Fig. 11 in The Basal Penguin (Aves: Sphenisciformes) Perudyptes Devriesi And A Phylogenetic Evaluation Of The Penguin Fossil Record

Fig. 11. Strict consensus of 420 most parsimonious trees of 4492 steps fom the primary analysis. Bremer support values are indicated above branches. Support values reflect the low proportion of codable informative cells for several fossil taxa and the high proportion of missing data in all fossil taxa (all 6000+ molecular characters are missing data for all fossils). For a more complete understanding of support within extant clades, see Bertelli and Giannini (2005) and Baker et al. (2006).
