separated into true Brachiosaurus (B. altithorax) and Giraffatitan (B. brancai), based on Taylor (2009). Based on this newer and more expansive analysis, Europasaurus was found to be in a similar placement, as a basal camarasauromorph closer to titanosaurs than Camarasaurus. However, Euhelopus, Tehuelchesaurus, Tastavinsaurus and Galvesaurus were placed between Europasaurus and Brachiosauridae. Placement as a brachiosaurid In a 2012 analysis of the phylogeny of Titanosauriformes, D'Emic (2012) considered Europasaurus to belong to Brachiosauridae, instead of being basal to the earliest brachiosaurids. The phylogeny resolved the most true brachiosaurids to date, although several potential brachiosaurids were instead determined to belong to Somphospondyli (Paluxysaurus, Sauroposeidon and Qiaowanlong). However, D'Emic was tentative in considering Europasaurus to be a confirmed brachiosaurid. While there was strong support in the phylogeny for its placement, Europasaurus, one of few basal macronarians with a skull, lacks multiple bones that display characteristic features of the group, such as caudal vertebrae. The cladogram below on the left illustrates the phylogenetic results of D'Emic (2012), with Euhelopodidae and Titanosauria collapsed. A later analysis on titanosauriformes agreed with D'Emic (2012) in the placement of Europasaurus. It formed a polytomy with Brachiosaurus and the "French Bothriospondylus" (named Vouivria) as the basalmost brachiosaurids. Next most derived in the clade was Lusotitan, with Giraffatitan, Abydosaurus, Cedarosaurus and Venenosaurus forming a more derived clade of brachiosaurids. The "twisted" teeth of Europasaurus were found to be one of the unique features of Brachiosauridae, which could mean a confident referral of isolated sauropod teeth to the clade. A further phylogenetic analysis was performed on Brachiosauridae, based on that of D'Emic (2012). This phylogeny, conducted by D'Emic et al. (2016), resolved a very similar placement of Europasaurus within Brachiosauridae, although Sonorasaurus was placed in a clade with Giraffatitan, and Lusotitan was placed in a polytomy with Abydosaurus and Cedarosaurus. The remaining tree was the same as in D'Emic (2012), although Brachiosaurus was collapsed into a polytomy with more derived brachiosaurids. Another phylogeny, Mannion et al. (2017) found similar results to D'Emic (2012) and D'Emic et al. (2016). Europasaurus was the basalmost brachiosaurid, with the "French Bothriospondylus", or Vouivria, as the next most basal brachiosaurid. Brachiosaurus was placed outside of a poltomy of all other brachiosaurids, Giraffatitan, Abydosaurus, Sonorasaurus, Cedarosaurus and Venenosaurus. A 2017 phylogeny, that of Royo-Torres et al. (2017), resolved more complex relations within Brachiosauridae. Besides Europasaurus as the basalmost brachiosaurid, there were two subgroups within the clade,
