Figure 14. Hypotheses for the phylogenetic position of Alamosaurus sanjuanensis in previous cladistic analyses. A, Alamosaurus as the sister taxon to Opisthocoelicaudia, or on the stem lineage Opisthocoelicaudiinae (Sereno 1998; Curry Rogers 2005; Wilson 2002; Calvo et al. 2007a; Gonźalez Riga et al. 2009; Zaher et al. 2011; Gonźalez Riga & Ortiz David 2014); B, Alamosaurus as a member of stem lineage Saltasaurinae (Salgado et al. 1997; Calvo & Gonźalez Riga 2003; Gonźalez Riga 2003; Mannion et al. 2013; Saegusa & Ikeda 2014); C, Alamosaurus as a saltasaurid in a basal polytomy with Saltasaurinae and Opisthocoelicaudia (Lacovara et al. 2014); D, Alamosaurus as a lithostrotian titanosaur outside Saltasauridae (Upchurch 1998; Upchurch et al. 2004; Carballido et al. 2011; Carballido & Sander 2014; Poropat et al. 2015). Abbreviations: Op. = Opisthocoelicaudiinae; Sa. = Saltasaurinae.
