Asia. The holotype is an almost perfectly preserved cervical vertebra of disputed ...
  • Scaling of the appendicular skeleton of the giraffe (Giraffa camelopardalis) 
    Van Sittert, Sybrand J.; Skinner, John; Mitchell, Graham (Wiley, 2015-05)
    Giraffes have remarkably long and slender limb bones, but it is unknown how they grow with regard to body mass, sex and neck length. In this study we measured the length, medio-lateral diameter (ML), cranio-caudal diameter ...
  • The structure and function of giraffe jugular vein valves 
    Mitchell, Graham; Van Sittert, Sybrand J.; Skinner, J.D. (John Dawson), 1932- (Southern African Wildlife Management Association, 2009-10)
    When a giraffe (Giraffa camelopardalis) lowers its head to drink, blood could enter the jugular vein from the inferior vena cava or regurgitate from the jugular veins into the cranial veins. We investigated the anatomy of ...
