Dendrograms from cluster analyses on the ungulate assemblages of Western Europe during the time interval MP25 to MN4, at the familial and specific levels. The similarity indices used are the Dice Index and the Jaccard Similarity Index, and the clustering techniques are the “Unweighted Pair-Group Method with Arithmetic mean” (UPGMA) and the “Single Linkage” (SINGL)
