Morphometric data. A Linear measurements describing body shape: head length (1), head width (2), head depth (3), neck length (4), body length (5), hip width (6), tail length (7), tail width (8), and tail depth (9). B Linear measurements describing limb shape: upper arm length (1), lower arm length (2), hand length (3), hand width (4), finger IV length (5), upper leg length (6), lower leg length (7), foot length (8), foot width (9), and toe IV length (10). C Landmark configuration used to characterize head shape: tip of snout (1), anterior edges of supraocular semicircles (2–3), medial edges of supraocular semicircles (4–5), posterior edges of supraocular semicircles (6–7), anterior edges of tympanum (8–9), posterior edges of nuchal fold (10–11), and anterior edge of nuchal fold (12); the blue lines indicate sliding semi-landmarks (13–32)
