A new sauropod-related paper is now available online:
Philip D Mannion, Paul Upchurch, Daniela Schwarz, Oliver Wings; Taxonomic affinities of the putative titanosaurs from the Late Jurassic Tendaguru Formation of Tanzania: phylogenetic and biogeographic implications for eusauropod dinosaur evolution, Zoological Journal of the Linnean Society, , zly068, https://doi.org/10.1093/zoolinnean/zly068
Giraffatitan, Tornieria, and Dicraeosaurus are the best-known sauropods from the Tendaguru Formation, but the paper by Mannion et al. (2019) provides new insights into non-diplodocoid, non-brachiosaur sauropod diversity in Tendaguru Hill by assigning the long-enigmatic sauropod Tendaguria to Turiasauria, and formally recognizing a set of tail vertebrae previously assigned to Janenschia as the first mamenchisaurid from Africa, bearing the new binomial Wamweracaudia keranjei. Given the placement of Janenschia outside Neosauropoda, and the turiasaur and mamenchisaurid classifications of Tendaguria and Wamweracaudia respectively, it is quite apparent that more than one clade of non-neosauropod sauropods existed in East Africa during the Late Jurassic.
