• Phylogenetic taxonomy and classification of the Crinoidea (Echinodermata) (2017, background): “…2005) has become increasingly common in paleontology (e.g., Smith, 1984, 1994; Holtz, 1996, 1998; Sereno, 1997; Padian et al., 1999; Brochu and Sumrall, 2001; Carlson, 2001; Carlson and Leighton, 2001; Brochu, 2003; Forey et al., 2004; Sereno et al., 2005; Butler et al., 2008; Kelley et al., 2013).”
• Phylogeny of the ankylosaurian dinosaurs (Ornithischia: Thyreophora) (2012, background): “Stegosauria and Ankylosauria form a monophyletic Eurypoda, with Scelidosaurus as a basal thyreophoran (Sereno 1999; Norman et al. 2004; Butler et al. 2008; Maidment et al. 2008), rather than the sister taxon to Ankylosauria (Carpenter 2001; Parish 2003).”
• A reappraisal of the Cretaceous non-avian dinosaur faunas from Australia and New Zealand: evidence for their Gondwanan affinities (2010, methodology): “Regarding (2), in the basal ornithischians Pisanosaurus (Bonaparte 1976), Heterodontosaurus (Norman et al. 2004; UCMP 129614), Eocursor (Butler et al. 2008) and Lesothosaurus (Sereno 1991), the dentary is elongated, thus representing the plesiomorphic condition of the clade.”
• The Early Evolution of Archosaurs: Relationships and the Origin of Major Clades (2011, background): “However, within Ornithischia, extensive planar wear facets are present in Pisanosaurus (PVL 3577) and Heterodontosaurus (SAM-PK-1332), whereas they are absent in Lesothosaurus (BMNH R8501) and Scutellosaurus (MNA 175).”
• Evaluating hypotheses for the early diversification of dinosaurs (2010, background): “A variety of detailed phylogenetic studies have focused on basal dinosaurs, clarifying understanding of the early evolutionary history of these groups (Smith et al. 2007; Yates 2007a, b; Butler et al. 2008; Irmis 2008; Nesbitt et al. 2009b, 2010).”
• Vertebrate Succession in the Ischigualasto Formation (2012, result): “None of the subsequent studies contradicted the original proposal, finding Pisanosaurus as the basalmost member of Ornithischia (Bonaparte, 1976; Weishampel and Witmer, 1990; Sereno, 1991b; Langer and Benton, 2006; Irmis et al., 2007a; Butler et al., 2007, 2008a, 2008b).”
• The Locomotor Musculature of Basal Ornithischian Dinosaurs (2011, background): “Heterodontosaurids have been proposed to be the most basal ornithischians (Butler et al., 2008), but the phylogenetic position of this clade is less stable than that of Lesothosaurus, with alternative phylogenies nesting heterodontosaurids within Cerapoda, as the sister group of Marginocephalia…”
• The anatomy of the basal ornithischian dinosaur Eocursor parvus from the lower Elliot Formation (Late Triassic) of South Africa (2010, methodology): “Heterodontosaurus tucki, Early Jurassic, southern Africa: SAM-PK-K337 (holotype), SAM-PK-K1332 (referred specimen: Santa Luca, 1980), SAM-PKK10487 (referred specimen: Butler et al., 2008a); Santa Luca (1980); Butler et al. (2008a).”
