Figure 6 in The cranial anatomy of Kombuisia frerensis Hotton (Synapsida, Dicynodontia) and a new phylogeny of anomodont therapsids

Figure 6. Time-calibrated strict consensus cladogram, depicting the survivorship of multiple anomodont lineages across the Permian–Triassic boundary. The stratigraphic ranges of the included anomodont species are plotted on a stratigraphic column that uses the well-established Permian–Triassic assemblage zones from the South African Karoo Basin (Rubidge, 1995) and the international marine stages (Gradstein et al., 2004) as basis. Stratigraphic ranges of the South African taxa are taken from Rubidge (1995) and Angielczyk & Kurkin (2003a), with the addition of Lanthanostegus (Modesto et al., 2002, 2003c) and Colobodectes (Modesto et al., 2003b). The stratigraphic range of Emydops is extended to fit the maximal range as proposed by Angielczyk, Fröbisch & Smith (2005). The stratigraphic position of the holotypic and only specimen of Cistecephaloides boonstrai (Cluver, 1974) is here considered to be in the upper part of the Cistecephalus AZ (Kitching, 1977). Correlation and stratigraphic ranges of the non-South African anomodont taxa from Russia, Scotland and Tanzania are based on Benton & Walker (1985), Gay & Cruickshank (1999), Angielczyk & Kurkin (2003a), Angielczyk (2004), Golubev (2005) and Rubidge (2005). Solid bars represent the known stratigraphic ranges, whereas open and grey bars indicate ghost lineages. Grey bars indicate the ghost lineages of survivors that cross the Permian–Triassic boundary.

Figure 5 in The cranial anatomy of Kombuisia frerensis Hotton (Synapsida, Dicynodontia) and a new phylogeny of anomodont therapsids

Figure 5. Strict consensus cladogram of the six most parsimonious trees (332 steps; CI: 0.494; RI: 0.764; RC: 0.377). Italic numbers indicate bootstrap values above 50% and bold numbers indicate Bremer decay values. No Bremer decay values are shown for nodes that collapse at one extra step. Selected clade names are labelled and discussed in the text.
