• The phylogeny of the ornithischian dinosaurs (2008, methodology): “Irmis et al. (2007) additionally stated that in ornithischians the maxillary ridge was separated from the ventral margin of the external antorbital fenestra.”
• The higher-level phylogeny of Archosauria (Tetrapoda: Diapsida) (2010, background): “Comparatively low CSSI values are also seen with the recent analyses of Weinbaum & Hungerbühler (2007) at 0.85 and Irmis et al. (2007a) at 0.88.”
• A Late Triassic dinosauriform from south Brazil and the origin of the ornithischian predentary bone (2007, background): “Other alleged Triassic ornithischians include an heterodontosaurid from Patagonia (Baez and Marsicano 2001), an undescribed basal neornithischian from southern Africa (Butler 2005), and fragmentary material from Western USA (Chatterjee 1984; Hunt and Lucas 1994; Heckert 2004; Irmis et al. 2006), Eur”
• The anatomy of the basal ornithischian dinosaur Eocursor parvus from the lower Elliot Formation (Late Triassic) of South Africa (2010, background): “Recent phylogenetic analyses of basal dinosaurs generally resolve Herrerasaurus as a basal saurischian, outside of the Theropoda–Sauropodomorpha split (Langer, 2004; Langer & Benton, 2006; Irmis et al., 2007b).”
• The Early Evolution of Archosaurs: Relationships and the Origin of Major Clades (2011, methodology): “Tibia (or fibula)-femur length: (0) femur longer or about the same length as the tibia; (1) tibia longer (modified from Gauthier, 1986; Sereno, 1991a; Juul, 1994; Benton, 1999; Irmis et al., 2007a).”
• Vertebrate Succession in the Ischigualasto Formation (2012, background): “…1994; Rauhut, 2003; Ezcurra and Novas, 2007; Nesbitt et al., 2009, 2010; Nesbitt, 2011; Sues et al., 2011), as outgroups to other saurischians (Langer, 2004; Langer and Benton, 2006; Irmis et al., 2007b), or as non-dinosaur dinosauriforms (Gauthier, 1986; Brinkman and Sues, 1987; Novas, 1992).”
• The origin and early radiation of dinosaurs (2010, background): “The recent discovery of Late Triassic representatives of these groups (e.g., Dzik, 2003 and Irmis et al., 2007a) demonstrates that they co-existed with dinosaurs for at least 15 million years.”
