Figure 5 in The giraffe (Giraffa camelopardalis) cervical vertebral column: a heuristic example in understanding evolutionary processes?

Figure 5. Graph of total cervical vertebral length (TCL) vs. individual vertebral length of all the extant specimens studied. Note the way in which the giraffe cervical vertebrae scale in accordance with those seen in the other extant ungulates studied, with the only exception being the youngest giraffe (which was excluded from the regression analysis, but was placed on the graph for comparison).
