Aetosauria: a clade of armoured pseudosuchians from the Upper Triassic continental beds (2013, methodology): “Aetosauria is nested within Pseudosuchia, the crocodile lineage of Archosauria; however, the phylogenetic relationships of aetosaurs with other high-level suchians are currently a matter of debate (e.g. Gower & Sennikov 1996; Gower & Walker 2002; Nesbitt 2007, 2011; Brusatte et al. 2010; Desojo et a”
Macroevolutionary patterns in the evolutionary radiation of archosaurs (Tetrapoda: Diapsida) (2010, neutral): “An even larger and more comprehensive phylogeny of basal archosaurs was recently conducted by Sterling Nesbitt as part of his PhD dissertation (Nesbitt 2009a), and the results have been presented briefly in an abstract (Nesbitt 2009b) and in this volume (Nesbitt et al.”
Osteology of Eoraptor lunensis (Dinosauria, Sauropodomorpha) (2012, result): “Other authors examined the fossil material and drew conclusions similar to those we suggested in 1993—that Eoraptor was a basal theropod (Novas, 1994; Tykoski, 2005; Nesbitt et al., 2009; Ezcurra, 2010; Nesbitt, 2011).”
The origin(s) of extant amphibians: a review with emphasis on the “lepospondyl hypothesis” (2013, background): “58A) found the late Early Triassic (probably older than 247 Ma) Xilousuchus Wu, 1981, and possibly the coeval Vytshegdosuchus Sennikov, 1988, to be archosaurs; he consequently recommended (Nesbitt 2011: 253) that “a date greater than 245 Ma should be used to calibrate molecular divergence dates”.”
The Femoral Ontogeny and Long Bone Histology of the Middle Triassic (?Late Anisian) Dinosauriform Asilisaurus kongwe and Implications for the Growth of Early Dinosaurs (2016, background): “…of the femur (character state 304[1] of Nesbitt et al., 2010; for detailed explanation and illustration of this and other Nesbitt et al., 2010, character states, see Nesbitt, 2011); and straight medial articular facet of the proximal portion of the femur (character state 309[1] of Nesbitt, 2010).”
Postcranial Osteology of Azendohsaurus madagaskarensis (?Middle to Upper Triassic, Isalo Group, Madagascar) and its Systematic Position Among Stem Archosaur Reptiles (2015, background): “This uncertainty, in turn, raises a number of other questions including: How many archosauromorph subgroups crossed the Permian-Triassic boundary and when did the highly disparate subgroups of archosauromorphs diversify and transform into the strange animals that appear in the Middle or Late Triassi”
Vertebrate Succession in the Ischigualasto Formation (2012, methodology): “The clade has been positioned among basal theropods (Reig, 1963; Sereno and Novas, 1992, 1994; Novas, 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.”
Anatomy, phylogeny and palaeobiology of early archosaurs and their kin (2013, background): “These crown diversifications are shallow in time compared to the much deeper divergence of the crocodylian and avian stem lineages in the Triassic, approximately 250 Ma ago (Butler et al. 2011; Nesbitt 2011; Nesbitt et al. 2011).”
The Late Triassic dinosauromorph Sacisaurus agudoensis (Caturrita Formation; Rio Grande do Sul, Brazil): anatomy and affinities (2013, methodology): “The morelateral groove is central on the bone and represents the popliteal fossa (Yates 2003), i.e. ‘intercondylar groove’ (Butler 2010), that extends for the whole distal third of the femur (Irmis et al. 2007a; Nesbitt et al. 2007, 2010; Nesbitt 2011).”
