Fig. 7 in A new Maastrichtian species of the centrosaurine ceratopsid Pachyrhinosaurus from the North Slope of Alaska
Fig. 7. Results of phylogenetic analysis. One of three equally most parsimonious trees (length = 107, C.I. (consistency index) = 0.8131, R.I. (retention index) = 0.8291) from our analysis set upon the Late Cretaceous timescale. Ranges of ceratopsian taxa other than Pachyrhinosaurus perotorum from Sampson and Loewren (2010). Timescale dates derived from Walker and Geissman (2009). Solid thick bars indicate well constrained range of a taxon. Open thick bars indicate poorly constrained or estimated range of a taxon. Open circles at nodes indicate named node−defined clades. Arcs on branches indicate stem−defined lineage names. Divergence points on tree are arbitrarily drawn, and are not based on calculations of lineage divergence dates. Abbreviations: Cen., Cenomanian; Con., Coniacian; Dan., Danian; Pal., Paleocene; Sa., Santonian; Tur., Turonian.
