Photo 1 shows a rhino (rhino 1) where a height-marker is visible behind the animal, just in front of its ears. The height of the marker is one meter (32 mm on the picture, about 40 mm at rhino's shoulder when accounted for perspective). The height at the shoulder of this individual is estimated to be 130 cm (52 mm on the picture/40 mm) which is slightly larger than the estimate presented (110- 120 em) by Sung et al. (1 998).
Sung et al. (1998) estimate that the R. s. annamiticus is about 75 to 80% of the size of a R. s. sondaicus. They base this estimate on the ratio of the width of the hind feet measured in Cat Loc (20-23 cm) versus those recorded in Ujong Kulon (25-28 cm). Using this relation in size and estimating the weight of a R. s. sondaicus to be 1,600 kg, it may be estimated that a R. s. annaniiticus weighs about 650 to 800 kg (1,600 kg x 0.753 to 0.83).
