Project 493: S. J. Nesbitt, C. A. Sidor, R. B. Irmis, K. D. Angeilczyk, R. M. H. Smith, L. A. Tsuji. 2010. Ecologically distinct dinosaurian sister group shows early diversification of Ornithodira. Nature. 464 (4):95-98.
Abstract
The phylogenetic analysis comprises 34 taxa and 290 characters. At least one of the authors personally observed nearly all of the taxa. Erythrosuchus was constrained as the outgroup, and ingroup taxa included a variety of pseudosuchians, pterosaurs, basal dinosauromorphs, and dinosaurs. Specimen numbers or literature sources for each taxon are reported in Table S1 of Nesbitt et al. (2010). Characters are mainly derived from Gauthier (1986), Benton and Clark (1988), Sereno (1991), Sereno and Arcucci (1994), Novas (1996), Benton (1999), Rauhut (2003), Yates (2003), Butler (2005), Langer and Benton (2006), Smith et al. (2007), Irmis et al. (2007a), Butler et al. (2008), and new and revised characters from Irmis (2008) and Nesbitt (2009).The character-taxon matrix was assembled in Mesquite v.2.6 (Maddison and Maddison, 2004). We analyzed our dataset using PAUP* 4.0b10 for Macintosh PPC (Swofford, 2002). Trees were searched for using the parsimony criterion implementedunder the heuristic search option using tree bisection and reconnection (TBR) with 10,000 random addition sequence replicates. Zero length branches were collapsed if they lack support under any of the most parsimonious reconstructions. All characters were equally weighted and the following characters were ordered: 21, 78, 89, 98, 116, 142, 159, 169, 175, 177, 195, 200, 227, 250, 281. Three most-parsimonious trees were found when the scores of Pseudolagosuchus and Lewisuchus were combined, whereas six most parsimonious trees were found when Pseudolagosuchus and Lewisuchus were treated as separate taxa. The strict consensus trees of both analyses are presented in Figures S1 and S2 of Nesbitt et al.(2010). Tree statistics were calculated using TNT v. 1.0 (Goloboff et al., 2003; Goloboff et al., 2008). Bremer support decay indices were calculated in TNT.
