Hypothesized phylogenetic position of <i>Sarmientosaurus musacchioi</i> gen. et sp. nov. within Titanosauria.

<p>(<b>A</b>) Strict consensus of three trees of 590 steps based on initial analysis of matrix of 22 ingroup taxa and 337 osteological characters. (<b>B</b>) Strict consensus of 32 trees of 536 steps based on analysis of modified matrix of 25 ingroup taxa and 295 osteological characters. (<b>C</b>) Strict consensus of seven trees of 434 steps based on analysis of matrix of 25 ingroup taxa and 246 osteological characters (modified from Zaher et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0151661#pone.0151661.ref014" target="_blank">14</a>]). (<b>D</b>) Strict consensus of 14 trees of 447 steps based on analysis of matrix used in (<b>C</b>) with the addition of the titanosauriform <i>Abydosaurus</i>. All analyses recover <i>Sarmientosaurus</i> as a basal lithostrotian titanosaur, intermediate in phylogenetic position between the basalmost lithostrotian <i>Malawisaurus</i> and more derived titanosaurs.
