We don't know what this creature died from, but millions of years later it is providing important evidence to help us understand in more detail the evolution of brachiosaurid sauropods and a much bigger group of dinosaurs that they belonged to, called titanosauriforms."
They are represented by four taxa: the camarasaurid Lourinhasaurus alenquerensis (Lapparent and Zbyszewski, 1957; Dantas et al., 1998; Mocho et al., 2013a; 2014a), the diplodocid Dinheirosaurus lourinhanensis (Dantas et al., 1992; Bonaparte and Mateus, 1999; Mannion et al., 2012; recently considered as a species of Supersaurus by Tschopp et al, 2015), the basal macronarian Lusotitan atalaiensis, a possible brachiosaurid (Lapparent and Zbyszewski, 1957; Antunes and Mateus, 2003; Mannion et al., 2013) and the turiasaur Zby atlanticus (Mateus et al., 2014).
Based on its slenderness, some authors considered that the Duriatitan humerus might represent a brachiosaurid (e.g., McIntosh, 1990a; 1990b; Upchurch and Martin, 2003; Upchurch et al., 2004).
"As a member of the brachiosaurid (family), it has a long neck and relatively long forelimbs," said Hai-Lu, a scientist at the Chinese Academy of Geological Sciences in Beijing.
