Figure 23. Palaeobiogeographical affinities of the bryozoan assemblage from the Zhongba Formation (Zhongba). Top: dendrogram of the cluster analysis using Jacquard's similarity index (unweighted pair-group average algorithm), and bottom: plot of non-metric MDS analysis made with Jacquard's similarity index. Areas: Pamir (Tajikistan), Oman (Batain Coast), Iran (central Iran, Chili Formation), Xainza (southwestern Tibet, Xiala Fm.), Thailand, Urals, Western Xinjiang (Baliqliq Group), and W.
