Figure 6 in Redescription of 'Amyzon' brevipinne and remarks on North American Eocene catostomids (Cypriniformes: Catostomidae)

Figure 6. Phylogenetic position of Wilsonium brevipinne. Strict consensus of 106/74/5 equally most parsimonious cladograms (all of a similar tree topology) resulting from the parsimonybased analyses of a matrix of 71 taxa and 157 characters using the heuristic search of PAUP 4a169 (Supplemental material 3), and the traditional and new technology searches of TNT 1.5, respectively. The three equally most parsimonious cladogram have 812/811/811 steps, respectively, all with Consistency Index (CI) = 0.38 and Retention Index (RI) = 0.78. Numbers above branches indicate Bremer support (TNT). Wilsonium brevipinne is resolved as the most basal linage of the family Catostomidae with strong support.
