Figure 4 in A Heron (Aves: Ardeidae) from the Early Miocene St Bathans Fauna of Southern New Zealand

Figure 4. Ratio diagram (after Simpson, 1941) using measurements of Nycticorax caledonicus as the origin (i.e. log of measurement of Nycticorax caledonicus is equivalent to 0). This diagram indicates that the relative proportions of the fossil heron bones vary in a similar way to those of other herons and so it is likely that the fossil bones come from a single species. Abbreviations: (A), tarsometatarsus, maximum distal width; (B), tarsometatarsus, maximum distal depth; (C), tarsometatarsus, width of trochlea metatarsi III; (D), Tarsometatarsus, estimated total length; (E), coracoid, maximum cranial width (from hum. facet to brachial tub.); (F), coracoid, maximum shaft width (below procoracoid); (G), coracoid, length of humeral facet; (H), coracoid, depth of humeral facet; (I), quadrate, mean of 2 individuals, depth from capit. squam. to cond. lateralis; (J), quadrate, mean of 2 individuals, depth from capit. squam. to cond. medialis; (K), axis, width of facies articularis cranialis; (L), axis, inter-condyle distance; (M), axis, width of single zygapophyses caudalis; (N), axis, depth single zygapophyses caudalis; (O), axis, greatest width (across facies artic. caudalis).Published as part of Scofield, R.
