Figure 27 in New sauropod dinosaur from the Lower Cretaceous of Morella (Spain) provides new insights on the evolutionary history of Iberian somphospondylan titanosauriforms

Figure 27. Time-calibrated phylogenetic tree, showing geographic distribution of camarasaurids and non-titanosaurian titanosauriforms. Topology corresponds to a consensus strictus from trees obtained with implied weight analysis (see Analyses II) and resolved after the a posteriori deletion of Abydosaurus, Nopcsaspondylus, Padillasaurus, and Sarmientosaurus in TNT. Global palaeogeographic reconstructions from Fossilworks (http://fossilworks.org/) showing the distribution of Late Jurassic (150 Ma) and Early Cretaceous (126 Ma) of brachiosaurids in (pink) and non-titanosaurian somphospondylans (light brown). An interrogation mark is placed on two occurrence points for two Late Jurassic titanosauriforms, Oceanotitan and Autrodolodocus, which present an uncertain phylogenetic position, but were referred as putative somphospodylans by some authors.
